5 DC Distribution

5.1 DC Cabling

You can find DC output which marked Load + and Load – behind the shelf of the left hand side.

5.2 Low Voltage Battery Disconnect (System equipped with PDU)

The low voltage disconnect contactor is installed in front of the battery connection bus. Battery and system bus are connected in parallel. When LVDS opens, it disconnects the batteries from the system bus.

5.3 Battery Connections (System equipped with PDU)

The battery connections which are behind the distribution module should be made through the breaker. BAT + for battery positive and BAT – for battery negative.

5.4 Battery Temperature Probe Connection (System equipped with PDU)

The battery temperature probe senses the battery temperature and sends the signal back to the ALU. The temperature is used to determine the temperature compensation voltage. A temperature sensor is included with each Power Shelf. To connect the temperature sensor, perform the following steps:

1.Connect the sensor to the connector labeled TB located behind the shelf.

2.Attach the copper lug sensor to the center position.
