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
at both ends. The frequency inverter instruction manual
indicates 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., shielded cables) is the responsi-
bility of the system’s installers. For systems with adjustable
frequency drives and rectifiers, the manufacturer’s electro-
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 adjustable
frequency drives 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:
•
A voltage tolerance of
±
5 %.
•
An ambient temperature of -4
°
F [-20] to 104
°
F
[40
°
C].
•
Altitudes up to 3,300 ft [1000 m] above sea level.
