Emerson 610 Manuel D’Utilisation

Optional battery cabinets are available from Liebert and other qualified vendors. Consult your sub-

mittal package for details.
Several models of optional battery cabinets with varying run times are available. Each model is 78" 

(1981mm) high and has forklift slots. Refer to Figures 44 through 46. The battery cabinet cells range 

from 90 to 150 ampere-hours. The same model battery cabinet may be paralleled in multiple cabinet 

strings for additional capacity. Battery capacity (in minutes) at your installation will depend on cabi-

net model, number of cabinets and amount of critical load on the UPS.
1. Handling. The battery cabinet weighs from 3060 to 5300 lbs. (1388 to 2404kg). Forklift slots are 

provided for ease of handling.

2. Cabinet Inspection. Remove all panels and visually inspect the batteries, bus connections, and 

cabinet for any damage. If any foam blocks were placed between shelves to restrain movement 

during shipment, remove them now. Exercise caution—voltage is present within the 

battery cabinet even before installation. If there are signs of damage, do not proceed. Call 

Liebert Global Services at 1-800-LIEBERT.

3. Battery Storage. The batteries used in the battery cabinet retain their charge well. The 

batteries can be stored indoors in a temperature-controlled environment, for up to six months 

without any appreciable deterioration. Self-discharge rate of the batteries is approximately 3% 

per month when the batteries are stored in temperatures of 59°F to 77°F (15-25°C). If the battery 

cabinet must be stored for longer than six months, contact Liebert Global Services. The battery 

cabinet should never be stored outdoors or on a loading dock.

4. Installation. Battery cabinets can be located conveniently next to each UPS module. The front-

access-only-design eliminates side and rear service clearance requirements.

5. Reinstallation. If at any time it becomes necessary to move the battery cabinet to another 

location, contact Liebert Global Services to inspect the internal battery hold-down straps.

6. Environment. Locate the battery cabinet in a clean, dry environment. Recommended 

temperature range for optimum performance and lifetime is 68°F to 77°F (20-25°C).

7. Service Clearance. Allow front access to the battery cabinet at all times for maintenance and 

servicing. Electrical codes require that the battery cabinet be installed with no less than 3 ft. (1m) 

of clearance at the front of the cabinet when operating. Side and rear panels do not require service 

clearance.

8. Side Panels. To connect battery cabinets together, remove the protective side panels by 

removing the retaining screws that hold the side panels in place.

9. Cables. Multiple battery cabinets may be bolted together in a daisy-chain configuration. Cables 

for this setup may be run between paralleled battery cabinets through cutouts in the top of the 

cabinets, eliminating the need for external conduit runs. Route cables before moving 

cabinets into final position for bolting together. Low voltage control wiring must be kept 

separate from the power wiring. Remove top panels for access, if required. No top or bottom entry 

cables are required, except for remotely located cabinets, which require conduits. Refer to 

Figures 44 through 46 or your submittal drawings for instructions on wiring cabinets in parallel.

10. Grounding. The battery cabinets have ground studs near the busbar connections. Use an 

equipment grounding conductor to connect the lugs of the cabinets together and to connect the 

cabinets to the ground busbar in the UPS module.

NOTE
The 300-750kVA UPS module is approximately 2 to 6 in. (51-152 mm) deeper than the battery
