the cable to agree with the protection. If 3 or more cables are used in parallel for larger AC drives, use a separate overload protec-
tion for each cable.
6.1.2 UL Standards on Cabling
To comply with the UL (Underwriters Laboratories) regulations, use a UL-approved copper wire with a minimum heat resistance of
60 °C or 75 °C (140 °F or 167 °F).
The cable must be suitable for use on a circuit that gives a maximum of 100 000 rms symmetrical amperes, and a maximum of 600 V.
Use Class 1 wire only.
For the tightening torques of the terminals, see
6.1.3 Cable Selection and Dimensioning
Find the typical sizes and types of cables used with the AC drive in the tables in
refer to local regulations, cable installation conditions, and cable specification.
The dimensions of the cables must comply with the requirements of the standard IEC60364-5-52.
•
The maximum ambient temperature is +30 °C.
•
The maximum temperature of the cable surface is +70 °C.
•
Use only motor cables with a concentric copper shield.
•
The maximum number of parallel cables is 9.
When using parallel cables, make sure to obey the requirements of the cable cross-sections.
For important information on the requirements of the grounding conductor, see
For the correction factors for each temperature, see the standard IEC60364-5-52.
6.1.4 Fuse Selection
We recommend the fuse type aR (UL recognized, IEC 60269-4). To make a selection of the fuse voltage rating, refer to the mains.
Refer also to local regulations, cable installation conditions, and cable specification. Do not use larger fuses than what is recommen-
ded.
External fuses in the input line are required for overload and short-circuit protection of the drive.
Find the recommended fuses in tables in
6.1.5 Principle of the Power Unit Topology
The principles for mains and motor connections of the basic 6-pulse drive in enclosure sizes FR10 to FR14 show in
Some units built in enclosure size FR11 have double input devices and require an even number of supply cables but an uneven
number of motor cables can be used.
Units built in enclosure size FR12 consist of two power units and require an even number of supply and motor cables. See
tion 24
and the tables in
12.4 Cable and Fuse
The 12-pulse drives always have a double set of inputs. The motor connection is size dependent as described in
