Chapter 3 - Insatallation Procedure
Introduction
3.1.1
Equipment positioning and environmental considerations
The UPS cabinets are fitted with castors on the base to allow ease of movement and positioning. When
the equipment has been finally positioned ensure the adjustable feet are set so that the UPS will remain
stationary and stable (see figure 3-2).
The UPS can be lifted using either a fork lift, or a cradle. Take care when using either method not to
damage the UPS castors or jacking feet located on the bottom of the unit.
Ensure that the UPS weight is within the designated S.W.L. of any handling equipment. See the UPS specification
for weight details.
Do not move battery cabinets 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. Where ventilation is poor and
ambient temperature is high, 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.
Cables
All control cables should be screened and run separate from the power cables, in metal conduits or
metal ducts which are electrically bonded to the metalwork of the cabinets to which they are connected.
Cooling air flow
All the models in the 7200 range are force-cooled with the aid of internal fans. Cooling air enters the
module through ventilation grills located at the bottom of the front doors and is exhausted through the
fan grills located on the rear panel; you must therefore allow for a minimum gap of 250 mm behind the
unit to allow adequate air flow (see figure 3-1).
Clearances
Clearance around the front of the equipment should be sufficient to enable free passage of personnel
with the doors fully opened.
3.1.2
Raised floor installation
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 accompanying the system identify the
location and equipment through which the cabinet can be secured to the floor.
3.1.3
Battery Location
Temperature is a major factor in determining the battery life and capacity. Battery manufacturers quote
figures for an operating temperature of 20°C. Operating above this temperature will reduce the battery
life, operation below this temperature will reduce the battery capacity. On a normal installation the
battery temperature is maintained between 15°C and 25°C. Batteries should be mounted in an
environment where the temperature is consistent and even over the whole battery. Keep batteries away
from main heat sources or main air inlets etc.
Pedestals are required for the battery cabinets when they are located on raised floors, in the same way
as for the UPS cabinets.
