Note: If there is no evident need for global type functions in the PRxx2 based system, it is
recommended not to install CPR32-SE.
Installation
The CPR32-SE module can be installed in any metal or plastic enclosure which guarantees adequate
protection from dust, water and moisture. Also, enclosure should assure required temperature,
ingress protection and security. All wirings must be made before module will be powered on.
Note: CPR32-SE will not start operation from battery itself. It is necessary to provide AC supply to
start module’s operation.
All devices working in access network and connected to the same RS485 communication bus should
share common minus (common ground). In order to assure this condition use separate wire (it can
be a signal type one) and connect all minuses of all powers sources in the system. If required
system supply minus can be earthed in one, arbitrary selected point.
Note: It is forbidden to short positive (+) supply outputs from various devices working in the
system.
