Electrical installation
[wiring diagram]
Danger of electric shock!
Electric shocks are highly dangerous!
Working at the electrical equipment of
the appliance is only allowed by
professional personnel observing the
current IEE regulations.
Isolate the electrical supply while
working at the electrical equipment of
the appliance and safeguard the
appliance against unintentional
connection to the circuit.
The gas supply and electrical cable
must be situated on the outside of the
radiation and combustion heat. Only use
heat-resistant cables near the tubes.
The power supply for the heater must be
flexible connected with Ölflex- or
silicone cable.
Electrical connection
Operation with MODBUS control
Power supply
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 33].
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 1.5 mm
2
Ölflex- or silicone cable
In order to disconnect the bluTek burner kit from
the electrical supply pull the plug out from IC
4000/1.
The 4-pin GDM plug for the power supply
bluTek burner kit is included in delivery
of the kit.
Fig 33: Electrical connection 4-pin plug
MODBUS communication
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 36].
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 45.
Electrical connection
exhaust gas collecting system
After conversion of the heaters to operation with
exhaust gas collection system they can be
electrically connected as described above.
Fig. 35 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“.
