9.8 Preparing the electrical installation

WARNING Risk of electrocution!

Carry out all electrical connection and installation work

in accordance with national and regional regulations.

WARNING Risk of electrocution!

The connection to the power supply must be in the form

of a permanent connection. The appliance must be able

to be separated from the power supply by an isolator

that disconnects all poles with at least 3 mm contact

separation. This requirement can be met by contactors,

isolators, fuses, etc.

Material losses

The specified voltage must match the mains voltage. Ob-

serve the type plate.

Material losses

Provide separate fuses for the 3 power circuits (for the

appliance, the electric emergency/booster heater and the

control unit).

Always connect "L" for the heat pump and the control unit to

the same phase.

Where required, you can install our starting current limiter with

25 A for the WPL 10 AC (see "Additional accessories").

Route cables with the following cross-sections in accordance

with the respective fuse rating:
