Power Terminal Block Specifications
1 Wire sizes given are maximum/minimum sizes that terminal block will accept - these are not
recommendations. Use Copper wire only. Wire gauge requirements and recommendations are based
on 75 degree C. Do not reduce wire gauge when using higher temperature wire.
Motor Cables
A variety of cable types are acceptable for drive installations. For
many installations, unshielded cable is adequate, provided it can be
separated from sensitive circuits. As an approximate guide, allow a
spacing of 0.3 meters (1 foot) for every 10 meters (32.8 feet) of
length. In all cases, long parallel runs must be avoided. Use cable with
the appropriate insulation class.
The cable should be 4-conductor with the ground lead being
connected directly to the drive ground terminal (PE) and the motor
frame ground terminal.
Shielded Cable
Shielded cable is recommended if sensitive circuits or devices are
connected or mounted to the machinery driven by the motor. The
shield must be connected to both the drive ground (drive end) and
motor frame ground (motor end). The connection must be made at
both ends to minimize interference.
If cable trays or large conduits are to be used to distribute the motor
leads for multiple drives, shielded cable is recommended to reduce or
capture the noise from the motor leads and minimize “cross coupling”
of noise between the leads of different drives. The shield should be
connected to the ground connections at both the motor and drive end.
Armored cable also provides effective shielding. Ideally it should be
grounded only at the drive (PE) and motor frame. Some armored
cable has a PVC coating over the armor to prevent incidental contact
with grounded structure. If, due to the type of connector, the armor is
grounded at the cabinet entrance, shielded cable should be used
within the cabinet if power leads will be run close to control signals.
In some hazardous environments it is not permissible to ground both
ends of the cable armor because of the possibility of high current
circulating at the input frequency if the ground loop is cut by a strong
magnetic field. This only applies in the proximity of powerful
electrical machines. In such cases, consult factory for specific
guidelines.
