Series 7400 Single Phase 1+N UPS

3.1.1Equipment positioning and environmental considerations

3.1.2Raised Floor Installation

The UPS cabinets can be moved by fork lift or crane. Fork lift apertures are provided in the sides of the base plate and are accessible after removing blanking covers fitted to the side panel ventilation grills. Roof - mounted eye- bolts are fitted to enable the cabinet to be crane-handled. These can be removed once the equipment has been finally positioned.

WARNING

ØEnsure that the UPS weight is within the designated S.W.L. of any handling equipment. See the UPS specification for weight details.

ØDo not move the battery cabinet with the batteries fitted.

The UPS module should be located in a cool, dry, clean-air environment with adequate ventilation to keep the ambient temperature within the specified operating range. If necessary, a system of extractor fans should be installed to aid cooling-air flow, and a suitable air filtration system used where the UPS is to operate in a dirty environment.

Cooling air flow

All the models in the 7400 range are forced-cooled with the aid of internal fans. Cooling air enters the module through ventilation grills located at the bottom of the front, back and side panels (and the door in the case of the 50, 60, 80, 105 & 120 kVA models) and exhausted through grills located in the equipment roof. When the equipment is located on a raised floor, and bottom cable entry is used, additional cooling air also enters the UPS via the floor void.

Clearances

To allow adequate cooling air flow, you should position the equipment with the following space around the back and sides.

o25kVA-40kVA 1 PH Models - 100mm required if the UPS is situated on a solid floor. No space required if situated on a

raised floor.

o50kVA-125kVA 1 PH Models - 100mm required in all cases.

The UPS modules do not require back-access for maintenance servicing; but, where space permits, a clearance of approximately 4 feet (1.2 meters) will ease access to some component parts. Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the door fully opened.

If the equipment is to be located on a raised floor it should be mounted on a pedestal suitably designed to accept the equipment point loading. The installation diagrams in the back of this manual identifies the location of the holes in the base plate through which the equipment can be bolted to the floor.
