Relay Card (URC005)
The intelligent slot on the UPS unit may accept either the Relay card or the Network
card, not both. The Relay card is not supported in the 3-phase UPS units since these
units have built-in dry contact points. Follow the steps in the
section to install or remove the Relay card from the UPS unit.
CAUTION
! DO NOT TOUCH THE RELAY CARD WITHOUT PROPER ESD
PROTECTION.
The 12-pin relay card allows the user to monitor specific status on the UPS. The
predefined monitoring contact points on the relay card change state when the status in
the UPS changes state.
