Smart-UPS On-Line SRT5K/6K Tower/Rack-Mount 3U/4U2

Deenergizing safety

The UPS contains internal batteries and may present a shock hazard even when disconnected from the branch circuit (mains).

Before installing or servicing the equipment verify the following:

• Mains circuit breaker is in the OFF position

• Internal UPS the batteries are removed

• XLBP battery modules are disconnected

Electrical safety

• For models with a hardwired input, the connection to the branch circuit (mains) must be performed by a qualified

electrician.

• 230 V models only: In order to maintain compliance with the EMC directive for products sold in Europe, output cords

attached to the UPS must not exceed 10 meters in length.

• The protective earth conductor for the UPS carries the leakage current from the load devices (computer equipment).

An insulated ground conductor is to be installed as part of the branch circuit that supplies the UPS. The conductor

must have the same size and insulation material as the grounded and ungrounded branch circuit supply conductors.

The conductor will typically be green and with or without a yellow stripe.

• The UPS input ground conductor must be properly bonded to protective earth at the service panel.

If the UPS input power is supplied by a separately derived system, the ground conductor must be properly

bonded at the supply transformer or motor generator set.

Battery safety

• Before installing or replacing the batteries, remove jewelry such as wristwatches and rings.

High short circuit current through conductive materials could cause severe burns.

• Do not dispose of batteries by burning them. The batteries may explode.

• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes, and may be toxic.

Hardwire safety

• Verify that all branch circuit (mains) and low voltage (control) circuits are deenergized, and locked out before

installing cables or making connections, whether in the junction box or to the UPS.

• Wiring by a qualified electrician is required.

• Check national and local codes before wiring.

• Strain relief is required for all hardwiring (not supplied).

• All openings that allow access to UPS hardwire terminals must be covered. Failure to do so may result in personal

injury or equipment damage.

• Select wire size and connectors according to national and local codes.

General information

• The UPS will recognize as many as 10 external battery packs connected to the UPS. However there is no limit to the

number of XLBPs that can be used with the UPS.

Note: For each XLBP added, increased recharge time will be required.

• The model and serial numbers are located on a small, rear panel label. For some models, an additional label is located

on the chassis under the front bezel.

• Always recycle used batteries.

• Recycle the package materials or save them for reuse.
