2.9.1 Connection

The terminal box may only be opened once it has been
ensured that the power is switched off. The information on
voltage and frequency on the nameplate must correspond
with the AC line voltage under observance of the terminal
circuit. Exceeding the tolerances defined in EN 60034 / DIN
VDE 0530, i.e., voltages ±5%, frequency ±2%, cam form,
symmetry, increases heating and reduces service life.
Observe any accompanying connection diagrams, partic-
ularly for special equipment (e.g., thermistor protection,
etc.). The type and cross-section of the main conductors, as
well as the protective conductors and any potential equali-
zation which may become necessary, must correspond to
the general and local installation regulations. With
switching duty, take the starting current into account.
Protect the drive unit against overload and in dangerous
situations against automatic restart due to inadvertent
starting.
Lock the terminal box again to protect against contact
with live components.
