4 Electrical Installation

4.1 EMC-compliant Installation

To guarantee electromagnetic compatibility (EMC) as
defined in EMC Directive 2004/108/EC, all signal lines must
use shielded cables. The cable sheath must be grounded
4 4
at both ends. The frequency inverter operating instructions
indicate whether a shielded cable is necessary for the
motor supply line. A shielded motor cable is not required
when connecting to a frequency inverter with an output
filter. Always use shielded cables when laying signal cables
and power cables parallel to each other.
The operation of the low-voltage machine in its intended
application must meet the protection requirements of the
EMC (electromagnetic compatibility) Directive 2004/108/EC.
Correct installation (e.g. screened cables) is the responsi-
bility of the system's installers. For systems with frequency
converters and rectifiers, the manufacturer's electro-

4.3 Terminal Box

Feed the motor cables (motor with or without brakes) into the motor terminal box and connect them.
Ensure a perfect seal when closing the terminal box.
Illustration 4.1 Terminal Box
CAUTION
Never alter the position of the terminal box or open any screws unless instructed to in these operating instructions.
Doing so may cause damage to the OneGearDrive and will invalidate the warranty.
Screw-on terminal boxes are supplied with a metric screw thread as standard.

magnetic compatibility information must also be
considered. The electromagnetic compatibility directive in
accordance with IEC/EN 61800-3 is complied with given
proper use and installation of the OneGearDrive. This is
also true in combination with Danfoss frequency
converters and rectifiers.

4.2 Electrical Connection

When connecting the motor, take note of the data on the
nameplate, the connection diagram and the relevant safety
regulations and rules for the prevention of accidents.
Unless a special design is concerned, the data on the
nameplate refers to:
