Procedure For Incoming Wiring; Procedure For Power Supply Wiring - Daikin LRLEQ5AY1 E Manual De Instalación

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).

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:
(1)
EN/IEC61000-3-11 provided that the system impedance Z
less than or equal to Z and
max
(2)
EN/IEC61000-3-12 provided that the short-circuit power S
greater than or equal to the minimum S
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:
