SystemAir AC-RSR105R32HEC, Installation And Maintenance Manual

Page: 29 / 79

Before connecting the supply lines, check that the voltage available is within the limits specified
(Refer to the § ELECTRIC SPECIFICATIONS, page 15).
Caution
KA1
Supplying the unit with a line with an unbalance exceeding the acceptable value results in
cancelling the warranty.

13. ELECTRICAL CONNECTIONS
WARNING
Before carrying out any work on the equipment, make sure that the electrical
power supply is disconnected and that there is no possibility of the unit being
started inadvertently.
Non-compliance with the above instructions can lead to injury or death by
electrocution.
The electrical installation must be performed by a fully qualified electrician, and in accordance with local
electrical standards and the wiring diagram corresponding to the unit model.
Any modification performed without our prior authorisation may result in the unit’s warranty being declared
null and void.
The power supply cable section must be sufficient to provide the appropriate voltage to the unit’s power
supply terminals, both at start-up and under full load operating conditions.
The power supply cable shall be selected in accordance with the following criteria:
1. Length and material of supply cables
2. Maximum intensity - the cables must support a suitable amperage under the unit's functioning
conditions.
3. Power supply cables’ installation mode.
Short circuit protection shall be provided. This protection shall comprise fuses or circuit breakers with high
breaking capacity, mounted on the distribution board.
If the local control includes an remote ambient temperature sensor and/or a set temperature adjustment
module, these shall be connected with shielded cable and shall not pass through the same conduits as the
power supply cables as the voltages induced may create reliability faults in the unit’s operation.
VERY IMPORTANT:
3~400V-50HZ
The SYSAER R32 is equipped as standard with a phase sequence and
cut-out controller located in the electrical box.
THE LED’s INDICATE THE FOLLOWING CONDITIONS:
Green LED = 1
Yellow LED =1
Power ON
The compressor rotation
direction is correct.
Green LED = 1
Yellow LED =0
Phase inversion or phase
absent (L1)
The compressor and the fans
do not start.
Green LED = 0
Yellow LED =0
Phase absent (L2 or L3)
The compressor and the fans
do not start.
Voltage differences between each phase do not have to exceed 2 %.
If the unbalance is inacceptable, call the distribution company to have this anomaly corrected.
