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. ALSO MAKE SURE THAT THE
ALARM INDICATOR CABLES ARE DISCONNECTED.
NON-COMPLIANCE WITH THE ABOVE INSTRUCTIONS
CAN LEAD TO INJURY OR DEATH BY ELECTROCUTION.
The electrical installation must be performed by a fully qualied electrician, and in accordance with local
electrical standards and the wiring diagram corresponding to the unit model.
Any modication made without our consent will void the unit’s warranty.
The power supply cable section must be sufcient 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. Power supply cable length.
2. Maximum current draw of unit in operation.
3. Maximum current draw of unit at start-up
4. Installation method of power supply cables.
It is recommended to provide short circuit protection by means of a type aM fuse or a circuit breaker with
high breaking capacity on the distribution board. Protection must be selected according to the current values
shown in § ELECTRIC SPECIFICATIONS, page 9
SE4942 SYSCW-AR 07R/09R AC Control Siemens POL423 230V 50Hz +/- 10%
SE4943 SYSCW-AR 07R/09R EC Control Siemens POL423 230V 50Hz +/- 10%
SE4958 SYSCW-AR 07R/09R EC Control Siemens POL636 230V 50Hz +/- 10%
The power supply must be protected by an FFG mains circuit breaker.
All the electrical installations and wiring associated with this equipment must comply with local installations
regulations.
Connection to the terminals N, L and .
² L : phase
² N : neutral
² : P-E ground
13.1.3. PRESSOSTATS SETTING
LP : Low Pressure xed setting: 0.5 bar (7.25 PSI) reset at 1.5 bar (21.7 PSI)
HP : High Pressure xed setting: 18 bar (260 PSI) reset at 13 bar (190 PSI)
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.
