Risk of personal injury and property damage from electric shock
• Before working on the unit, ensure that the unit is dead.
• Do not operate the unit with the housing open.
Risk of property damage from wrong supply voltage
• Prior to connecting, measure the supply voltage and check the voltage set
on the transformer inside the unit.
Risk of property damage from wrong supply voltage
• If the unit is converted from 208 V to 240 V, the power output must be lim-
ited to 80 % (see "Basic setting").
The unit is set to a specific supply voltage or voltage range when
delivered.
If the voltage on site differs from the preset supply voltage, damage
may occur.
Prior to connecting the unit, you must measure the supply voltage,
check the transformers in the unit and reposition the connections if
necessary.
