TECHNICAL DATA

®
– MV EC
If the temperature monitoring system trips frequently, this is a sign that a possible fault has occurred� The sys-
tem must not be operated and it must be investigated by a qualified electrician�
Control of several EC-fans with a potentiometer
In order to control several EC fans via the setpoint input "0-10V", the 10 V DC voltage source must provide the
sum of all setpoint input load currents.
m
Parallel connection of +10 V DC supply of several EC fans is not permitted!
Depending on the type several EC-fans can be controlled with the 10 V DC power supply from a fan with a poten-
tiometer (PU/A). For this see the technical data of the control inputs and the wiring diagram SS-1035.
If the power of the EC-supply is not sufficient a customer-supplied sufficient external 10 V DC can be used (gal-
vanically separated from the mains). Alternatively the Helios module "EUR EC" can be used for various control
duties. The control cable must have the same insulation level as the mains cable.
2�11 Condensation
In case of periodical use, moist and warm media and through temperature variations (intermittent service), condensate
is built up in the duct and its draining off must be ensured. In case of condensation in ducting and casing of the fan,
appropriate measures must be taken (water bag, drainage) during installation. Under no circumstances must the motor
be exposed to water.

The units are supplied with a potentiometer in a polybag for setting the control voltage as standard. This allows any fan
speed to be set between min. and max. speed. If required, it must be installed in the terminal box (see wiring diagram
„6.3.1 Standard wiring diagrams with PU/A 10" auf Seite 11).
