Ziton ZP3, Installation Operation & Maintenance

Page: 9 / 239

Procedures in this manual should only be carried out by Trained Service Personnel.
The ZP3 panel is powered from a 230 volt AC primary supply and from a 24 volt DC battery backup
supply.
Primary Supply
Connection to the 230 volt AC primary supply (+10%: -15%), must comply with National wiring
regulations. The wiring shall be permanently connected to the building wiring through a 10 amp 3 core
cable, and a double pole 10 amp isolation switch.
Care must be taken to wire the primary supply to the correct terminals:
Live = Brown
Neutral = Blue
Earth = Green/Yellow
The earth wire must NOT be omitted.
The incoming mains fuse only breaks the live connection. Be aware that even when the fuse is
withdrawn, there remains dangerous potential on the incoming terminals. It should also be noted that
dangerous potentials can exist at other locations on the PC board even with mains and battery
disconnected.
Back-up Battery Supply
The back-up batteries, although at only 24 volts DC, carry enough charge to be dangerous.
Care must be taken when connecting batteries, or when working in the vicinity of the battery terminals,
to not accidentally cause a short circuit. In particular metallic tools or metallic watch straps, is causing
an accidental short circuit, can cause burns to the user.
