13.3 EDP70 PLUS above 20kVA: Battery Installation/Start-up
SAFETY
- Ensure the Equipment ON/OFF Switch is turned to OFF before starting to install the batteries. If the
Equipment ON/OFF Switch is not turned to OFF the equipment and battery may be damaged. It is
also essential for safety reasons that the battery connectors are disconnected before to remove
the fuse of the battery cubicle.
- Stand on a rubber mat and use insulated tools.
- Remove all personal effects, rings, watches, pens, which might cause a short circuit when
working on the battery. Batteries are live at all times and short circuits can melt metals and cause
injury, damage or fire.
- DO NOT smoke or use naked flames and avoid creating arcs or sparks when working on the
equipment; do not wear clothes which may generate static electricity.
- The sealed lead-acid batteries contain sulphuric acid. If a battery container is broken any acid
leaking will cause burns on contact with skin and attack metal, paint and fabrics. Any area
contaminated with acid should be thoroughly washed with large volumes of clean water. Rubber
gloves should be worn when handling damaged batteries.

PLUS UPS follow the following procedure:
1. Shutdown the UPS using the procedure set out in section 9. Access the terminal rail.
2. Be sure that all the batteries in the cubicle(s) are disconnected. Remove the fuses from the battery
cubicle(s).
4. Wire the cubicle according to the extension battery cubicle wiring instructions and the relevant
battery layout diagram.
5. Replace the fuses on all the cubicles then connect all the inter-shelf connectors, and replace all the
panels and restart UPS using the procedure described in section 7.
