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 correspond to the consumption of the dryer. In this respect, the ambient temperature, the cable laying
conditions, the length of the cables and the requirements of the local electricity supplier need to be considered.
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.
