REMKO RXT xxx DC - Manual (Page 22)

All electrical installation work
is to be performed by specialist
companies. Disconnect the
power supply when connecting
the electrical terminals.
! CAUTION
Electrical connection
For RXT 351-1401DC units,
a protected mains supply cable and
control cable should be connected
to the outdoor component and
indoor unit respectively.
NOTE
We recommend using
shielded cable for the control
lines.
Connecting the indoor unit
The unit requires a six-wired
control cable from the indoor unit
to the outdoor component.
■
We recommend that a mains/
repair switch be installed near
the outdoor component.
■
Voltage is supplied to the
outdoor component, the indoor
unit is supplied through the
control cable between the
outdoor component and the
indoor unit.
■
The terminal blocks for making
the connections are located
inside the unit.
■
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.
Make the connection as follows:
1. The connection terminal block
is located inside the unit on the
right-hand side (Fig. 12).
2. Connect the unit to the
control cable from the outdoor
component.
See “Electrical connection
diagram”.
3. Re-assemble the unit.
Check all plugged and clamped
terminals to verify they are
seated correctly and make
a permanent contact. Tighten
as required.
