Illustration 8: Terminal Box Screws
N O T I C E
Never alter the position of the terminal box or open any screws unless instructed to in this manual. Doing so can damage the
VLT® OneGearDrive® and invalidate the warranty.
5.3.1 Terminal Box Connection
Ensure that the power is switched off before opening the terminal box. The information on voltage and frequency on the name-
plate must correspond with the mains voltage under observance of the terminal circuit. Exceeding the tolerances as in
EN 60034/DIN VDE 0530, that is, voltages ±5%, frequency ±2%, cam form, and symmetry, increases heating and reduces service life.
Observe any accompanying connection diagrams, particularly for special equipment (for example, thermistor protection). The type
and cross-section of the main conductors, as well as the protective conductors and any potential equalization which may become
necessary, must correspond to the general and local installation regulations. With switching duty, take the starting current into ac-
count.
Protect the VLT® OneGearDrive® against overload and, in dangerous situations, against unintended starts. Lock the terminal box
again to protect against contact with live components.
C A U T I O N
RISK OF SHORT CIRCUITS
Short circuits can occur if water penetrates through the cables into the terminal box. The installed end caps on the terminal box
support the IP protection rating of the VLT® OneGearDrive® (see
4.4 Protection Rating ).
Always use the adequate sealed components when removing the end caps and plugging the wire connection.
Always ensure that the terminal box is closed properly.
N O T I C E
Refer to the Operating Guides for VLT® AutomationDrive FC 302 and VLT® Decentral Drive FCD 302 to connect the terminals.
Do not connect the VLT® OneGearDrive® directly to the supply.
