2.1 Personal Safety
2.1.1 Unpacking and Moving the Equipment
To prevent personal injury and equipment damage, we recommend that two
people unpack and move the equipment.
Caution
A subrack complete with modules can weigh up to 62lb
(28kg), or up to 66lb (30kg) complete with packaging. We recommend
that you have another person help you unpack and move the equipment.
The TBAA03-16 carrying handles will make it easier to move the
equipment once it has been unpacked. If necessary, remove the modules
from the subrack before moving it (refer to
“Replacing Modules” on
page 103 ). In all cases follow safe lifting practices.
2.1.2 Lethal Voltages
Warning
The PMU contains voltages that may be lethal. Refer
to the ratings label on the rear of the module.
The equipment must be installed so that the rear of the PMU is located in a
service access area which is accessible only by qualified personnel. The
PMU must be connected to the mains supply source by qualified personnel
in accordance with local and national regulations.
Disconnect the mains IEC connector and wait for five minutes for the
internal voltages to self-discharge before dismantling. The AC power
on/off switch does not isolate the PMU from the mains. It breaks only
the phase circuit, not the neutral.
The PMU should be serviced only by qualified technicians. There are no
user-replaceable parts inside. If the PMU is damaged and does not function
properly, stop the module safely and contact your regional Tait office
immediately.
All servicing should be carried out only when the PMU is powered through
a mains isolating transformer of sufficient rating.
