ERHQ011~W1 + ERLQ011~W1

Outdoor unit for air to water heat pump

4PW54249-1

When cables are routed from the unit, a protection sleeve for the
conduits (PG-insertions) can be inserted at the knock-out hole.
(See figure 3)

When you do not use a wire conduit, be sure to protect the wires
with vinyl tubes to prevent the edge of the knock-out hole from
cutting the wires.

Follow the electric wiring diagram for electrical wiring works.

Form the wires and fix the cover firmly so that the cover may be
fit in properly.

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.

-

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)

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.
