shocks, heart failure and fatal injury.

Work in the switch cabinet is only to be
performed by qualified electricians or au-
thorized personnel under the supervision
of a qualified electrician.

Adjust to the local voltage according to the enclosed
circuit diagram.
The test stand may only be connected to a grounded
symmetrical three-phase AC system at the preset local
voltage ±10% and a rated frequency of 50/60 Hz.
The protective conductor wire must have a cross-sec-
tion of at least 10 mm².
i
If the MGT measuring system and a 60 Hz mains
frequency are used, the jumper on the terminal strip
in the controll cabinet must run from 161 – 162 to
