4.5 Connecting the electrical wiring
DANGER: RISK OF ELECTROCUTION
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.
4.5.1 About electrical compliance
RZQG71_V1 + RZQG100~140_Y1
Equipment complying with:
▪ EN/IEC 61000‑3‑12 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 system.
▪ EN/IEC 61000‑3‑12 = 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.
▪ 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 the
minimum S
sc
value.

4.5.3 To connect the electrical wiring on the
outdoor unit
NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
1 Remove the service cover.
