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