Power Supply; Onboard Network Concept - Bosch C 60 Manual

2 Power supply

Please ensure that you have a good ground installation. That means:
A ground that has a solid, low resistance connection to the negative battery terminal.
·
Connection should be free from dirt, grease, paint, anodizing, etc.
·
Use large diameter wire
·
More metal-to-metal contact is better!
·
The following notations for power signals are used:
term15 is a switched battery rail controlled by the IGN-switch
·
term30 is an unswitched battery positive rail (same as battery positive terminal)
·
term31 is an unswitched ground rail (same as battery negative terminal)
·
Be careful to observe current limits of wires and connector pins!
