5.4.Replacing the Batteries

(QUALIFIED SERVICE PERSONNEL ONLY)

The CPE On-Line Series UPS has an easy to replace batteries. Please read all of the WARNINGS and CAUTIONS before attempting to service the batteries.

•WARNING – This Uninterruptible Power Supply contains potentially hazardous voltages. Do not attempt to disassemble the UPS beyond the battery replacement procedure. This UPS contains no user serviceable parts. The repairs and the Battery replacement must be performed by

QUALIFIED SERVICE PERSONNEL ONLY.

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

•CAUTION – Do not dispose of batteries in a fire. The batteries may explode. The batteries in this UPS are recyclable. Dispose of the batteries properly. The batteries contain lead and pose a hazard to the environment and human health if not disposed of properly. Refer to local codes for proper disposal requirements or return the battery to MINUTEMAN.

•CAUTION – Although battery system voltages are 36VDC, 72VDC and 96VDC the battery system can still present a risk of electrical shock. These batteries produce sufficient current to burn wire or tools very rapidly, producing molten metal. Observe these precautions when replacing the batteries:

1.Remove watches, rings, or other metal objects.

2.Use hand tools with insulated handles.

3.Wear protective eye gear (goggles).

4.Wear rubber gloves and boots.

5.Do not lay tools or other metal parts on top of batteries.

6.Disconnect the charging source prior to connecting or disconnecting the battery terminals.

7.Determine if the battery is inadvertently grounded. If the battery is, remove the source of the grounding. Contact with any part of a grounded battery can result in an electrical shock. The likelihood of such shock will be reduced, if such grounds are removed during installation and maintenance.
