KOMFORT EC SKE270-1.5
The unit is rated for connection to single-phase alternating current power
mains 230 V / 50-60 Hz.
The unit is delivered ready to plug-in and is connected to power supply
via a pre-wired power cable with a euro plug.
In case of need to connect a longer cable follow the wiring diagram
below. The electric connections must be performed with insulated, durable
and heat-resistant cables, wires with a matching cross section.
While selecting the conductors with respective cross section consider
the wire type, the maximum permissible conductor heating temperature, its
insulation, length and layout.
Use copper wires only! The unit must be grounded in compliance with the
valid electrical standards of the user country!
The unit has extra electric connection options. Designation of the contacts
on the sticker of the X3 terminal block are enclosed in brackets, fig. 7:
-
PK contact
for connection of a fire extinguishing system
-
H contact
for connection of a humidity sensor or CO2 sensor
While connecting the automatic fire extinguishing system remove the
jumper between the X3:1 and X3:2 terminals of the X3 terminal block. In case
of fire a normally closed dry contact breaks the control circuit and cuts off
power supply to the unit.
Connect the humidity sensor or CO2 sensor to the X3:3, X3:4 terminals
of the X3 terminal block. If the sensor is activated, the normally opened dry
contact closes and switches the unit to maximum speed.
Connect extra contacts according to the electric wiring diagram, fig.
7. Route the wires through the electric lead-in in the upper part of the air
handling unit.
