Connecting Power Wire And Transmission Wires; Power Circuit And Cable Requirements - Panasonic U-5ML5DPQ Installation Manual

11.4. Connecting power wire and transmission wires

Let the power wire (including ground wire) go through the power
outlet port on either the front, side or back of the outdoor unit.
Let the transmission wires go through the cable outlet port, pipe
outlet port or knock out hole on either the front, side or back of
the outdoor unit. (See figure 9).

Precautions when knocking out knockout holes
To punch a knock hole, hit on it with a hammer.
After knocking out the holes, we recommend you paint the
edges and areas around the edges using the repair paint to
prevent rusting.
When passing electrical wiring through the knock holes, remove
any burrs from the knock holes and wrap the wiring with
protective tape to prevent damage.
If there is any possibility that small animals enter the system
through the knock holes, plug the holes with packing materials
(to be prepared on-site).

Use a power wire pipe for the power wiring.
Outside the unit, make sure the low voltage electric
wiring (i.e. for the remote control, between units, etc.)
and the high voltage electric wiring do not pass near
each other, keeping them at least 50 mm apart.
Proximity may
malfunctions, and breakage.
Be sure to connect the power wiring to the power
wiring terminal block and secure it as described under
"11.4. Connecting power wire and transmission wires"
on page 15.
Inter-unit wiring should be secured as described in
"11.4. Connecting power wire and transmission wires"
on page 15.
• Secure the wiring with clamps so that it does not touch
the piping.
• Make sure the wiring and the electric box lid do not
stick up above the structure, and close the cover
firmly.

11.5. Power circuit and cable requirements

A power circuit (see table below) must be provided for connection of
the unit. This circuit must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage breaker.

relevant local and national regulations.
Wire size must comply with the applicable local
and national code.
Specifications for local wiring power cord and
branch wiring are in compliance with IEC60245.
In connecting the power cable to the power terminal block,
securely clamp the cable as shown in figure 9.
After finishing the electric work, confirm that each electric
part and terminal inside the electric parts box is connected
securely.
