1.5.5 High Voltage Safety
This power supply operates at a high enough voltage and possesses sufficient stored
energy to be capable of killing a person!
DO NOT TAKE SAFETY FOR GRANTED!
Pay strict attention to safety information and warnings in this manual.
This power supply produces extremely high voltages. DO NOT attempt to adjust any
load connection with High Voltage on. DO NOT attempt to open the power supply
enclosure unless the manual has been thoroughly reviewed and the internal layout is
understood. Never reach into the enclosure unless the power has been disconnected,
lock outs/tag outs applied, and the output is fully discharged. Be certain safety ground
connections are in place and secured.
DO NOT rely on the power supply’s instrumentation or controls to determine that the
output is safely discharged. The sensors and indicator LEDs are driven by amplifiers,
which are powered by an internal low voltage power supply. There may be dangerous
voltages present on the output, even if the unit appears “OFF”.
Assuming that High Voltage is always ON is the best way to avoid hazard to personnel.
Always shut off the supply circuit breaker(s) and follow an appropriate grounding
procedure to discharge the output before touching any exposed connections.
The High Voltage output is automatically discharged internally when HV is turned off.
Although redundancy is designed into the discharge circuit, in the unlikely event of
component failure the output may remain charged long after power is disconnected if it
is not manually discharged!
DO NOT allow anyone who has not reviewed this manual to perform any part of the
installation process or attempt servicing of the power supply. Any questions must be
brought to the attention of Telemark's service personnel.
DO NOT obstruct the cooling inlets or outlets. Overheating can result, which may
damage the power supply.
