IMPORTANT SAFETY NOTICES
The mains power point to which the system is connected should remain easily
accessible in case the system needs to be powered down.
Note: To power down the system when a Battery Back Up module and battery
are connected, both the mains power and the battery must be disconnected. Even
if the mains power is switched off, hazardous voltages are still present if the
battery remains disconnected.
After installation of the system or changes to the wiring configuration, the access
cover should always be replaced for safety reasons.
The battery recommended for use with the system is as follows -
• Sealed Lead Acid type
• 12 Volt
• 6 or 7 Ampere hour
• “Faston Tab 187” terminals.
If the battery is to be housed in the plastic battery enclosure, it should be no
larger than
151 mm (L) x 65 mm (W) x 97.5 mm (H).
The battery cable supplied with the system contains a 5 Amp fuse in the Positive
(red) wire.
If other cables are to be used, a 5 Amp fuse must be inserted in series with the
Positive wire.
At the system end, the battery cables should be stripped back 7 mm and fully
inserted into the connector (J2) to ensure that the conductors are not accessible.
