terminals. Never connect three-phase pow er supply to output terminals U/T1, V/T2 and
W/T3. Failure to comply may result in equipment damage.
Install braking resistors at terminals and B2 only. Failure to comply may result in
equipment damage.
Install DC reactor at terminals and , and remove the jumper connected at
and . Never connect this jumper and DC reactor to any other terminals. Failure to
comply may result in short circuit and equipment damage.
Wiring screw s and bolts for main circuit terminals must be screw ed tightly. Failure to
comply may result in equipment damage.
AC 220V signal is prohibited from connecting to other terminals than control terminals
RA, RB and RC. Failure to comply may result in equipment damage.
ATTENTION
Since all adjustable frequency AC drives from GTAKE have been subjected to hi-pot
test before delivery, users are prohibited from implementing such a test on this
equipment. Failure to comply may result in equipment damage.
Signal w ires should be aw ay from main pow er lines to the best of the possibility. If this
cannot be ensured, vertical cross-arrangement shall be implemented, otherw ise
interference noise to control signal may occur.
If motor cables are longer than 100m, it is recommended output AC reactor be used.
Failure to comply may result in faults.
1.1.4 Run
WARNING
Drives w hich have been stored for more than 2 years should be used w ith voltage
regulator to gradually boost the voltage w hen applying pow er to the drives. Failure to
comply may result in equipment damage.
Be sure to implement the w iring as per Section 3.4
before applying pow er to the drive.
Failure to comply may result in equipment damage and/or electric shock hazard.
Be sure to confirm the completion and correctness of the drive w iring and close the
cover before applying pow er to the drive. Do not open the cover after applying pow er.
Failure to comply may result in electric shock hazard.
After applying the pow er, never touch the drive and peripheral circuits no matter w hat
state the drive is under, otherw ise there w ill be electric shock hazard.
Prior to running the drive, make sure there is no person in surrounding area w ho can
reach the motor so as to prevent personal injury.
When the drive is running, foreign bodies should be prevented falling into the
equipment. Failure to comply may result in faults and/or equipment damage.
