Page 2: Module Description
Module description • BCC is an expanding, independent communication unit designed exclusively for the GWL CPM, which expands the protection options and enables remote management of batteries protected by the CPM. • It contains a 10 Mbps LAN interface for remote reading and writing of parameters to the CPM and two programmable potential-free switching NO/NC relays max 30V / 1A AC/DC. - Page 3 UTP cable to the minus (-) pole and the brown and white-brown wires to the plus (+) pole: RJ-45 Pin number Designation Color Tx + Tx - Rx + PoE - PoE- Rx - PoE + PoE + www.gwl.eu...

(I2C bus). All 4 COM.i2c terminals on the CPM are equipped with an optocoupler with galvanic isolati on from the BCC, so there is no risk of potenti al diff erence damage if the BCC unit is powered, for example, by a switching power supply from a source other than the CPM. www.gwl.eu... - Page 5 IP address of the BCC module into the compatible web browser (Microsoft Edge, Chrome, FireFox) – default address is http://192.168.0.100.
