Caution for Mounting

This instrument is intended to be used under the following environmental
conditions (IEC61010-1)]: Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to122 ) (No icing)• An ambient non-condensing humidity of 35 to 85 %RH (Non-condensing)• No large capacity electromagnetic switches or cables through which large
current is flowing• No water, oil or chemicals or the vapors of these substances can come into
direct contact with the unit
• Take note that the ambient temperature of this unit – not the ambient
temperature of the control panel – must not exceed 50 (122 ) if mounted
through the face of a control panel, otherwise the life of electronic components(especially electrolytic capacitors) may be shortened.

Mounting and Removal of the Unit

CautionAs the case of the PCA1 is made of resin, do not use excessive force while tightening screws, or the mounting brackets
could be damaged. The torque should be 0.12 N•m.
Mounting of the Unit
Mount the controller vertically to the flat, rigid panel to ensure it adheres to the Drip-proof/Dust-proof specification (IP66).
If the lateral close mounting is used for the controller, IP66 specification (Drip-proof/Dust-proof) may be compromised, and all warranties
will be invalidated.
Mountable panel thickness: 1 to 8 mm(1) Insert the controller from the front sideof the control panel.
(2) Attach mounting brackets by the holes
top and bottom of the case, and secure
the controller in place with the screws.
The torque should be 0.12 N•m.

UP

Removal of the Unit
(1) Turn the power to the unit OFF, anddisconnect all wires.
(2) Loosen the screws of the mounting
brackets, and remove the mounting brackets.
(3) Pull the unit out from the front of the control panel.

Warning

Turn the power supply to the instrument off before wiring or checking.
Working on or touching the terminal with the power switched on may result in severe injury or death due to electrical shock.

Caution• Do not leave wire remnants in the instrument, as they could cause a fire or malfunction.
• Use the solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the instrument.
• The terminal block of this instrument is designed to be wired from the left side. The lead wire must be inserted from the left side of
the terminal, and fastened with the terminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw when tightening, the terminal screwor case may be damaged. The torque should be 0.63 N･m.
• Do not pull or bend the lead wire on the terminal side when wiring or after wiring, as it could cause malfunction.
• This instrument does not have a built-in power switch, circuit breaker and fuse. It is necessary to install a power switch, circuit
breaker and fuse near the controller. (Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For the grounding wire, use a thick wire (1.25 to 2.0 mm2).
• For a 24 V AC/DC power source, ensure polarity is correct when using direct current (DC).
• Do not apply a commercial power source to the sensor which is connected to the input terminal nor allow the power source to comeinto contact with the sensor.
• Use a thermocouple and compensating lead wire according to the sensor input specifications of this controller.
• Use the 3-wire RTD according to the sensor input specifications of this controller.
• For DC voltage input, (+) side input terminal number of 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC differs from that of 0 to 10 mV DC, -10
to 10 mV DC, 0 to 50 mV DC, 0 to 100 mV DC, 0 to 1 V DC.
• When using a relay contact output type, externally use a relay according to the capacity of the load to protect the built-in relay
contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires.
