1.3 Safety
Power to the PGGE unit is to be supplied by an external DC voltage power supply
that must be ground isolated so that the DC voltage output floats with respect to
ground. For any power supply used, the maximum specified operating parameters
for the units are:
Maximum Limits
250VDC
30watts power
125mA current
55ºC ambient temperature
Current to the unit, provided from the external power supply, must enter the unit
through the lid assembly, providing a safety interlock to the user. Current to the unit
is broken when the lid is removed.
Do not attempt to use the unit without the
safety lid, and always turn the power supply off before removing the lid, or when
working with the unit in any way. Follow safety precautions specified by the
power supply manufacuturer.
