Cables
The table below is only a guide; refer to local
wiring regulations for correct size of cables. In some cases, a
larger cable size is required to avoid excessive voltage drop.
Use 105°C (221°F) (UL 60/75°C temp rise)
PVC-insulated cable with copper conductors having a suitable
voltage rating, for the following power connectors:
- AC supply to external EMC filter (when used)
- AC supply (or external EMC filter) to drive
- Drive to motor
- Drive to braking resistor Motor cables The recommended output
cable sizes assume that the motor maximum current matches that of
the drive. Where a motor of reduced rating is used, programmed
with the correct motor rated voltage.
Fuses
The AC supply to the drive must be fitted with suitable
protection against overload and short circuits. Tables below show
the recommended fuse ratings. Failure to observe this requirement
will cause risk of fire.
A fuse or other protection device must be included in all live
connectors to the AC supply.
An MCB (miniature circuit breaker) or MCCB (molded case circuit
breaker) with type C tripping characteristics maybe used in place
of fuses as long as the fault clearing capacity is sufficient for
the installation.
Fuse types
Europe: Type G HRC fuses complying with EN60269 parts1 and 2 (BS88)
USA: Bussman Limitron KTK series, class CC fast acting

NOTE 2 The drives require an
optional top cover kit to meet the NEMA 1 requirements. Any
operator-accessible parts will conform to EN61010-1 (Safety
requirements for electrical equipment for measurement, control, and
laboratory use). European installers will apply EN60204-1 to their
control panels, so the drive design will be compatible with
EN60204-1 (Safety of machinery - electrical equipment of machines).
