Chapter 2 Installation and Confirmation
2-1 Basic Equipment
The drive needs the several components for the conjunctive operation. These
components are called “basic equipment”, listed in the following:
2-1-1 Power Source: The voltage with three-phase or single-phase of
the power source must meet the drive specifications.
2-1-2 MCCB or NFB: MCCB (Molded Case Circuit Breaker) or NFB (No Fuse
Breaker) can withstand the inrush current at instant power-on and
providing the overload and over-current protection to the drive.
2-1-3 Drive: The rated current of motors are different for the different pole or
rated voltage. Please base on the rated voltage and rated current of
motor to select drive. Do not select the drive only base on the horse
power specification of motor. (please refer to the lists of standard
specifications of drives)
2-1-4 Motor: The specifications of motor are determined from the
requirement. Please be cautious to the motor rated current that must
not exceed the drive current.
Note: CA is only used for three-phase induction motor control, and must not be used
for single-phase motor.
2-2 Environmental Conditions
For the safe operation of the drive, please be cautious to the environmental
conditions where the drive is going to be installed.
2-2-1 AC Power: AC power input must be complied with the AC power input
specification of the drive.(see CA standard specifications)
2-2-2 Location: Due to the heat dissipating requirement during the drive
operation, the drive must keep enough space for heat dissipation. Please
keep the least clearance space when installation. (shown as below
