General
■
Electrical installation and wiring must be carried out
in accordance with national provisions.
■
Disconnect JÄSPI Inverter Nordic before insulation
testing the house wiring.
■
If a miniature circuit breaker is used, this must have at
least triggering characteristic "C". See section "Technic-
al specifications" for fuse size.
■
If the building is equipped with an earth-fault breaker,
JÄSPI Inverter Nordic should be equipped with a sep-
arate one.
■
JÄSPI Inverter Nordic must be installed via an isolator
switch. The cable area has to be dimensioned based
on the fuse rating used.
The RCD should have a nominal tripping current of no
more than 30 mA. The incoming supply must be 400V
3N~ 50Hz via an electrical distribution unit with fuses.
For 230V~ 50Hz, the incoming supply must be 230V~
50Hz via distribution box with fuses.
■
The routing of cables for heavy current and signals
should be made out through the cable glands on the
heat pump's right-hand side, seen from the front.
■
The communication cable must be a screened cable
with three conductors.
■
Connect the charge pump to the indoor module/con-
trol module. See where the charge pump must be
connected in the installation manual for your indoor
module/control module.
NOTE
Electrical installation and any servicing must
be carried out under the supervision of a qual-
ified electrician. Disconnect the current using
the circuit breaker before carrying out any ser-
vicing.
NOTE
Check the connections, main voltage and phase
voltage before the product is started, to pre-
vent damage to the heat pump electronics.
NOTE
The live external control must be taken into
consideration when connecting.
NOTE
If the supply cable is damaged, only Kaukora,
its service representative or similar authorised
person may replace it to prevent any danger
and damage.
NOTE
Do not start the system before filling up with
water. Components in the system could be
damaged.
NOTE
To prevent interference, sensor cables to extern-
al connections must not be laid close to high
voltage cables.
