Maintenance
Dry Contact Relay (option)
The charger requires no maintenance other than the occasional wipe down to remove dust
that could reduce its ability to dissipate heat, and carefully blow air through the cooling vent
to remove any dust buildup on it or inside the unit.
The charger can be fitted with a 1 amp dry contact relay that can be used to indicate charger
status to a monitoring system. It has both a normally open and normally closed contact which
changes state depending on the presence of absence or charging voltage on the output of the
charger and is independent of the microprocessor. If the charger is producing voltage on the
output, the normally closed contact will be closed and there will be an electrical connection
between NC and COM. If the voltage on the output of the charger goes to zero, the contact
will change state. The Normally Open contact operates exactly in the reverse of the Normally
Closed contact.
