In order to make the connection correctly, it is necessary to comply with the following recommendations:
- Use a BELDEN 3105A cable.
- It is recommended to maintain a distance of approx. 100 m between the charging station and the external energy
meter. It is however possible to exceed this limit in relation to the type of system and being careful to respect the
intrinsic limitations of the RS485 connection.
- It is necessary to guarantee the absence of disturbances to guarantee correct communication.
- It is also necessary to insert the termination resistance of 120 Ohm on the serial line in order to minimise the
reflections, which is important for high bitrates and long cable distances
7.2.5. CLEAN CONTACT CONNECTION
The station has a clean contact to remotely control some actions.
To ensure that is operates correctly, the following must be observed
- Short circuit current: 10mA
- Cable section: 1mm2
- Max. distance: 50mt
COLLEGAMENTO
UTENTE
