Relay interface card contact information
The relay contacts must not be galvanically connected to any mains-connected circuits. Do not use +12VDC
(Pin13) of the relay interface card for any power supply purposes for external devices. Reinforced insulation
to the mains is required for equipment and cables attached to these connections. Relay contacts are rated
for maximum 1A/30VAC or 200mA/60VDC. All relay outputs are galvanically isolated from the other circuits
of the UPS.
BestDock Relay Interface Card shutdown function
Normally-closed (NC)/-open (NO) connection state when the relay interface card is not powered. **The shutdown pin (15) needs minimum of 5 sec-
onds high level signal (connection to +12VDC) to perform the UPS shutdown. Shutdown function is not available for 9125, 9330, and 9340.
