CAUTION
To avoid compressor breakdown, do NOT charge more
than the specified amount of refrigerant.
Prerequisite:
Before charging refrigerant, make sure the refrigerant
piping is connected and checked (leak test and vacuum drying).
1
Connect the refrigerant cylinder to both the service port of the
gas stop valve and the service port of the liquid stop valve.
2
Charge the additional refrigerant amount.
3
Open the stop valves.
If pump down is needed in case of dismantling or relocating the
system, see
"11.3 To pump down" on page 22
for more details.

Connecting the electrical wiring
6.7.1
About connecting the electrical wiring
Typical workflow
Connecting the electrical wiring typically consists of the following
stages:
1
Making sure the power supply system complies with the
electrical specifications of the units.
2
Connecting the electrical wiring to the outdoor unit.
3
Connecting the electrical wiring to the indoor units.
4
Connecting the main power supply.
6.7.2
About electrical compliance
A AZQS125_Y1
Equipment complying with EN/IEC 61000312 (European/
International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public lowvoltage
systems with input current >16 A and ≤75 A per phase.).
AZQS140_Y1
Equipment complying with:
▪
EN/IEC 61000312
provided that the shortcircuit 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 system.
▪ EN/IEC
61000312
=
European/International
Technical
Standard setting the limits for harmonic currents produced by
equipment connected to public lowvoltage systems with input
current >16 A and ≤75 A per phase.
▪ 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 shortcircuit power S
sc
greater than or equal to the
minimum S
sc
value.

Precautions when connecting the
electrical wiring
INFORMATION
Also read the precautions and requirements in the
following chapters:
▪ General safety precautions
▪ Preparation
DANGER: RISK OF ELECTROCUTION
INFORMATION
More information about the legend and the location of the
wiring diagram of the unit can be found in
"12.5 Wiring
diagram" on page 30
.
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
For use of units in applications with temperature alarm
settings it is recommended to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for several
minutes during normal operation for "defrosting the unit", or
when in "thermostat stop" operation.
6.7.4
Guidelines when connecting the electrical
wiring
Keep the following in mind:
▪ If stranded conductor wires are being used, install a round crimp
style terminal on the tip. Place the round crimpstyle terminal on
the wire up to the covered part and fasten the terminal with the
appropriate tool.
