WARNING
Electrical-trade personnel must do electric installation on the Centac
compressor. Electricity can cause serious injury or even death if proper handling and
installation procedures are not observed. Contact a qualified electrical installation
contractor for help installing and/or maintaining any electrical services to this
compressor.
NOTE
Design and installation of disconnect, overvoltage, short circuit, and overload
protection is the responsibility of the customer.
Control Panel Power
The standard Centac compressor control circuitry is designed for a 120 VAC source. If the
customers source is greater than 120 VAC, a control transformer must be used. Check the
Electrical Schematic to determine whether the control transformer has been factory
installed.
To properly make electrical connections to the control panel, refer to the Electrical
Schematic to identify the proper terminals for wire connection, and refer to the panel outline
drawing for conduit entry size. Incoming power should be connected to the appropriate
terminal blocks in the control panel as shown by the Electrical Schematic.
