8. Relay Box Installation
Before installing the Relay Box, replace the control box and wiring as they were.
* Insert the cable connectors until they click.
Attach the Relay Box to the pillar on the left side of the unit and the plate under the control box, using the three supplied M5 screws.
The screw labeled X in the figure is there to keep the Relay Box from falling. When performing maintenance, only loosen (but not
remove) this screw.
Remove the cable strap attached to the pillar. Then, attach the removed cable strap to the hole on the bending parts of the Relay Box
cover.
●
Secure the cables and lead wires in place.
(Referring to the electrical diagram below, connect the lead wires.)
