Care, Inspection, Storage and Maintenance
MOBILE WORKSTATION WM-NP2

2.
Periodically check the electrical resistance of the conductive antistatic castors to assess
antistatic effectiveness.
Periodically clean each castor wheel to remove non-conductive material such as cleaning
wax and floor polish as these will impair the antistatic effectiveness of the castors.
3.
Regularly check the shelf and securing screws of any accessories that are fitted, particularly
monitor platforms. If necessary, retighten the screws using the tools provided.
4.
The separation transformer should undergo routine checks for electrical safety and correct
function annually or as dictated by local policy. Typical checks would include inspection of the
power supply and equipment cables for damage and for full engagement with their
respective connectors, and tests for earth continuity and insulation resistance. Also check
(listen) for correct operation of the inrush limiting circuit (see Chapter 9) when power is
applied.
5.
The power supply cable to the transformer is vulnerable to damage from the castors and
should be checked regularly. It can be replaced by removing four screws from the securing
clamps below the workstation back frame and disconnecting it from the transformer.
Replacement is the reverse of removal, but ensure that the cable is firmly inserted into the
transformer connector before securing. Refer to Chapter 8 Spare parts for the part number of
the replacement power cable.
6.
If it becomes necessary to remove the separation transformer from the mobile workstation
for testing, disconnect all cables from the transformer then place supports between the
transformer and the floor at the front and rear. Remove five M8 nuts using a 13mm A/F
socket, then carefully remove the supports and lower the transformer to the floor.
CAUTION
• The transformer weighs approximately 30kg, and care should therefore
be exercised during handling. When lifting the transformer, it is
recommended that the assistance of a second person is sought.
• Removal of the transformer should only be undertaken by suitably
qualified personnel.
• Removal of the transformer will result in the workstation being
potentially less stable. Extra care should be taken to ensure that the
workstation is standing on a level surface, particularly if it is loaded with
equipment.
7.
Electrical safety checks should only be performed by suitably qualified personnel.The
expected service life of the workstation and transformer is 5 years.
8.
The above maintenance checks should be performed to ensure the workstation remains in a
good, safe working condition. Failure to perform these checks could lead to a potentially
unsafe workstation.
