American Power Conversion CP150E48 Output Connections, Pin Communication Signals Connector

Output Connections

7-Pin Communication Signals Connector

Connect equipment to the UPS output connector receptacle via the seven-pin output connector (included), or use an APC custom data cable, (must be ordered separately).

The PowerShield communication signals are isolated from its internal circuitry via open collector opto-coupled transistors. The connection labeled “Signal Return” is a common return point for all communication signals. In the typical application, the attached equipment digital ground connects to Signal Return, and pull-up resistors turn the open collector signals into logic levels.

Voltage output

Signal return.

Low when operating from utility line. Open when operating from battery.

Low when battery is charged. Open when battery fails the Self Test. Low when battery is present. Open when battery is missing.

Low when battery is near full charge capacity. Open when operating from a battery with < 20% capacity.

16-Pin Terminal Board CPW029 Option

The terminal board supplies uninterruptible power for up to eight sites grouped around the power supply.

The terminal board output fuses automatically reset.

Connect the positive W2 and negative W1 wires to the number one and two pins respectively on the 7-pin communication signal connector. See diagram.

Output Grounding

Either polarity of the output can be grounded to the ground stud located on the right side of the display panel. See diagram. Apply a non-oxidant paste to the ground stud prior to connecting the ground wire.
