To modify the terminal bridge configuration to the motor, configure the terminal bridges for the desired voltage
(208 V, 230 V or 460 V) according to the diagram below. The terminal bridges (1) can be easily removed
using a pair of pliers. Additional terminal bridges are provided with the compressor. The connections for 230
V are the factory standard.
Locate the yellow voltage labels provided with the compressor. Replace the existing label with the appropriate
voltage label (200 - 208 V, 230 V or 460 V).
Compressor status indication on compressors equipped with an Elektronikon® controller
The Elektronikon regulator is provided with an auxiliary relay (K05) for remote indication of a shutdown.
Maximum load for the contacts: 10 A / 250 V AC. Stop the compressor and switch off the voltage before
connecting external equipment. Consult Atlas Copco.
