5.10. Use of Warning Relay Interface (option)
This is an optional card (slot-mounted) that will manage 6 indication circuits with isolated
contacts carrying information on the status of the UPS. The maximum voltage that can be
applied to the contacts is 24 VDC, and the maximum current 500 mA.
Relay contacts can be set individually for NO (default) or NC operation, and
programmed selectively for customized monitoring of the UPS.
If requested, the UPS can also be switched off utilizing a remote external shutdown
contact. The command is acknowledged when the contact is made and held for 3
seconds (default), whereas the external contact must be made between the common
and input pins.
The external contact MUST be dedicated and voltage-free, so as not to
cause permanent damage to the UPS.
The shutdown input can be configured alternatively as a battery test input.
