Electrical connection
Operation with MODBUS control
Route a flexible 3-wire electrical connection
cable [max. 3 x1.5 mm
2
] for power supply burner
kit to the four-pin plug and connect the cable
according to connecting scheme [Fig 29].
Connect 4-pin GDM socket with housing plug on
burner control unit IC 4000/1 of the burner kit.
The power supply for the heater must be flexible
with maximal wire cross-section of 3x 1.5mm
2
Ölflex- or silicone cable
In order to disconnect burner kit from the
electrical supply pull the plug out from IC 4000/1.
The 4-pin GDM plug for the power supply
burner kit is included in delivery of the
kit.
Route a flexible 3-wire MODBUS cable
[max 3x 0.5 mm
2
] for the Modbus connection into
the free cable gland of the burner control unit
IC 4000/1 and connect it according to the
connection diagram [Fig 30].
Maximum length between junction box MODBUS
and connection burner control unit IC 4000/1
may be 0.5 m.
At the of each MODBUS communication circuit a
terminal resistance 120
must be set on the
relevant burner control unit IC 4000/1. Resistor is
already loosely plugged into each socket KN 8 of
the burner control unit IC 4000/1. This socket must
then be closed with the resistor.
The necessary MODBUS address assignment is
explained on page 38.

Electrical connection
exhaust gas collecting system
[herringbone system]
After conversion of the heaters to operation with
exhaust gas collection system they can be
electrically connected as described above.
Fig. 32 shows the wiring diagram between the
central control unit SchwankControl Touch control
and the peripherally required SchwankControl SAV
1 extension kit and SAV fan monitoring kit.
Further information and wiring schemes for
more different electrical connection
options [e.g. multi-zone operation,
grouping of several central control units
SchwankControl Touch,…] can be found
in „Electrical Compendium“
