Batteries
The compact requires one number 12V 5AH sealed lead acid batteries to provide backup power in the event of mains failure as
defined in BS5839pt9 for 24 hours standby and 3 hours operation when powered by normal mains supply.
For 72hour standby and 1 hour operation one number 12V 17AH battery is required, these will need to be fitted in an external
battery enclosure. The monitored charger in the Compact unit is capable of charging and monitoring these batteries.
Safety Information:
Sealed Lead acid batteries contain sulphuric acid which can cause burns if exposed to the skin. The low
internal resistance of these batteries means large currents will flow if they are accidentally short
circuited, causing burns and a risk of fire- exercise caution when handling batteries.
Power up Procedure:
Always apply mains power before connecting batteries. Do not commission the Compact unit
on batteries, as the high inrush current required by the power supply may rupture the battery fuse.
Always connect the Positive (Red +) terminal first, then the Negative (Black -)
To down power reverse the power up sequence.
