Electrical Connection
General
E
Compliance with the corresponding SEV,
EN, IEC, as well as the corresponding
VDE standards is required for the
electrical connection of the heat pump.
The connection specifications of the
local utility or electric company must be
complied with as well.
E
The power supply to the equipment must
be interrupted before each electrical
connection or service or maintenance
work. The upper cover on the equipment
must be removed for the electrical
connection. This requires unscrewing
four hexagonal screws on the rear
upper cover plate of the unit and re-
moving the cover by pulling towards
the top.
The power supply is carried out via the
inlet of the cable connection at the rear
side of the heat pump. All other neces-
sary control connections such as flow
monitor, frost protection, thermostat,
and temperature sensor are also at the
rear of the heat pump.
E
Power Supply to the Switchbox
The power supply for the heat pump
must feature a main switch or all-pole
cut-off switch with a contact distance
of at least 3 mm, as well as a 3-pole
circuit breaker with shared trigger for all
outer conductors. See technical data or
type plate on rear of heat pump for the
tripping current! The power cables must
have a cross-section that meets the
equipment output as well as locally
applicable rules and standards.
