3.8.3. Communication connector
Two Sub-D9 female connectors are used for CAN Open communication bus: one or the other
connector could be used (both connectors are pin to pin connected).
We recommend using a cable less than 3 meters length for CAN communication with BMM
(cable shielded with 120Ω adaptation).
These connectors are insulated from High voltage by a protective separation.
Figure 10: CAN connector
Nota: Spare_1 and Spare_2 pins are used for power supply gateway. The maximum current
must be 1A.
3.8.4. Power supply connector
A three contacts male connector (ref. 1440070 from Phoenix Contact) is used to supply the
BMM. See §2.1 for BMM power supply characteristics.
Compatible with ref. 1681172 or 1506888 from Phoenix Contact.
This connector is insulated from High voltage by a protective separation.
Figure 11: Power Supply connector
The 24V external power supply must be protected against overcurrent higher than 2A.
3.8.5. Earth connection
The 24V power supply of the BMM circuit must be earthed.
