6 Electrical Installation Considerations
6.1 Electrical Installation in General
All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper conductors
are required. 75 °C (167 °F) is recommended.
6.1.1 Fastener Torque Ratings
Table 14: Tightening Torques for Enclosure Sizes H3–H6, 3x200–240 V & 3x380–480 V
6.2 Fuses and Circuit Breakers
Fuses and circuit breakers ensure that possible damage to the drive is limited to damage inside the unit. Danfoss recommends fuses
on the supply side as protection. For further information, see the application note Fuses and Circuit Breakers found on www.dan-
foss.com under Service and support/Documentation/Manuals & guides.
N O T I C E
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.
