Electric connection
5.2 Connecting voltage cable
- Connecting shall be done in accordance with scheme given
in the Figure no. 7.
- Neutral (zero) guide is connected on corresponding line
clamp (N). The line clamp of zero ducts is in blue colour.
- To connect voltage cable there are planned line clamps of
corresponding boiler power.
- To connect room thermostat and circulation pump there are
planned ancillary working clamps.
WARNING! When connecting phase guides it is
mandatory to tight bolts in line clamps to achieve as
better as possible connection between guide and
clamp.
- Guides for grounding should be connected in middle clamp labeled with
grounding symbol. Line clamp of device grounding duct is in
green colour.
- When connecting voltage cable on the boiler, carefully pull the
cable to the line clamps and take care not to damage cables
inside the device.
NOTE: Room thermostat is to be connected on line
clamps.
DANGER! If good connection between guide and
clamp is not good it can make uncontrolled clamp
warming and its failure.
NOTE! Only professional and qualified person
for such jobs must execute this device
connecting.

It is necessary to apply room thermostat with
non-voltage contacts, for clamps predicted
for connecting has the voltage of 230V, 50Hz.

Recommendation: Connect room thermostat
with seven days programming achieving
comfortable heating and energy savings.
