2.9 Terminal Box

The cables of motors with and without brakes can be fed into the motor terminal box and then connected.
Illustration 2.4 Terminal Box
The standard position for the motor terminal box is shown in the dimensional drawings for the geared motor

(see 6.6.1 VLT OneGearDrive Standard).
Screw-on terminal boxes are supplied with a metric screw thread as standard.

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 mains voltage under observance of the terminal
circuit. Exceeding the tolerances as 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
®
VLT OneGearDrive Operating Instructions
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 restarting due to inadvertent
starting.
Lock the terminal box again to protect against contact
with live components.
