Electrical Installation

DANGER! Electrical voltage! The terminal blocks are live and can be highly dangerous due to the risk of
electric shock. All power supplies must be isolated before electrical installation is started. The heat pump
is connected internally at the factory, for this reason electrical installation consists mainly of the
connection of the power supply.
Caution! Electrical installation may only be carried out by an authorized electrician and must follow
applicable local and national regulations.
Caution! The electrical installation must be carried out using permanently routed cables. It must be
possible to isolate the power supply using an all-pole circuit breaker with a minimum contact gap of 3
mm. (The maximum load for externally connected units is 2A).
