GENERAL
The MPXS range of compressed air dryers have the provision for dual voltage operation at either 110V 50/60Hz
or 230V 50/60Hz. This is not an automatic process and the selector switch inside the control enclosure must be
set to the correct position before switching on for the first time.
The dryer must be powered from an externally fused electrical supply.
The suggested electrical supply cable is 3 core 1.5mm
The dryer must be earthed/grounded.
ELECTRICAL CONNECTION (See Figure 4)
Open the control shroud (9 - Figure 2) and locate the control enclosure (See Figure 4 for general appearance).
Remove a blanking grommet from one of the shroud supports and feed the main supply cable (1) through so it
exits the dryer body. Connect the cable to a suitable rated AC supply with means of external fused isolation.
OPTIONAL CONNECTION
For remote fault indication, a volt free relay (3) is provided. To access this feature remove the lid.
cable through the unused hole in a shroud support and through the unused gland (4) into the control enclosure.
Terminate the cable with suitable crimp terminals and connect to the relay to achieve the desired signal. Tighten
the cable gland and replace the box lid.
In normal operation, the relay is permanently energised and will de-energise in the event of a power failure or
fault condition. The relay is designed to provide a fault signal and is rated at 250VAC, 1A maximum.
