POWER SUPPLY
A fused switching isolator must be installed to the main incoming power supply, external to the X4I. The isolator must be fitted with a properly sized fuse to provide adequate protection to the power supply cable used (in accordance with local electrical and safety regulations).

Ensure that the voltage select input is properly jumpered for the incoming power. Default voltage configuration is 230Vac.
PRESSURE SENSOR LOCATION
The system pressure sensor (P) must be located where it will see the air pressure that is common to all of the compressors.

Pressure Sensor Located Before Cleanup Equipment
Dry side pressure will be lower than the system pressure due to pressure differential losses across air treatment equipment. The nominal system pressure will reduce as the air treatment differential pressure increases.

Equipment
Ensure each compressor is equipped with independent excess pressure shutdown. An increase in pressure differential across air treatment equipment can result in excess compressor discharge pressure.
Regular routine monitoring of pressure differential across air treatment equipment is recommended.
