1. General Warnings
1. This equipment has been designed to be used only in restricted access areas.
2. This equipment must only be serviced by authorised and qualified service personnel.
3. Operators should not attempt to repair faulty units. There are no operator serviceable
parts inside. All fuses are only replaced
as part of a repair procedure in a repair
facility
by authorised personnel
and not as a maintenance procedure on site.
4. The powershelf magazine should be mounted in a rack that satisfies the requirements
for electrical enclosures and fire enclosures according to IEC60950 or equivalent
standard. For open rack use, the back of the magazine must be fully enclosed by its
covers and the AC wiring terminations must be protected by either an earthed casing or
an enclosure that provides double insulation.
5. The powershelves must be used with sufficient ventilation. After mounting, the air flow
paths into and out of the rectifiers must be unrestricted. Allow adequate flow for
exhaust air out of the rack.
6. Rectifiers are live at all times when the rectifier is plugged into the backplane connector.
The input AC disconnection device is the rectifier backplane connector.
7. When removing modules, especially if the ambient temperature is high and the unit has
been operating at maximum load, avoid skin contact with the metal casing as it may be
too hot to touch. Pull the unit halfway out of the magazine and let cool for 2-3 minutes
before handling.
