General

The ELQZ-4-613-0 changeover switch is intended for use

together with type BCRW or BCRWD BASIC Wing

direct-driven fans with a fan motor with integrated

frequency converter.

The unit has two potentiometers for manually setting the

fan speed. It can be used for two-speed control of one

fan, or for single-speed control of two fans.

The changeover switch is equipped with fasteners for

mounting it on a 35 mm DIN rail and is designed

for installation inside a cubicle or a similar enclosure.
