Replacement
a.
The external mains cable should be rewired so that it enters the enclosure above the Mains terminal
block on the
Replacement Mains Interface Board
, this ensures there is segregation between mains and
extra low voltage cables. Also, each unused cable entry point must be fitted with a plastic bung.
b.
Fit the
Replacement Mains Interface Board
on a carrier into the enclosure
o
using the screws supplied.
&
Ensure the board fixing screws are securely fitted as they form part of an earth continuity path to
the metal enclosure, this is necessary for electrical safety and for EMC compliance.
c.
Reconnect the external wiring to the terminal blocks
p
and
q
on the
Replacement Mains Interface
Board
.
d.
Check and ensure the correct End Of Line units are fitted for the respective Zone and Sector circuits.
e.
Switch ON the mains supply to the Unit and then connect the battery lead to the batteries and to
connector P7 on the
Replacement Mains Interface Board
.
f.
Using the
[Test/Eng]
menu at the control panel
[Allocate]
the loop circuit, on which the Interface unit is
connected. The interface unit should then be tested to site specific requirements.
g.
Close the enclosure door and lock it using the key.
