Overvoltage
protection
The power supply is unstable and deviates from
the values on the nameplate by more than
10%
Connect the device to a power
supply conforming to the data on
the nameplate.
Power supply is too low or load is too high
Disconnect unnecessary loads in
the same grid from the power
supply.
Voltage at the mainboard is higher than the
overvoltage protection value
Contact Trotec
The inside of the device is heavily contaminated Contact Trotec
Air inlet or air outlet is blocked
Remove any foreign objects and
dirt from the air inlet and outlet.
Observe the minimum distances
specified in the technical data.
The fan does not run or runs too slowly Contact Trotec

housing is very high, compressor makes
unusual noises or refrigerant leaks
Disconnect the device from the
power supply and contact Trotec.
