Connecting Power Supply And Interunit Wiring; Precautions On Wiring Of Power Supply And Inter-Unit Wiring - Rotex RRLQ011CAV3 Manuel D'installation

■
As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.
CAUTION
Be sure to install the required fuses or circuit breakers.

14.2. Connecting power supply and interunit wiring

■
Secure the earth wire to the stop valve attachment plate so that
it does not slide.
■
Secure the earth wire to the stop valve attachment plate one
more time along with the electric wiring and the inter-unit wiring.
■
Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely.

When cables are routed from the unit, a protection sleeve for the
conduits (PG-insertions) can be inserted at the knockout hole.

When you do not use a wire conduit, be sure to protect the wires
with vinyl tubes to prevent the edge of the knockout hole from
cutting the wires.
■
Follow the electric wiring diagram for electrical wiring works
(delivered with the unit, located at the inside of the front plate).
■
Form the wires and fix the cover firmly so that the cover may be
fit in properly.
14.3. Precautions on wiring of power supply and
inter-unit wiring
■
Use a round crimp-style terminal for connection to the power
supply terminal board. In case it cannot be used due to
unavoidable reasons, be sure to observe the following
instruction.
1 Round pressure terminal
2 Cut out section
3 Cup washer
1 2 3
- Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
- When connecting wires of the same gauge, connect them
according to the below figure.
■
Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.
■
Over-tightening the terminal screws can damage the screws.
■
See the table below for tightening torques for the terminal
screws.

■
Refer to the installation manual attached to the indoor unit for
wiring of indoor unit, etc.
■
Attach an earth leakage circuit breaker and fuse to the power
supply line. (See figure 6)

3 Remote controller
■
In wiring, make certain that prescribed wires are used, carry out
complete connections, and fix the wires so that outside forces
are not applied to the terminals.
