4 Installation and Wiring
2
Cover the Unit while wiring to prevent wire clippings from entering the Unit. If there is a dustproof
label on the top of the Unit, do not remote it before you wire the Unit.
(Remove the label or other covering after wiring has been completed to allow air circulation
needed for cooling.)

When solder-type connectors are being used, be sure not to accidentally short adjacent termi-
nals. Cover the solder joint with heat-shrink tubing.
Precautions for Safe Use
If the external power supply to an Output Unit has polarity, connect it with the correct polarity. If
the polarity is reversed, current may flow in the reverse direction and damage the connected
devices regardless of the operation of the Controller.
