# these components are packaged
separately.
b. If necessary, remove the door on the unit to ease
installation and remove the covers fitted over the mains
terminal.
c. Knockout the required cable entry points from the back box.
d. Mark the 3 fixing positions on the wall to which the unit is to
be mounted and secure the unit to the wall with suitable
fixings.
"
If the unit is to switch heavy non-mains loads,
then optional POWER RELAYS 19104-52 must be used.
The relays may be installed on the DIN rail inside the unit.
The relay unit must include a diode unit.
e. Terminate each cable at the entry point.
f. Fit the interface board inside the back box using the
screws provided.
g. Connect the incoming cable ends to the appropriate
terminals.
h. Connect the transformer secondary wires to terminal block
P7 on the interface board.
i. Place the batteries inside the back box, however do not
make the connection, this is done during commissioning
by the Servicing organisation.
j. Fit the cover over the mains terminal and battery
restraint bracket.
k. If removed, re-fit the door and earth lead.
"
The capacitor unit and the 22k Resistor must
be fitted to the end-of-line (EOL) of each circuit. Also
stick an EOL label on the last device in which the EOL
unit is fitted.
l. Close the door on the Unit using the Key.
m. Leave all outstanding parts and installation work to the
Servicing organisation.
External circuits
Power relay
Up to 4 relays can be fitted inside the interface unit on the DIN
rail.
¨
Octal relay operates from a 24V supply
¨
DIN rail mountable
¨
Relay coil resistance 470R
¨
Contacts rated 10A at 230Vac
