Danfoss DHP-L Opti Installation Guide

6 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 inter-
nally at the factory, for this reason electrical installation consists mainly of the connection of the power sup-
ply.
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).
