Installation & Configuration Manual
11 Powering up the SPC controller
The SPC controller has two power sources, the mains supply and the integral
standby battery. A qualified electrician should undertake connection to the mains
and the mains supply should be connected from a spur that can be isolated. See
Page [âž™ 346] for full details of conductor sizes / fuse ratings etc.
The SPC should be powered from the mains first and then the internal standby
battery. For compliance to EN only one battery should be fitted of the appropriate
capacity.
11.1 Powering from battery only
It is recommended that when powering a system from battery only, the battery
should be in a fully charged state (>13.0 V). The system will not power up when
using a battery with less than 12 V and no mains is applied.
The battery will continue to power the system until deep discharge level (10.5 V to
10.8 V) has been detected. The time duration that the system will hold up on
battery will depend on the external loading and Ah rating of the battery.
