Connection - Danfoss VLT OneGearDrive Instruction Manual

Electrical Installation

4.3.1 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 as in EN 60034/DIN VDE
4 4
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 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).
•
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.
NOTICE!
Refer to the Instruction Manual for VLT
AutomationDrive FC 302 and VLT
302 to connect the terminals.
Do not connect the OneGearDrive directly to the power
supply.
