This chapter describes the configuration and installation of the HEBC+ power supply. Figure 2 shows
the HEBC+ connectors.
Figure 2
2.2 Main Input Power Connector
Input power is connected to the HEBC+ by a Molex plug and pin connector CN2. The power supply
accepts DC input voltages in the range of 10VDC to 40VDC. Unregulated vehicle power is connected
as follows:
- Terminal 1:Common (0VDC)
- Terminal 2: Hot ”polarity”
2.3 Battery Connector
Batteries are connected to the HEBC+ by a Molex plug connector, CN1. The HEBC+ accepts DC
battery voltages in the range 10V to 35VDC through the Battery Power Connector.
