WARNING
SHOCK HAZARD, LETHAL VOLTAGES
Many models generate voltages greater than 60 VDC, with some models
rated at 950 VDC! Ensure that all instrument connections, load wiring, and
load connections are either insulated or covered using the safety covers
provided, so that no accidental contact with lethal voltages can occur.
WARNING
SHOCK HAZARD
Never touch cables or connections immediately after turning off the unit.
Depending on the model, lethal voltages can remain at the output terminals
for several seconds after turn-off. Verify that there is no dangerous voltage
on the output or sense terminals before touching them.
WARNING
SHOCK HAZARD from external energy sources
Because the instrument can be used as a load to sink current, hazardous
voltages from an external energy source such as a battery may be present on
the output terminals even with the unit turned off. Provision must be made
to disconnect the external energy source before touching the output or
sense terminals.
WARNING
Do not operate in an explosive atmosphere
Do not operate the instrument in the presence of flammable gases or fumes.
WARNING
Do not remove the instrument cover
Only qualified, service-trained personnel who are aware of the hazards
involved should remove instrument covers. Always disconnect the power
cable and any external circuits before removing the instrument cover.
