2 General Safety and Regulatory
Information
This chapter provides general information on safety precautions for
operating the TB9100 base station.
2.1 General Safety
Personal Safety
Lethal Voltages
Warning!!
The PMU contains voltages that may be lethal.
Refer to the ratings label on the rear of the
module.
The TB9100 base station must be installed so that the rear of the PMU is
located in a service access area. The PMU must be connected to the mains
supply source by trained 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 nearest Tait Dealer or
Customer Service Organization immediately.
All servicing should be carried out only when the PMU is powered through
a mains isolating transformer of sufficient rating. We
strongly recommend
that the mains power to the whole of the repair and test area is supplied via
an earth leakage circuit breaker.
