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.
14.4. Specifications of standard wiring components
Only for AZQS*V1 + 125Y1:
Equipment complying with EN/IEC 61000-3-12
(1)
.
Only for AZQS140Y1:
Point for attention regarding quality of the public electric
power supply
This equipment complies with EN/IEC 61000-3-12
(1)
provided
that the short-circuit power S
sc
is greater than or equal to
1170 kVA at the interface point between the user's supply and
the public system.
It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
a short-circuit power S
sc
greater than or equal to 1170 kVA.
Above indicated value is the most stringent value. Refer to
databooks for specific product-data.
15. Test operation
15.1. Pre-run checks
Be sure to perform a test run.
Be sure to fully open the liquid-side and gas-side stop valves. If
you operate the unit with stop valves closed, the compressor will
break down.
Be sure to execute the first test run of the installation in cooling
mode operation.
Never leave the unit unattended with an open front panel during
test run.

CAUTION
Select all cables and wire sizes in accordance with
applicable legislation.
After finishing the electrical work, confirm that each
electric part and terminal inside the electric part box is
connected securely.
The earth leakage breaker must be a high-speed type
breaker of 30 mA (<0.1 s).

European/International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage systems
with input current >16 A and
≤
75 A per phase.
DANGER
Never leave the unit unattended during installation or
servicing. When the service panel is removed live parts
can be easily touched by accident.
INFORMATION
Note that during the first running period of the unit,
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates from
the compressor that needs elapse of a 50 hours run in
period before reaching smooth operation and stable power
consumption.
Items to check
Electrical wiring
Inter-unit wiring
Ground wire
Is the wiring as mentioned on the wiring
diagram?
Make sure no wiring has been forgotten and
that there are no missing phases or reverse
phases.
Is the unit properly grounded?
Is the wiring between units connected in
series correct?
Are any of the wiring attachment screws
loose?
Is the insulation resistance at least 1 M
Ω
?
- Use a 500 V mega-tester when
measuring insulation.
- Do not use a mega-tester for low-voltage
circuits.
Refrigerant
piping
Is the size of the piping appropriate?
Is the insulation material for the piping
attached securely?
Are both the liquid and gas pipes insulated?
Are the stop valves for both the liquid side
and the gas side open?
Extra refrigerant
Did you write down the extra refrigerant and
the refrigerant piping length?
