Connecting the power supply

Information about further electrical connections to be made (e.g. crankcase
heater, drive motor starting equipment, thermal protection of drive motor,
automatic start/ stop and other external electrical devices) can be found in the
plant manual (not supplied by Grasso).
1.3.8

Earthing connections

Grasso compressors and packages are equipped with litz-wires and earth
connecting points.
To avoid leakage current flowing through the components, disconnect all litz-
wires when arc-welding. After all installation functions are completed, reconnect
the litz-wires and ground the package to earth.
