Fittings and Reducers

Terminal blocks are not supplied with the standard control boxes (without wiring). When wiring inside the control box is required, specify the wiring circuit.
The terminal block type used on the control boxes with wiring depends on theterminal style of the control unit.

Reducers installed at the bottom of the control box are as follows: 1 column: 1
reducer, 2 columns: 2 reducers, 3 columns: 3 reducers. Material is nickel-plated
brass. Use cable lead-in fittings that are commercially available. See the following

Operating Instructions
Installation Area

➀ Apply 10A to 1 circuit, 1A to the remaining 7 circuits:

Do not install the EC2B control box in an environment where more than IP65
protection degree (more than Type 4X in North America) is required.

{(10A × 1.1)2 × 2 wires} + {(1A ×1.1)2 × 14 wires} ≈ 259 (can be used because< 300)

Use the EC2B control box under ambient temperature of –20 to +50°C. If thecontrol box is exposed to direct sunlight and the surface temperature may rise
above 50°C, provide a shade to keep the surface temperature below 50°C.

➁ Apply 10A to 1 circuit, 2A to the remaining 7 circuits:

See the table below for the allowable operating current when applying current
evenly to each control box.

Major heat sources comes from the wiring which is connected to the control
box. Therefore, not only the operating current but wiring conditions (size, no. ofwires, no. of wire bundles) may cause temperature rise. When wiring, observe
the following conditions.

*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 number of wires per bundle may need to be further reduced dependingon the wire size, lead-in fitting, or conduit size.
*2: The allowable current value (reference) when applying current evenly to all circuits of the maximum
number of circuits.

No displacement of the waterproof packing.
Wires are not caught between the joint surfaces.

When using the emergency stop switches on safety-related parts of the control

Installation

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, and 4 columns.

Maximum no. of wires per bundle: 16
Maximum operating current: 10A
When using the control box under an operating environment of 40°C minimum,
use a heat resistant cable of 70°C minimum.

Determine the operating current so that the total heat value of 1 wire bundle isbelow 300 [A2 × wires]. Also, when calculating the heat value, take the current
fluctuation (10%) into consideration. [calculation example: EC2B-41**B (8circuit)]Circuit Breakers

WiringWiring Construction

Observe the laws and regulations in each country concerning wiring construction.
Use cable wiring or metal conduit wiring for installation in hazardous locations. If
foreign objects or water may enter the box, install a sealing fitting near the cableentry of the box and seal the control box using a compound. Standard type control
boxes do not contain a terminal block. Wire the control units directly.
Stranded wire: 1.25 to 2.5 mm2, solid wire: ø1.2 to ø1.6 mm (AWG16 to 14). Do
not connect more than 2 wires to the same terminal.

Applicable crimping terminal
Ring and spade terminals cannot be used for EU2B control units with IP20
