Chapter 1 - Installation Procedure Liebert Hipulse E Installation Manual
Installation (Mechanical) Single or '1+N' UPS System
Page 1-4 (07/04)
1.3.8 Clearances
Liebert Hipulse E has no ventilation grills at either side or at the rear of the UPS. To enable routine tightening of power
terminations within the UPS, it is recommended that service access of 800 mm (minimum) be allowed for at the rear.
Clearance around the front of the equipment should be sufficient to enable free passage of personnel with the doors
fully opened. It is important to leave a distance of 800 mm between the top of the UPS and the ceiling of the room in
which it is installed to permit adequate circulation of air coming out of the unit.
1.3.9 Floor installation
The installation diagrams in Chapter 6 of this manual identify the location of the holes in the base plate through which
the equipment can be bolted to the floor. 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. Refer to the base view to design this pedestal.
1.3.10 Fixing of the magnetic components
Before the equipment is in place, remove the transportation restraints that hold the input inductance and output
transformer in place.
1.3.11 Cable entry
Cables can enter the UPS cabinet from bottom.
Note
When selecting the power cables for side entry to a module located on a solid floor, consideration
must be given to the minimum permissible radius of the proposed cables to ensure that they can be
fashioned to reach the UPS connection busbars.
1.3.12 Top Cable entry
Optionally a top cable entry extension may be used, see the figures in Chapter 6.
The cabinet extends the overall width of the UPS and permits connection of all incoming AC/DC power cables from above
through horizontally supported copper bars.
The top cable entry option is fitted on the side of the UPS cabinet and is supplied without side panels; the side cover
from the UPS being used.
The cabinet with cables coming in from the top for the 300 kVA UPS must be positioned on the right side, whereas
the cabinet for the 400 kVA UPS must be positioned on the left side.
This facilitates cable entry through the top aluminium panel after the appropriate cable entry holes have been cut. Roof-
mounted eyebolts are fitted on shipment to optional cabinet, to enable the cabinet to be crane-handled. These can be
removed once the equipment has been finally positioned.
Note 1: The top cable entry also includes the power connection cables between the cabinet and the UPS.
Note 2: For special installation requirements regarding the position of the optional unit for incoming cables entering
from the top, special alternatives to the standard position are available.
1.4 Preliminary Checks
Before you install the UPS hardware you should carry out the following preliminary checks:
1. Verify that the UPS room satisfies the environmental conditions stipulated in the equipment specification,
paying particular attention to the ambient temperature and air exchange system.
2. Remove any packaging debris, then visually examine the UPS and battery equipment for transit damage, both
internally and externally. Report any such damage to the shipper immediately.
1.4.1 Identification
The equipment supplied has an identification tag on the back of the main door reporting:
the type, size, and main calibration parameters of the UPS. A metal disk fastened to the inside top of the cabinet is
engraved with its serial number.
Record the model and serial numbers in the table at the beginning of this installation manual. A record of this
information is necessary should servicing be required.
