2.4 Inputs and Outputs
SERIAL DATA CONNECTION: This connection is used to transfer data to the
PC via the serial adapter.
1- GENERATOR CONTACTOR: This output provides energy to the generator
contactor. If the generator phase voltage is outside of the programmed limits,
the generator contactor will be de-energized. In order to provide extra security,
normally closed contact of the mains contactor should be serially connected to
this output. Relay contact rating is 16A/250V-AC
2/3/4- L1/L2/L3: Connect the generator phases to these inputs. The generator
phase voltage upper and lower limits are programmable.
5- GENERATOR NEUTRAL: Neutral terminal for the generator phases.
6- MAINS NEUTRAL: Neutral terminal for the mains phases.
7/8/9- T-S-R: Connect the mains phases to these inputs. The mains voltages
upper and lower limits are programmable.
10- MAINS CONTACTOR: This output provides energy to the mains
contactor. If the voltage of at least one of the mains voltages is outside of the
programmed limits, the mains contactor will be de-energized. In order to
provide extra security, normally closed contact of the generator contactor
should be serially connected to this output. Relay contact rating is 16A/250V-
AC
11- AUXILIARY RELAY OUTPUT: This relay fulfills 4 different functions
following programming. Relay contact rating is 10A/28V-DC.
1) ALARM RELAY: If an alarm occurs, the relay will be activated. It will be
deactivated when the ALARM MUTE key is pressed.
1) ALWAYS remove the plug connectors when inserting
wires with a screwdriver.
2) ALWAYS refer to the National Wiring Regulations
when conducting installation.
3) An
appropriate
disconnection devices (e.g. automatic fuses) MUST be
provided as part of the installation.
4) The disconnection device must NOT be fitted in a
flexible cord.
5) The
building
appropriate short-circuit backup protection (e.g. a fuse
or circuit breaker) of High Breaking Capacity (HBC, at
least 1500A).
6) Use cables of adequate current carrying capacity (at
least 0.75mm
