VUE2 150 P ЕС Comfo
Fig. 4. Control panel installation
1. 2.
The unit is designed for connection to 230 V / 50/60 Hz single-phase AC mains. The unit has a power cord with a Euro plug to connect
to a grounded IEC 60884-1 compliant socket. The power cord is pre-wired to X1 terminal block.
The external power input must be equipped with an automatic cut-out switch built into the stationary wiring to disconnect all the
power mains phases. The external switch position must ensure free access for quick power-off of the unit. The trip current must be not
less than the consumption current. The recommended automatic switch rated current is 1 A. The conductor cross section is 0.75 mm
2
. The
given conductor section value is tentative. In practice the conductor selection shall be based on the maximum permissible wire heating
depending on the wire type, its insulation, length and installation method (i.e. overhead, in pipes or inside the walls).
Use only copper core wires.
The unit must be properly grounded!
The unit enables the following external connection options (Х3 connector markings as shown on the label are given in round brackets
- Fig. 5):
- Automatic fire extinguishing system contact («PK»);
- Humidity relay (humidistat) contact or CO2 sensor contact («H»);
- «3-point control» air damper contact («Y-N, Y-L, Y-C»).
Upon connecting the automatic fire extinguishing system contact remove the jumper between the terminals Х3:1 and Х3:2 of
terminal block Х3. In this case a normally closed «dry» contact is used which opens the unit control circuit on fire-triggered actuation
from the central fire-fighting station cutting the unit power.
The humidistat (or СО2 sensor) is connected to the terminals Х3:3 and Х3:4 of the terminal connector Х3. The connection relies on a
normally closed «dry» contact. Once closed the unit switches to maximum speed.
The air damper actuator is connected to the terminals Х3:5, Х3:6 and Х3:7 of terminal block Х3. The same contacts can be used for
parallel connection of one more damper. Any extra contacts are connected according to the wiring connection diagram (Fig. 5).
CONNECTION TO POWER MAINS
THE POWER MAINS CONNECTION SHALL ONLY BE PERFORMED BY QUALIFIED PERSONS AFTER CAREFUL STUDY
OF THE PRESENT USER’S MANUAL.
THE UNIT IS ONLY INTENDED FOR AC MAINS SUPPLYING THE VOLTAGE COMPLIANT WITH THE TECHNICAL
PARAMETER TABLE. CHECK THE CABLE FOR CHOKING.
DO NOT SWITCH ON THE UNIT IF THE CABLE IS DAMAGED. NEVER UNPLUG THE UNIT FROM THE SOCKET WITH
WET HAND OR BY HOLDING THE ELECTRIC CABLE.
DISCONNECT THE UNIT FROM THE POWER SUPPLY PRIOR TO ANY WORK ON THE UNIT!
THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE STATED ON THE RATING PLATE.
ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY.
