B
Connect the 230 V AC mains cable of the first module
to the next module.
Fig. 65 Connecting several modules
B
Connect the free connector of the EMS bus
connecting cable to the first module (
Æ
fig. 64, [2]).
B
If more modules are used, the EMS bus connection for
the second module may be branched off from the first
module using the cable enclosed with the module
(
Æ
fig. 65 and 66).

INSTALLING AND CONNECTING FUNCTION MODULES
OUTSIDE THE BOILER
B
Install the module on the wall.
B
Make a sufficiently long EMS bus connection cable,
using a 2-core cable of 0.4 - 0.75 mm² and the
connector enclosed with the module (
Æ
fig. 66).
Important: Use the connector of the same colour as
the connections on the module.
B
Connect the EMS bus connection cable to the orange
connection of the terminal strip [1].

(connection colour orange)
B
Connect the other end of the EMS bus connection
cable to the first module (
Æ
fig. 65).
B
If more modules are used, the EMS bus connection for
the second module may be branched off from the first
module using the cable enclosed with the module.
B
Connect the EMS bus connection lead of the first
module to the next module (
Æ
fig. 65).
B
Make a sufficiently long 230 V AC mains cable, using
a 3-core cable of at least 0.75 mm² with an earthing
wire, the connector enclosed with the module and a
230 V AC earthed plug.
B
Connect the 230 V AC mains cable to the module
(
Æ
fig. 65). If more modules are used, the 230 V AC
supply to the next module can be branched off from
the previous module using the connector enclosed
with the module and a 3-core 0.75-mm² current cable
with an earthing wire.
B
Connect the 230 V AC supply cable of the previous
module to the next module (
Æ
fig. 65).
The module may have the letters RC or EMS
above the connection [1].
NOTE:
Pay attention to the polarity when using an
EMS bus connection cable..
B
Connect the wire from terminal 1 to ter-
minal 1 and from terminal 2 to terminal 2
(
Æ
fig. 65 and 66).
