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.
