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).
WARING
Switch off all power including the unit power supply and backup heater and domestic hot water tank power supply (if applicable)
before removing the switch box service panel.

Fix all cables using cable ties.

A dedicated power circuit is required for the backup heater.

Installations equipped with a domestic hot water tank (field supply) require a dedicated power circuit for the booster heater.
Please refer to the domestic hot water tank Installation & Owner's Manual. Secure the wiring in the order shown below.

Lay out the electrical wiring so that the front cover does not rise up when doing wiring work and attach the front cover securely.

Follow the electric wiring diagram for electrical wiring works (the electric wiring diagrams are located on the rear side of door 2.

Install the wires and fix the cover firmly so that the cover may be fit in properly.
Do not overpass the maximum power allowed, which varies, according to the type of signal.
Lay the cables far from power cables or cables having a different tension and that are able to emit electromagnetic disturbances.
Do not lay the cable near devices which can generate electromagnetic interferences.
Do not lay the cables parallel to other cables; cable crossings are possible, only if laid at 90°.
Connect the screen to the ground, only if there aren’t disturbances.
Guarantee the continuity of the screen during the entire extension of the cable.
Respect impendency, capacity and attenuation indications.
