7.6.2 Electrical Installation
1) The five-core electrical supply cable for the output section
of the heat pump is fed from the heat pump meter via the
utility company blocking contactor (if required) into the
heat pump.
The mains cable is connected at the heat pump switch box
using terminals X1: L1/L2/L3/N/PE.
The enclosed mini-grip bag contains four links that have to
be connected to terminal X1 (L1-L10, L2-L20, L30-L3, N-
N0) as shown in the circuit diagram (see appendix). There is
no need for these links if two separate five-core supply ca-
bles are used (see appendix).
An all-pole disconnecting device with a contact gap of at
least 3 mm (e.g. utility company blocking contactor or
power contactor) as well as an all-pole circuit breaker with
common tripping for all external conductors must be in-
stalled in the power supply (tripping current and character-
istic in compliance with the device information).
ATTENTION!
!!
Only applies to the SIW 6TES:
Ensure the rotary field is clockwise when connecting the
mains cables (if the rotary field is not clockwise, the heat
pump will not work properly, is very loud and may cause
damage to the compressor).
Only applies to the SIW 8TES and SIW 11TES:
Ensure that there is a clockwise rotating field: With incorrect
wiring the starting of the heat pump is prevented. A
corresponding warning is indicated on the display of the heat
pump manager (adjust wiring).
2) The three-core electric supply cable for the heat pump
manager (heating controller N1) is fed into the heat pump.
Connection of the control line to the switch box of the heat
pump via terminals X2: L/N/PE.
Details on the power consumption of the heat pump are
listed on both the product information sheet and the type
plate.
The (L/N/PE ~230 V, 50 Hz) supply cable for the heat
pump manager must have a constant voltage. For this rea-
son, it should be tapped upstream from the utility blocking
contactor or be connected to the household current, as im-
portant protection functions could otherwise be lost dur-
ing a utility block.
3)
The utility blocking contactor (K22) with 3 main contacts (1/
3/5 // 2/4/6) and an auxiliary contact (NO contact 13/14)
should be dimensioned according to the heat pump output
and must be supplied by the customer.
The NO contact of the utility blocking contactor (13/14) is
looped from terminal strip X3/G to terminal X3/A1.
CAUTION! Extra-low voltage!
The contactor is installed in
the electrical distribution system. Mains cables for the
installed heaters must be laid and secured in accordance
with the valid standards and regulations.
4)
All installed electric cables must have permanent wiring.
5) The external sensor (R1) is connected to terminals X3/GND
(ground) and X3/R1.
7.6.3 Connecting an electronically
regulated circulating pump
Electronically regulated circulating pumps have high starting
currents, which may shorten the service life of the heat pump
manager. A coupling relay is therefore installed or must be in-
stalled between the output of the heat pump manager and the
electronically regulated circulating pump. This is not necessary
if the maximum permissible operating current of the heat pump
manager of 2 A and the maximum permissible starting current
of the heat pump manager of 12 A are not exceeded by the
electronically regulated circulating pump or a relevant approval
has been issued by the pump manufacturer.
ATTENTION!
!!
It is not permitted to connect more than one electronically
regulated circulating pump via a relay output.
