FINISH
Aluminium / RAL9005 black fine texture
FAIL ALARM RELAY CONTACT SET (OPTIONAL)
Volt-free form C relay contact set for signalling of a fault alarm condition. The relay contacts de-energise 60 seconds after a fault occurs. The over voltage protection shutdown alarm de-energises the contacts instantly.
TERMINATION
AC input and DC output:
Connections terminate to rising clamp screw terminals and will accept 6.0mm2 stranded cable.
Optional fail alarm:
Connections terminate to rising clamp screw terminals and will accept 2.5mm2 stranded cable.
Connector ‘C1’ (signals):
Pins 7 and 8 should be linked when the charger should also function as a PSU.
NOTE: Reverse battery and battery disconnected alarms are disabled in PSU mode.
The remaining pins are for expansion modules, communication interfaces, firmware upgrade, etc and should not be used.
