Parker AC30 - Earthing;Safety Details; Cooling Fans

F-3 Technical Specifications
AC30 series Variable Speed Drive
Safety
Overvoltage Category
Overvoltage Category III (numeral defining an impulse withstand level)
Pollution Degree
Pollution Degree II (non-conductive pollution, except for temporary condensation) for control electronics
Pollution Degree III (dirty air rating) for through-panel mounted parts
North America/Canada
Complies with the requirements of UL508C as an open-type drive.
EARTHING/SAFETY DETAILS
Earthing
Permanent earthing is mandatory on all units.
 Use a copper protective earth conductor 10mm² minimum cross-section, or install a second conductor in parallel with the
protective conductor to a separate protective earth terminal
 The conductor itself must meet local requirements for a protective earth conductor
Input Supply Details
(TN) and (IT)
Drives without filters are suitable for earth referenced (TN) or non-earth referenced (IT) supplies.
The drive is only suitable for earth referenced supplies (TN) when fitted with an internal filter. External filters are available for use
on TN and IT (non-earth referenced) supplies.
Prospective Short Circuit
Current (PSCC)
Refer to the appropriate Electrical Ratings table.
Earth Leakage Current
>10mA (all models)
COOLING FANS
The forced-vent cooling of the drive is achieved by 1, 2 or in some cases 3 fans. The Fan Rating gives the volume of air venting from the drive per fan.
