CURRENT CONTROL RELAY
Read all the instructions carefully
Current control relay CCR is an electronic control device to be mounted on a panel in a
standard 2-DIN size enclosure. It operates an external circuit following the set tripping
value (direct or alternate current): 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.
