The KOMFORT EC DW600-2 / EC DW1000-4 / EC DW2000-2 units are
rated for connection to single-phase alternating current power mains 230 V /
50-60 Hz via insulated, durable and heat-resistant conductors (cables, wires)
with a matching cross section not less than 2.5 mm2. The wiring diagram is
shown in Fig. 14. The functional diagram is shown in Fig. 15.
The KOMFORT EC DW3800-2 unit is rated for connection to three-phase
alternating current power mains 400 V / 50-60 Hz via insulated, durable and
thermal-resistant cords (cables, wires) with respective cross section not less
than 2.5 mm2. The wiring diagram is shown in Fig. 16. The functional diagram
is shown in Fig. 17.
The above cross section is for reference only. The applicable cable must be
selected in consideration of the maximum wire temperature depending on
the wire and insulation type, the maximum current, the lead wire length and
its installation method. Use copper wires only.
The unit must be grounded in compliance with the valid electrical
standards of the user country!
Connect all the control and power conductors in compliance with the
terminal marking and polarity!
The rating plate with a terminal designation is placed inside of the
terminal box.
The terminal clamp marking corresponds to the marking on the wiring
diagram.
To connect the cables route those through the airtight electric lead-in in
the unit casing and connect the cables to the terminal block in the control
unit.
Cut power supply to the unit off by turning the automatic electric switch
QF to OFF position prior to any operations.
Take steps to prevent activation of the automatic switch before finishing
all the operations.

CONNECTION TO POWER MAINS
WARNING
Read the service instruction prior to any electric installations. Connection of the unit to power mains is allowed by a
qualified electrician only.
The rated electrical parameters are stated on the rating plate. No modifications of internal connections are allowed and will
result in void warranty.
Connect the unit only to power mains with valid electric standards.
Follow the respective electric standards, safety rules (DIN VDE 0100), TAB der EVUs. The house cabling system must be
equipped with a magnetic trip automatic switch at the external input. The contact gap on all poles must be at least 3 mm (VDE
0700 T1 7.12.2 / EN 60335-1).
The automatic switch trip current must be not below the rated current consumption (ref. Table 1). Enable quick access to an
automatic switch installation place.
