1. Type AWCI-M-AC 301.A :
Route the 230 V~ cables through one
cable entry, and the LV lead through
the other cable entry in the l.h. or r.h.
side panel.
Type AWO-M-AC 301.A :
Cut one entry in the sealing mat for
the 230 V~ cables and a second entry
for the LV lead. Route the cables from
below through the sealing mat.
2. Route the cables through the pre-fit-
ted retainers. Secure the LV lead and
230 V~ cables separately.
3. Danger
Cables/leads that are too
short can break off when the
control panel moves.
Secure the cables below the
front edge of the control panel
with a loop to the cable
bracket (see diagrams
above).
4. Push the connecting leads/cables
(LV lead < 42 V and control cable
230 V~) from the heat pump control
unit onto the distributor PCB in the
control panel (see page 69).
5. Route 230 V~ power cable through
cable entry and apply strain relief.
Make the power connection as
described on page 97.
Note
The 230 V~ power connection is pro-
tected against accidental contact with
a contact shield. This contact shield
can be sealed for power-OFF (if
required) (see page 99 and
page 100).
