EC2B Flameproof and Increased Safety Control Boxes

Safety Precautions• Use explosion-proof electrical equipment that are applicable for use
in hazardous areas (potentially explosive atmosphere where explosivegas or vapor may exist), otherwise explosion or fire hazard may result.
• EC2B control boxes can be installed only in zones 1 and 2. Do not use
in zone 0. In North America, the EC2B can be installed in Division 2
areas, but cannot be installed in Division 1 areas.
• Turn power off to the EC2B control box before installation, removal,
wiring, or maintenance, otherwise explosion, fire hazard, or electric
shock may result.
• Special skills and knowledge of explosion protection, electric systeminstallation, and relevant laws/regulations are required to transport,
install, wire, operate, repair, and inspect the EC2B control box. People
without such expertise must not use the EC2B control box, otherwise
damage or accident may result.
• Do not modify the EC2B, otherwise damage or accident may result.
• Do not use a damaged EC2B control box, otherwise damage or
accident may result.
• When connecting external devices, make sure that each cable isconnected to the correct terminal, otherwise electric shock, fire
hazard, or explosion may result.
• Use wires of a proper size to meet voltage and current requirements.
Incorrect wiring may cause abnormal temperature rise and lead to fire
hazard and explosion.
• Connect the grounding terminal to a proper ground, otherwise electric
shock, fire hazard, or explosion may result.
• Do not sit on or hang from the EC2B control box, otherwise damage,personal injury, or accident may result.

Operating Instructions
Installation Area
• Do not install the EC2B control box in an environment where morethan IP65 protection degree (more than Type 4X in North America) is
required.
• Use the EC2B in an ambient temperature range of -20oC to +50oC.
When using the EC2B in areas that may be higher than 50oC, installa shade (page 22) to the box so that the box temperature does notexceed 50oC.
When the potentiometer is installed, use in an ambient temperature
range of -20oC to +40oC. Make sure that the box temperature does
not exceed +40oC.

Installation• Wall mount
Use four M6 bolts for 1-column, four M8 bolts for 2- and 3-column,
or other methods with equivalent strength to install the control box.
Mounting tab thickness is 1.5mm for 1 column and 2mm for 2, 3, and4 columns. (See dimensions).
• Pole mount
Use four M12 bolts or other methods with equivalent strength toinstall the control box.
Use flat washers to prevent scratches on the pole base coating.
• If bolts become may loose due to vibration, use spring washers.
If bolt corrosion is anticipated, use anti-corrosion bolts or othercountermeasures.

25• Do not open the lid of the EC2B control box when it is energized,
otherwise electric shock, fire hazard, or explosion may result.
• Operate the EC2B control box at the rated current and voltage
specified in this catalog, otherwise short-circuiting, fire hazard, or
explosion may result.
• When measuring the insulation resistance of the EC2B control box,
make sure that potentially explosive atmosphere of explosive gas orvapor does not exist in the vicinity, otherwise explosion may result.
Also, do not touch the terminals without paying attention, otherwise
electric shock will result.
• Do not place any obstacles in front of the nameplate.
• Do not remove the nameplate.
• When opening the lid for wiring, maintenance or inspection, makesure that substances such as dust, concrete powder, or metal powder
do not enter inside the box, otherwise contact failure or insulation
failure may result.
• Do not drop the EC2B control box during transportation.
• Be sure to open the carton the right way up, otherwise damage or
personal injury may result.
• Check that the product is what you have ordered. Using an incorrectmodel might result in malfunction or accident.
• Stop operation immediately if abnormal operation occurs. Otherwise,a secondary accident may occur.
• The surface temperature of the EC2B control box may become
extremely hot during operation. Before maintenance or inspection of
the EC2B, be sure to wear gloves to prevent burning your hand.

Notes on Emergency Stop Switches
When using the emergency stop switches on safety-related parts ofthe control system, observe safety standards and regulations of therelevant country or region. Also be sure to perform a risk assessment
before operation.

Opening/Closing the Lid• Use a Philips screwdriver to loosen lid mounting screws. While holding
the unhinged side, open the lid slowly without exerting excessive
force on the hinge.
• Before closing the lid, make sure of the following:-No foreign substances are on the packing or joint surfaces.
-No displacement of the waterproof packing.
-Wires are not caught between the joint surfaces.
• Close the lid slowly and tighten the screws to a proper torque of 1.6
to 2.4 N·m.

Limitation of the Operating Current• Major heat sources comes from the wiring which is connectedto the control box. Therefore, not only the operating current but
wiring conditions (size, no. of wires, no. of wire bundles) may causetemperature rise. When wiring, observe the following conditions.
· Stranded wire: 1.5 to 2.5 mm2 (UL/c-UL certified)
1.25 to 2.5 mm2 (other)
Solid wire: ø1.2 to ø1.6 mm (AWG106-14 )· Maximum no. of wires per bundle: 16· Maximum operating current: 10A• When using the control box, use a heat resistant cable of 70°C
minimum.
• Determine the operating current so that the total heat value of 1 wirebundle is below 300 [A2 × wires]. Also, when calculating the heatvalue, take the current fluctuation (10%) into consideration.

EC2B Flameproof and Increased Safety Control Boxes
OperatingInstructions
Instructions
For control units EU2B

*1: Make sure that the number of wires per bundle is a maximum of 16
by reducing the wiring or by jumper wiring. The maximum numberof wires per bundle may need to be further reduced depending on
the wire size, cable gland, or conduit size.
*2: The allowable current value (reference) when applying current
evenly to all circuits of the maximum number of circuits.

Wiring Construction• Observe the laws and regulations in each country concerning wiringconstruction.
• Use cable wiring or metal conduit wiring for installation in hazardous
locations. If foreign objects or water may enter the box, install asealing fitting near the cable entry of the box and seal the control box
using a compound.
• Standard type control boxes do not contain a terminal block. Wire thecontrol units directly.

WiringApplicable Wires
Stranded wire: 1.25 to 2.5 mm2, solid wire: ø1.2 to ø1.6 mm(AWG16 -14)
• Do not connect more than 2 wires to the same terminal.

Applicable crimping terminal• Ring terminals cannot be used for EU2B control units (IP20) and EC9F
buzzers (IP20).
• Ring and spade terminals cannot be used for IP20 clamp typeterminal blocks and potentiometers.
• When connecting 2 ferrules to EU2B control units (IP20) and EC9F
buzzers (IP20), use ferrules without insulating sheath.

Protective Grounding
Protective grounding must be performed according to the installation
environment and rating requirements. Observe laws and regulations set
by each country.
• Connect the M4 grounding terminal of the EC2B control box to aproper ground (grounding resistance 10Ω maximum). When operating
the EC2B control box by connecting to circuits of 300V or below, thegrounding resistance must be 100Ω maximum.
• When using cables, connect one of the cable cores to the grounding
terminal in the enclosure.
• If the grounding terminal in the enclosure cannot be used, use the M4
grounding terminal on the outside of the enclosure for wall mount, or
the M6 grounding terminal of the pole base for pole mount.
Recommended tightening torque:M4: 1.0 to 1.3 N·m
M6: 3.9 to 5.4 N·m
For grounding, use appropriate wires (size, material, insulation) that
can tolerate the expected maximum grounding current. Be sure toprotect the grounding wire with protection, such as metal conduit, fromexternal damage.

Maintenance and Inspection• Observe laws and regulations set by each country.
• Do not open the lid when inspecting the EC2B while it is energized.
• Never disassemble the control box.
• Do not use tools that cause sparks during maintenance andinspection.
• When using measuring devices, use explosion-protected types.
• When the EC2B needs to be disassembled or assembled formaintenance or repair, contact IDEC.
