4.3 Commissioning
4.3.1 Preliminary checks
Before connecting the mains power to the panel, the following must be checked:
1
Verify that the earth lead terminal is connected to the safety earth terminal og the mounting plateand ensure that a proper earth is connectedto mains earth
block terminal, check if the EARTH FAULT jumper is fitted.
2
Check that the EOL devices are correctly terminated in the zone input and sounder
output terminals and no external wiring terminations have been made.
3
Apply power (main power supply and batteries) as indicated below and make a reset
from level 2 (user access). Check if the control panel is on stand-by.
4.3.2 Mains Power
Disconnect the service breaker on the distribution board.
Before applying mains power
to the control panel, make sure that you carry out the following
checks and procedures:
Make sure that main supply wiring is brought into the cabinet separated from low voltage wiring.
Prepare the mains supply wiring for connection as follows:
Check that
differential circuit breaker is disconnected
. For safety reasons, remove the mains
fuse and keep and put it away in a safe place until all the wiring connections are finished.
i
Remove the outer cable sheath to provide sufficient slack, approximately 80mm, in the
wiring to assist termination.
ii
Form each wire in a ‘pigtail’ before taking it to its termination point. Route the L and N
wires such that there is separation from the safety earth.
.
iii
Connect the L and N wires directly to the MTB (left and right terminals, respectively).
The safety earth
(
)
wire must be terminated at the central terminal. See drawing on
the right
.
Note:
Terminals accept 1 to 2.5mm2 cables.
