Leading power line and transmission line

Be sure to let the power line and the transmission line pass
through a conduit hole.
Lead the power line from the upper hole on the left side plate,
from the front position of the main unit (through the conduit hole
of the wiring mounting plate) or from a knock out hole to be
made in the unit's bottom plate. (See figure 22)

Precautions when knocking out knockout holes
To punch a knockout 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 knockout holes,
remove any burrs from the knockout hole edges. Wrap the wiring
with protective tape in order to prevent damage to the wires, put
the wires through field supplied protective wire conduits at that
location, or install suitable field supplied wire nipples or rubber
bushings into the knockout holes.

3 If there are any possibilities that small animals enter the system
through the knockout 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 weak 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 cause electrical interference,
malfunctions, and breakage.
Be sure to connect the power wiring to the power
wiring terminal block and secure it as described under
"8.7. Field line connection: power wiring" on page 13.
Inter-unit wiring should be secured as described in
"8.6. Field line connection: transmission wiring" on
page 12.
• Secure the wiring with the accessory clamps so
that it does not touch the piping and no external
force can be applied to the terminal.
• Make sure the wiring and the electric box lid do not
stick up above the structure, and close the cover
firmly.
