Daikin LRMEQ8AY1 [13/127] 2 procedure for incoming wiring
English 11
7-2 Procedure for Incoming Wiring
Route high-voltage wiring (power supply wiring, earth wires, and
warning/alarm/operation wiring) through wiring openings located
on the side or front of the unit (knock holes) or on the bottom
frame (knock holes).
Route low-voltage wiring (for remote operating switches) through
wiring openings (knock holes) located on the front of the unit or
through wiring intakes.
Note
Open the knock holes with a hammer or the like.
After knocking out the holes, we recommend you remove any
burrs and paint them using the repair paint to prevent rusting.
When passing electrical wiring through the knock holes, protect
the wiring with a conduit or bushings, making sure not to damage
the wiring.
If small animals might enter the unit, block off any gaps (hatching
parts) with material (field supply).
7-3 Procedure for Power Supply Wiring
Procedure for Power Supply Wiring
1 Power supply (3 phase 380~415)
2 Branch switch or overcurrent circuit breaker (earth leakage circuit
breaker)
3 Earth wire
4 Power supply terminal block
5 Mount insulation sleeves
6 Fix the power supply wiring for phases L1, L2, L3, and N, respec-
tively, with the provided clamp (1) to the resin clamp.
7 Fix the earth wire to the power supply wire (phase N) with the pro-
vided clamp (1).
8 Earth wire
Perform wiring so that the earth wire will not come in contact with
lead wires of the compressor. Otherwise, noise generated may
have a bad influence on other equipment.
9 Ground terminal
10 When two wires are connected to a single terminal, connect
them so that the rear sides of the crimp contacts face each
other.
Also, make sure the thinner wire is on top, securing the two
wires simultaneously to the resin hook using the accessory
clamp (1).
Power circuit, safety device, and cable requirements
A power circuit (see the following table) must be provided for con-
nection 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 circuit breaker.
When using residual current operated circuit breakers, be sure to
use a high-speed type (1 second or less) 200mA rated residual
operating current.
Use copper conductors only.
Use insulated wire for the power cord.
Select the power supply cable type and size in accordance with
relevant local and national regulations.
Specifications for local wiring are in compliance with IEC60245.
Use wire type H05VV when protected pipes are used.
Use wire type H07RN-F when protected pipes are not used.
Point for attention regarding quality of the public electric power
supply
This equipment complies with respectively:
EN/IEC61000-3-11
(1)
provided that the system impedance Z
sys
is
less than or equal to Z
max
and
EN/IEC61000-3-12
(2)
provided that the short-circuit power S
sc
is
greater than or equal to the minimum S
sc
value
at the interface point between the user’s supply and the public sys-
tem. It is the responsibility of the installer or user of the equipment to
ensure. by consultation with the distribution network operator if nec-
essary, that the equipment is connected only to a supply with respec-
tively:
Through-hole cover
