REMKO ATY 261 - Manual (Page 21)

Electrical connection
A protected mains supply and
control cable should be connected
to the outdoor component and
indoor unit respectively.
All electrical installation
work should be performed
by specialist contractors.
Isolate the voltage supply
when connecting the electrical
terminals.
CAUTION
■
We recommend that customers
install a main/repair switch
in the vicinity of the outdoor
component.
■
The terminal blocks for making
the connections are located at
the rear of the unit. When the
unit is installed, measurements
can be made from the front by
removing the cover.
■
If an optional condensation
pump is used in conjunction
with the unit, it may be
necessary to install an
additional relay with a higher
contact rating after the switch-
off contact on the pump to
switch off the compressor.
Connecting the indoor unit
Make the connection as follows:
1. Dismantle the front of the unit
as described in the chapter
"Installing the unit".
2. Select the cable cross-section
according to the relevant
standards.
3. Connect the mains supply to
the unit and the control cable
to the outdoor component
(see electrical connection
diagram).
4. Re-assemble the unit.
