General Instructions
To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture, 
direct sunlight or excessive heat from sources such as radiators or spotlights. No user service-
able parts are inside. Repair and maintenance must be carried out by qualified personnel au-
thorized by MUTEC GmbH! The unit has been designed for operation in a standard domestic 
environment. Do NOT expose the unit and its accessories to rain, moisture, direct sunlight or 
excessive heat produced by such heat sources as radiators or spotlights! The free flow of air 
inside and around the unit must always be ensured.
Initial Operation
Prior to the initial operation of the unit, the appliance, its accessories and packaging must 
be inspected for any signs of physical damage that may have occurred during transit. If the 
unit has been damaged mechanically or if liquids have been spilled inside the enclosure, the 
appliance may not be connected to the mains or must be disconnected from the mains im-
mediately! If the unit is damaged, please do NOT return it to MUTEC GmbH, but notify your 
dealer and the shipping company immediately, otherwise claims for damage or replacement 
may not be granted.
If the device is left in a low-temperature environment for a long time and then is moved to 
a room-temperature environment, condensation may occur on the inside and the exterior. 
To avoid short-circuits and flashovers, be sure to wait one or two hours before putting the 
device into operation.
Power Supply
The device contains a self-adapting wide-range power supply supporting the majority 
of global standard line voltages within a range of 90…250 V, with no need for making 
adjustments. Make sure that your line-voltage source provides a supply voltage within the 
specified range. In addition, make sure that the device is properly grounded via the local 
electric installation.
Please use the enclosed power cord (see packaging) to connect the unit to the mains. Switch 
the unit off before you attempt to connect it to the mains. Connect the power cord to the 
unit, then to a standard 3-pin mains outlet. To draw the power cord, never pull on the cable 
but on the mains plug!
The unit must be grounded during operation!
For information on the power-inlet wiring, refer to the »Wiring of connectors« section in the 
appendix. Disconnect the device from the mains when not using it for an extended period!
