Series 7400 Single Phase 1+N UPS
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
Ø Ensure that the UPS weight is within the designated
S.W.L. of any handling equipment. See the UPS
specification for weight details.
Ø Do 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.
o 25kVA-40kVA 1 PH Models - 100mm required if the UPS is
situated on a solid floor. No space required if situated on a
raised floor.
o 50kVA-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.
