Electrical connections 

 

Danger

! 

Supply voltage! 

The  connection  to  the  electric  mains  should  only  be  carried  out  by  qualified  skilled  personnel  and  must 
correspond to the legal provisions in force in your region.   

Prior  to  connecting  the  device,  please  check  the  name  plate  to  avoid  exceeding  the  indicated  values.  The  voltage 
tolerance is +/- 10%.  

The  installer  is  responsible  for  supplying  and  installing  the  power  cable.  Be  sure  to  provide  the  proper  fuses  or 
breakers based on the data information located on the nameplate. 

 

 

 
A residual-current device (RCD) with I

n =0.3A Class B is suggested. The cross section of the power supply cables 

must  comply  with  the  consumption  of  the  dryer,  while  keeping  into  account  also  the  ambient  temperature,  the 
conditions  of  the  mains  installation,  the  length  of  the  cables,  and  the  requirements  enforced  by  the  local  Power 
Provider. 

 

CAUTION! 
Please observe the direction of rotation of the fix speed compressors!  
In this system, the direction of rotation of the fix speed compressors is supervised by a reverse-
phase protector (RPP).  

When this guard is triggered, the DMC50 goes into alarm mode (the status bar flashes red and shows 
alarm n.5 “Compressor Protection”). In the event that the compressor does not run, the direction of 
rotation must be changed by interchanging two phases. These modifications must only be carried out by 
a qualified electrician.

 

Do not by-pass the RPP protector:  If the device is operated with the incorrect direction of 
rotation, the compressor will fail immediately. This will void the guarantee.

 

 

Danger! 

Supply voltage and missing earth connection!

 

Important: ensure that the plant is connected to earth. 

Do not use plug adapters at the power plug.  

Possible replacement of the power plug must only be carried out by a qualified electrician. 

 

Note! 

This dryer is not suitable for employment on IT-systems. 

This dryer is not suitable for employment on grounded-delta systems
