Planning the electrical installation

Continuous motor cable shield or enclosure for equipment in the motor cable
To ensure safety and minimize the emission level when safety switches, contactors,
connection boxes or similar equipment are installed in the motor cable between the
drive and the motor:
• European Union: Install the equipment in a metal enclosure with 360 degree
grounding for the shields of both the incoming and outgoing cable, or connect the
shields of the cables otherwise together.
• US: Install the equipment in a metal enclosure in a way that the conduit or motor
cable shielding runs consistently without breaks from the drive to the motor.
Implementing thermal overload and short-circuit protection
Protecting the drive and input power cable in short-circuits
Protect the drive with fuses (1) and the input cable with fuses (2) as shown below:
Size the fuses at the distribution board according to local regulations for the input
cable protection. Select the fuses for the drive according to the instructions given in
chapter
.
The fuses for the drive protection will restrict drive damage
and prevent damage to adjoining equipment in case of a short-circuit inside the
drive.
Note 1
: If the fuses for the drive protection are placed at the distribution board and
the input cable is dimensioned according to the nominal input current of the drive
given in the rating table on page
, the fuses will protect also the input cable in
short-circuit situations, restrict drive damage and prevent damage to adjoining
equipment in case of a short-circuit inside the drive. No separate fuses for the input
cable protection are needed.
Note 2:
Circuit breakers must not be used without fuses. For more information,
contact ABB.
Protecting the motor and motor cable in short-circuits
The drive protects the motor cable and motor in a short-circuit situation when the
motor cable is dimensioned according to the nominal current of the drive. No
additional protection devices are needed.
