7.4.1 Remote Port PIN Configurations

Description I/O

Power fail. Generates a high to low signal when the line fails.

Notes: Normally open status; closed when active. Open collector output must

be pulled up to a common referenced supply no greater than +40 V dc. The

transistors are capable of a maximum non-inductive dc load of 25 mA. Use

only pin 4 as the common.

Output

Reference ground for PINs 2 & 5 N/A

Battery low. Generates a high to low signal when the internal battery of the

UPS has less than 5 minutes of backup time remaining.

Notes: Normally open status; closed when active. Open collector output must

be pulled up to a common referenced supply no greater than +40 V dc. The

transistors are capable of a maximum non-inductive dc load of 25 mA. Use

only pin 4 as the common.

Output

Remote shutdown of the UPS

Notes: PIN 6 has a multi-purpose functionality: (1) Will shut down the UPS

when a high RS-232 level is sustained on PIN 6 for 0.36 seconds; (2) Is the

RS-232 data input (R x D). Keep this pin at high voltage (+5 V to +12 V) for

500 ms to shutdown the UPS. Activates when in the battery mode only.

Input

Reference ground for PIN 6 N/A

RS-232 data output Output

Note: PINS 2 and 5 rating: +40 V dc, 25 mA non-inductive

8.0 Maintenance & Storage

8.1 Maintenance

• Keep the unit clean (wipe with a soft, damp cloth) and vacuum the ventilation

intake periodically.

• Check for loose and bad connections monthly.

8.2 Storage Conditions

• Before storing, charge the UPS’s batteries for at least 4 hours.

• Store the UPS covered and upright in a cool, dry location, with the batteries fully

charged.

• To avoid unnecessary draining of the batteries, remove any accessories in the

accessory slot and disconnect any cables connected to the REMOTE PORT.

• During extended storage in environments where the ambient temperature is

-15°C to +30°C (+5°F to +86°F), charge the UPS’s batteries every 6 months;

+30°C to +45°C (+86°F to +113°F), charge the UPS’s batteries every 3 months.
