6 Service Information
This section provides specific information on servicing procedures for the T800-23-0011.
6.1 Warnings
6.1.1 Warning: Lethal Voltages
The T800-23-0011 power supply contains voltages that may be lethal.
Disconnect the mains IEC connector and wait for 5 minutes for the internal voltages to
drain away before dismantling.
Servicing should be carried out only by qualified technicians and should be attempted
only when powered through a mains isolating transformer of sufficient rating. It is
strongly recommended that the mains supply to the whole of the repair and test area is
supplied via an
earth leakage circuit breaker.
6.1.2 Warning: Fuse
The cable connecting the T800-23-0011 DC power output to the backplane also includes
a fuse. This fuse is critical to the IEC 60950 safety compliance of the T800 SL2 Base Sta-
tion and must be replaced with the same component or compliance will be voided.
The Fuse is a Bussmann TDC10 Series fast blow fuse rated at 12A (60V
AC
)
6.1.3 Caution: Handle With Care
Although this is a lightweight unit, it contains a number of quite heavy and fragile indi-
vidual components which are mounted directly on the PCB. Severe mechanical shock
may damage the PCB (e.g. solder joints, copper tracks) and/or components (e.g. fragile
ferrite magnetic materials).
