6 Service Information
This section provides specific information on servicing procedures for the T809-10.
6.1 Warnings
Please observe the following warnings and cautions.
6.1.1 Warning: Lethal Voltages
The T809-10 power supply contains voltages that may be lethal.
Before dismantling, disconnect the mains IEC connector and wait 5 minutes to allow the
internal voltages to drain away.
Servicing should only be carried out 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 Caution: Handle With Care
Although this is a lightweight unit, it contains a number of quite heavy and fragile indi-
vidual components that are mounted directly onto the module’s printed circuit board
(PCB). Severe mechanical shock may damage the PCB (for example, solder joints and
copper tracks) and/or components (for example, fragile ferrite magnetic materials).
6.1.3 Warning: Safety Approval
Safety Approval will become void if T809-10 components are replaced with non-equiva-
lent rated or non-certified/non-approved components. Contact Tait Electronics Support
before replacing components of the T809-10.
The power supply module inside the T809-10 is not a user serviceable item. This module
contains components that operate at voltages that may be lethal. Do not open this
module.
