-48VDC Powering

1. To power the 1595R appliance with -48VDC supply, you need a special power source/supply, such as

Delta DPS1800-48/30.

2. Connect the power supply "+" pole to the 1595R "+" pole.

3. Connect the power supply "-" pole to the 1595R "-" pole.

Power sub-station

To comply with the power sub-station certification (IEEE 1613 and IEC 61850-3), you must connect both

power inputs for power redundancy.

To connect DC power to the equipment:

1. Turn OFF all power sources and equipment that will be attached to this appliance.

2. Connect protective earthing first, with at least 14 AWG G/Y color PE conductor, diameter 4.0mm min.,

screw type PE terminal, and a Spring/Star washer to provide satisfactory locking.

3. Attach signal cables to the appliance.

4. Attach the power cords to the appliance.

For DC systems, make sure the polarity is 12-60VDC, or -48VDC connections.

5. Attach the signal cables to other devices.

6. Connect the power cords to their sources.

7. Turn ON all the power sources.

To disconnect DC power from the equipment:

1. Turn OFF all power sources and equipment that are attached to this appliance.

Disconnect DC power sources at the breaker panel or by turning off the power source. Then remove

the DC cables.

2. Remove the signal cables from the connectors.

3. Remove the protective earthing conductor from the devices.

Tolerance

This equipment is intended for power supplied by DC mains.

The product supports 10.2VDC~72VDC, but with no power input tolerance.

Make sure the product is connected with a power supply of output voltage lower than 72VDC. A UPS,

battery or power regulator is recommended.

If the power supply cannot provide stable voltage, we recommend to select lower voltage like 48VDC

to prevent damage due to over voltage.
