Field wiring guidelines

Most field wiring on the unit is to be made on the terminal block
inside the switch box. To gain access to the terminal block,
remove the switch box service panel (door 2).
Cable tie mountings are provided at the bottom of the switch
box. Fix all cables using cable ties (field supply).
A dedicated power circuit is required for the backup heater.
Installations equipped with a domestic hot water tank (optional),
require a dedicated power circuit for the booster heater.
Please refer to the domestic hot water tank installation manual.
Secure the wiring in the order shown below.
Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely(see
figure 2).
Follow the electric wiring diagram for electrical wiring works (the
electric wiring diagrams are located on the rear side of doors 1
and 2).
Form the wires and fix the cover firmly so that the cover may be
fit in properly.
