Replacement Mains Interface Board
Replacement
The external mains cable should be rewired so that it enters the enclosure above the Mains terminal
a.
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
&
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

Switch ON the mains supply to the Unit and then connect the battery lead to the batteries and to
e.
connector P7 on the Replacement Mains Interface Board.
Using the [Test/Eng] menu at the control panel [Allocate] the loop circuit, on which the Interface unit is
f.
connected. The interface unit should then be tested to site specific requirements.
Close the enclosure door and lock it using the key.
