VOLTAGE CONTROL RELAY

Read all the instructions carefully

Voltage control relay is an electronic control device to be mounted on a panel in a VCR

standard enclosure. It operates an external circuit following the tripping setting 2-DIN size

(direct or alternate voltage): threshold values, hysteresis and change-over delay can be

adjusted.

SAFETY INSTRUCTIONS

During the installation and operation of the device observe the following instructions:

1) The device must be installed by a qualiﬁed person, strictly following the wiring

diagrams.

2) The device must be installed in an electrical panel which, after installation, leaves

terminals inaccessible.

3) Do not power or connect the device if any part of it is damaged.

4) The electrical system in the building where the device is installed must feature a

circuit breaker and an overcurrent protection device.

5) The device is aimed for use in places with over-voltage category III and pollution

degree, 2 as per standards EN 61010-1.
