BLOW THE INSIDE OF THE EQUIPMENT WITH COMPRESSED AIR.
The insulation-measuring device will have 500 V D.C. and will be applied to the following points of the circuit:
- Supply-Earth: Ra > 50 Mohms.
- Welding-Earth: Ra > 50 Mohms.
- Supply-Welding: Ra > 50 Mohms.
BEFORE TURNING THE EQUIPMENT ON, ENSURE THAT IT IS OFF LOAD.
DO NOT OPERATE THE ON/OFF SWITCH WITH AN ELECTRICAL LOAD
