Back-UPS ES 400/550/700

Stage 1: Connect Battery

For safety, the Back-UPS ES is shipped with one battery wire disconnected. The Back-UPS ES will not operate until the wire is connected to the touch.

NOTE: Small sparks may occur during battery connection but this is normal.

Battery stages

  1. TURN the Back-UPS ES over and slide the battery compartment cover off of the battery housing.
  2. LIFT the battery out of the compartment and connect the black wire to the negative (-) battery terminal. Ensure the batteries are installed as shown above.
  3. SLIDE the battery compartment cover back onto the battery housing.

Stage 2: Connect Equipment

Back up surge protection

These outlets are powered whenever the Back-UPS ES is switched ON. During a power outage or other AC problems (brownouts, over-voltages), these outlets will be powered for a limited time by the Back-UPS ES. Plug your computer, monitor, and two other data-sensitive devices (external disk or tape drive) into these outlets.

Surge Protection Only

The outlets provide full-time protection from surges even if the Back-UPS ES is switched OFF. Plug your printer, fax machine, scanner, or other peripherals that do not need battery power into these outlets.

Place the Back-UPS ES to avoid:

  • Direct sunlight
  • Excessive heat
  • Excessive humidity or contact with fluids

Plug the Back-UPS ES power cord directly into a wall outlet; not a surge protector or power strip. The wall outlet should be located near the equipment and be easily accessible.

Connect Modem / Phone / DSL / Fax / 10/100 Base- T/HPNA to Surge Protection.

The Back-UPS protects a single line (2-wire) phone (including Digital Subscriber line – DSL), Home Phoneline Networking Association (HPNA) type equipment, modem, 10/100 Base-T Ethernet, or fax machines from surges when connected through the UPS as shown in the drawing below.

Note: Telephone Cable OR Network Cable should be connected to Surge Protection ports. Do not connect the UPS surge protection ports to both Telephone and Network System cables at the same time.

Connect Computer Cable (This is applicable for 550/700 only)

The supplied cable and software provide automatic file saving and shutdown of the operating system in the case of a sustained power outage.

Connect the cable to the Data Port of the Back-UPS ES. Connect the other end of the cable to the USB port on your computer. The software will automatically find the USB Port of your computer

Stage 3: Power On and Install Software

Press the ON/OFF switch to power the unit ON.

A single short beep and the green “Power On” indicator confirms that Back-UPS ES is on and ready to provide protection. The Back-UPS ES should charge for at least 16 hours to ensure sufficient run-time. The unit is being charged whenever it is connected to AC power, whether the unit is turned ON or OFF. Install the PowerChute™ Personal Edition software (This is applicable for 550/700 only).
Place the PowerChute Personal Edition CDROM into your computer and follow the installation instructions on the screen.

Wall Mount of UPS

The UPS can be mounted vertically or horizontally to a wall surface. Use the template below to position the mounting fasteners (not supplied). Wall mount the UPS as follows;

1. Hold this page against the wall in the desired mounting location.

2. Use thumbtacks or tape to hold this page in place against the wall. Use a sharp nail or pin to puncture the centre of each template circle to mark the wall.

3. Install the mounting fasteners at the marked locations. Leave the head of both fasteners 8mm (5/16) out from the face of the wall. The fasteners must be able to support 6.8 Kg.

4. Mount the UPS by positioning the key-hole slots over the heads of the mounting fasteners. For vertical mounting, slide the UPS down into place. For horizontal mounting, turn it slightly counter clockwise until it is securely in place.
