HK 200M
5 Electrical connections
General information
The entire electrical equipment, apart from outdoor
temperature sensors, room sensors, and current in-
tensity meters, has been connected according to fac-
tory settings.
• Disconnect the indoor module before performing
tests of electrical system insulation in the build-
ing.
• If the building is equipped with a differential
switch, HK 200M must be equipped with a
separate switch.
• The diagram of indoor module connections can
be found in section „Diagram of electrical connec-
tions”.
• Do not lay communication and signal cables to
external contacts near high-voltage cables.
• Minimum cross-section of communication and
signal cables to external contacts must total 0.5
mm² with the length of up to 50 m, for example
EKKX or LiYY, or similar.
• Minimum cross-section of power supply cables
must total 0from 2.5 mm² to 4 mm².
• For cabling in HK 200M, use cable passes UB1
and UB2 (as marked in the drawing). In UB1 and
UB2, cables are input through the entire indoor
module from the back wall towards the front wall.
IMPORTANT
As long as the heating circuits have not been fi lled with
the heating medium, and if the central heating system
has not been vented, the switch (SF1) in SMO cannot
be set in positions „ I
” or „ ”. Otherwise, the tempera-
ture limiter, thermostat and fl ow-through heater can be
damaged.

IMPORTANT
The electrical installation and maintenance service
must be performed under the supervision of a qualifi ed
power technician with relevant qualifi cations. Before
starting any maintenance works, power supply must
be cut off using an automatic switch. The electrical in-
stallation and cabling must be executed according to
applicable regulations.
IMPORTANT
If the power supply cable is damaged, it can only be
replaced by authorised service, its technician, or other
qualifi ed person, to avoid danger or damage.
