This section contains procedures for testing the power system prior to applying
power to the cabinet.
31st Oct 01
WARNING
The power system checks provided in this section must be
performed before the equipment is powered up.
WARNING
Up to 415 V ac is present within the cabinet when the
cabinet is directly connected to an ac supply.
Earth straps are not to be worn during the commissioning
of the ac and dc power system. Watches and other
jewellery should be removed.
Only insulated tools should be used.
CAUTION
This equipment contains CMOS devices and is vulnerable
to static discharge. Although the damage may not be
immediately apparent, CMOS devices may be damaged in
the long term due to mishandling causing barrier
breakdown.
The approved earth strap (high impedance) must be worn
at all times when adjusting or handling the processor
cards (but see the warning above, regarding the use of
earth straps).
If the cabinet door is kept open for long periods of time
during commissioning, an alternative method of cooling
must be provided to avoid damage to the equipment
through overheating.
