5 Electrical Installation

5.1 EMC-Compliant Installation

To guarantee electromagnetic compatibility (EMC) as defined in EMC Directive 2014/30/EU, all signal lines must use shielded cables.
The drive Operating Guide indicates whether a shielded cable is necessary for the motor supply line.
Adhere to the following instructions:
• Ground the cable sheath at both ends.
• Ensure that hybrid cables are double-shielded.
• Always use shielded cables when laying signal cables and power cables parallel to each other.
• Ensure that the cable shields are connected to the terminal box.
-
When using a brake option, use a drive with a mains filter.
The operation of the low voltage machine in its intended application must meet the protection requirements of the EMC (electro-
magnetic compatibility) Directive 2014/30/EU. Correct installation (for example, shielded cables) is the responsibility of the system's
installers. For systems with drives and rectifiers, the manufacturer's electromagnetic compatibility information must also be consid-
ered. The electromagnetic compatibility directive in accordance with IEC/EN 61800-3 is complied with given proper use and installa-
tion of the VLT® OneGearDrive®. This is also true in combination with Danfoss drives and rectifiers.

5.2 Electrical Connection

When connecting the motor, take note of the nameplate data, 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:
• A voltage tolerance of ±5%.
• An ambient temperature of –20 °C to +40 °C (–4 °F to +104 °F).
• Altitudes up to 1000 m (3280 ft) above sea level.

5.3 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.
