Place The UPS Properly

It is necessary to select a proper environment to install the unit, in order to minimize the

possibility of damage to the UPS and extend the life of the UPS.

• Keep at least 20cm (8") clearance from the rear panel of the UPS from the wall or

other obstructions.

• Do not block the air-flow to the ventilation openings of the unit.

• Ensure that the installation site environmental conditions are in accordance with the

UPS working specifications to avoid overheat and excessive moisture.

• Do not place the UPS in a dusty or corrosive environment or near any flammable

objects.

• This UPS is not designed for outdoor use.

Setup

IMPORTANT: Plug the UPS onto the wall receptacle to charge the UPS for over 8 hours

after initial installation.

Initial Battery Charge (required before first use)

IMPORTANT: Plug the UPS onto the wall receptacle to charge the UPS for over 8 hours

after initial installation.

Plug-In Charge

If the Input Power Cord is connected to the wall receptacle properly and the utility is normal,

the UPS will start charging automatically without processing “Turn On” procedure.

Note: Charge the batteries for at least 8 hours every 3 months when the UPS is in an

idle condition.

Connect Utility and Load

First, connect the UPS with Utility, then plug the loads into the Outlets on the rear of the

UPS (FIG. 6). To use the UPS as a master “On/Off” switch, make sure that all of the loads

are switched “on”. These UPS outlets provide battery backup and surge protection to the

equipment when Utility voltage is out of window.

Caution: Do not connect a laser printer to the UPS outlets.

Connect Network Surge Protection

Connect a 10 base-T / 100 base-T network cable with the RJ-45 network surge protection

“IN” jack on the rear of the UPS. Connect from the “OUT” jack with network cabling to

network equipment (FIG. 7).

NOTE: If using the NXA-UPS1500 as part of a MAX system, do not run the A/V segment of

the network through the RJ45 network surge protection jack on the UPS.

The A/V segment of a MAX network requires a GB Ethernet switch, and the NXA-UPS1500

only provides a 10/100 connection.

You can connect the Control segment of the MAX network to the UPS, since it does not

require a GB connection to operate properly.

Connect the RS-232 Communication Port

Connect the supplied RS-232 interface cable between the RS-232 port on the rear of the

UPS and an available RS-232 port on the NetLinx Master (FIG. 8).

RS-232 Communication Port Pin Assignment

The NXA-UPS1500 provides a DB9F (9-pin female) connector to communicate via RS-232.

The pinout configuration for the RS-232 Communication Port connector is shown in FIG. 9:

Operation

Turn On the UPS

1. Connect the UPS to the wall receptacle. LCD will display “OFF”, when Utility is nor-

mal. If there is nothing on the LCD, go to step 3.

2. Push the “On” Switch on the front panel to start the UPS. Both the LCD and Utility

LED (Green) are lit. The start-up procedure is completed and the loads are supplied

by the UPS.

To cold start the UPS, press the “On” Switch on the front panel for approximately 3

seconds until the LCD lights up and buzzer sounds, then release the “On” Switch.

The UPS starts operating and Battery Backup LED (Amber) lights up. The cold start-

up procedure is completed and the loads are supplied by the UPS.

The UPS will run under Backup mode and the buzzer alarms every 2 seconds in

case of blackout or over/under voltage. On the contrary, If Utility is back to normal

and then the UPS will run under Utility mode and silence alarm.

CAUTION: The UPS will remain at “NO” output, if the start-up operation is not proceeded

properly even though the Input Power Cord is connected to the wall receptacle.

Turn Off the UPS

1. Press the “Off” Switch for at least 3 seconds to turn off the UPS.

In some occasions, the UPS will shut itself down in case of overload, output short-

circuited or battery cutoff point reached in the Backup mode.

2. The UPS will automatically shut off the output and beep for 5 seconds then

completely shut itself down.
