4.2 Remote Alarms Interface Board (4590056 Q)
4.2.1 Alarm outputs
The Remote Alarms Interface board is fitted in the right hand side of the unit as shown in figure 4-2
and is connected (piggy back style) directly via connector X1 onto the Interface Board connector X2.
This board therefore can only be used in conjunction with the Interface Board (4590055P).
The Remote Alarms Interface board contains a number of relays driven by alarm signals generated
within the UPS, whose contacts provide a set of volt-free alarm outputs that are connected to terminal
blocks X2 and X3 as shown in figure 4-3. These outputs can be used to drive an external alarms
monitoring device.
Maximum contact rating on M1 terminals
50 Vcc @ 1 Amp.
Note: When using the above contacts for remote alarm
annunciation, the power supply for the remote
indicators must be provided from an external power
source. Under no circumstances should the UPS
internal low voltage supplies be used for this purpose.
