7.4 Electrical Connection

The following electrical connections must be established on the
heat pump:
 Connection of the control wire to terminals X1: L/N/PE in the
control box of the heat pump.
 Connection of the load wire to terminals X5: L1/L2/L3/PE in
the control box of the heat pump.
 Connection of the brine pump (to be supplied by the cus-
tomer) to terminal PE and pump contactor K5: 2/4/6 on the
control panel of the HP.
All electrical components required for the operation of the heat
pump are located in the control box.
For more detailed instructions concerning the connection and
functioning of the heat pump manager (e.g. the supplied external
wall sensor) please refer to the enclosed operating manual of the
manager.
An automatic circuit-breaker with simultaneous tripping of all ex-
ternal conductors is to be provided in the load power supply. The
circuit-breaker must be an all-pole disconnect device with a con-
tact gap of at least 3 mm. The same applies to any additional dis-
able contactors that may be required, e.g. during shut-off periods
imposed by the utility company. The required cross-sectional
area of the conductors is to be selected according to the power
consumption of the heat pump, the technical connection require-
ments of the relevant utility company and all applicable regula-
tions. Power consumption data of the heat pump is provided in
the product literature and on the nameplate. The terminals are
designed for a max. conductor cross-section of 35 mm².
ATTENTION!
The clockwise phase sequence must be observed when connecting the
load lines (the heat pump will deliver no output and will be very noisy
when the phase sequence is incorrect).
The power cable must be run through the guide tubes, inserted
into the side of the control box and secured by means of the
strain relief.

8.1 General




Extra-low voltage is applied to controller terminals N1-J1 to N1-
J11; N1-J24 and terminal strip for G/24 V AC; G0/0 V AC and
GND. If, due to a wiring error, the line voltage is mistakenly con-
nected to these terminals, the heat pump manager will be de-
stroyed.

connection
During start-up, observe the respective national safety regu-
lations and the applicable VDE safety regulations, particu-
larly VDE 0100, as well as the technical connection require-
ments of the utility companies (EVU) and network operators!
To ensure that the frost protection function of the heat pump
works properly, the heat pump manager must remain con-
nected to the power supply and the flow must be maintained
through the heat pump at all times.
The switching contacts of the output relay are interference-
suppressed. Therefore, depending on the internal resist-
ance of the measuring instrument, a voltage can also be
measured when the contacts are open. However, this will be
much lower than the line voltage.
