Connection - Danfoss VLT OneGearDrive Instruction Manual

Electrical Installation
NOTICE!
Never alter the position of the terminal box or open any screws unless instructed to in this instruction manual. Doing so
can damage the OneGearDrive and invalidate the warranty.
Screw-on terminal boxes are supplied with a metric screw thread as standard.

4.3.1 Connection

Ensure that the power is switched off before opening the
terminal box. 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 as in EN 60034/DIN VDE 0530, that is, voltages
±5%, frequency ±2%, cam form, symmetry, increases
heating and reduces service life.
Observe any accompanying connection diagrams, partic-
ularly for special equipment (for example, thermistor
protection, etc.). 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 account.
Protect the OneGearDrive against overload and, in
dangerous situations, against unintended starts.
Lock the terminal box again to protect against contact
with live components.

CAUTION
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
OneGearDrive (see also chapter 3.3 Protection Rating).
