6 Converting the power supply
To operate the MTC 2 in the USA or in Japan, the power supply needs to be changed from 400 V,
50 Hz to 208/204 V, 50/60 Hz.
NOTE
To convert the power supply from 208/204 V to 400 V, the same procedure must be carried out in
the reverse order.
DANGER
The following activities require access to machine parts that are moved or carry dangerous
voltage. Only perform the activity that is described and do not touch any other live or moving parts.
Because of the intermediate circuit capacitors, there are still dangerous voltages in the device up
to 5 minutes after disconnection. You must therefore not work on the device or the intermediate
circuit terminals before an appropriate time has elapsed. The power and control terminals may
also still be live after the motor comes to a standstill.
There is a risk of death, severe injury and/or considerable damage to equipment if these
instructions are not followed.
6.1 Tools and accessories
– 1 set of screwdrivers
