APC SUA500PDR User Manual

Mount the UPS on DIN Rail

This unit is designed to mount on a heavy duty DIN rail or on the back panel of an enclosure. For details on

DIN rail installation refer to the DIN rail installation guide included in the DIN rail package. The DIN rail kit is

not included.

When mounting on the back panel of an enclosure, select screws that are appropriate for the weight of this unit

and the mounting surface material.

Six screws must be used when mounting this unit in an enclosure. Three screws in the top of the bracket and

three screws in the bottom of the bracket. Failure to follow these instructions may result in damage to the unit.

Battery Installation

The UPS battery is shipped in a separate carton.

Refer to the installation guide included with the replacement battery for installation instructions.

Front Panel

Connect Power and Equipment to the UPS

Hardwiring should be performed by a qualified electrician. Use appropriate size wires.

1. The UPS features a transient voltage surge-suppression (TVSS) screw located on the front panel. The

TVSS screw is used for connecting the ground lead on surge suppression devices such as telephone and

network line protectors.

Prior to connecting the grounding cable, ensure that the UPS is NOT connected to utility or battery

power.

2. Hardwire the UPS.

– In 230 V applications the UPS must be protected with a circuit breaker that complies with

European standards for branch rated protection per the country of installation.

– In 208 V applications, the SUA500PDRI must be protected by a dual pole, 10 A branch rated

circuit breaker with UL489 rating.

– The 120 V SUA500PDR has supplementary circuit breaker protection. The unit should be

protected by a single pole, 15 A branch rated circuit breaker with a UL489 rating. Ensure that

the branch circuit breaker is off prior to wiring the unit.

3. Connect equipment to the UPS.

4. Add optional accessories to the SmartSlot located on the front panel.

5. Turn on all connected equipment. To use the UPS as a master on/off switch, be sure all connected

equipment is switched on.

6. Press the Test button on the front panel to start the UPS.

– The battery charges to 90% capacity during the first four hours of normal operation.

– Do not expect full battery run capability during this initial charge period.

7. For optimal computer system security, install PowerChute monitoring software included with the UPS.

Emergency Power Off

The emergency power off (EPO) feature is user configurable. EPO provides immediate de-energizing of

connected equipment from a remote location, without switching to battery operation.

Use a normally-open contact to connect the EPO COM terminal to the EPO terminal.

The EPO interface is a Safety Extra Low Voltage (SELV) circuit. Connect it only to other SELV

circuits. The EPO interface monitors circuits that have no determined voltage potential. Such closure

circuits may be provided by a switch or relay properly isolated from the utility. To avoid damage to the

UPS, do not connect the EPO interface to any circuit other than a closure type circuit.

Use one of the following cable types to connect the UPS to the EPO switch.

• CL2: Class 2 cable for general use.

• CL2P: Plenum cable for use in ducts, plenums, and other spaces used for environmental air.

• CL2R: Riser cable for use in a vertical run in a floor-to-floor shaft.

• CLEX: Limited use cable for use in dwellings and for use in raceways.

• For installation in Canada: Use only CSA certified, type ELC (extra-low voltage control cable).

• For installation in other countries: Use standard low-voltage cable in accordance with national and

local regulations.

Diagnostic Utility

Voltage

The UPS has a diagnostic feature that indicates the utility voltage.

The UPS starts a self-test as part of this procedure. The self-test does not

affect the voltage display.

Press and hold the Test button to view the utility voltage bar graph indicator.

After a few seconds, this five-LED Battery Charge indicator on the right of

the display panel will show the utility input voltage.

Refer to the figure on the left for the voltage reading (values are not listed on

the UPS).

The indicator on the UPS shows the voltage is between the displayed value

on the list and the next higher value (see Troubleshooting).
