2. HARDWARE DESCRIPTION AND INSTALLATION
2.1. Caution Statements
SYMBOLS:
Indicates operating procedures that, if not corr
ectly performed, may cause serious injury
or death due to electrical shock.
Indicates operating procedures that, if not carried out, may cause serious equipment
Indicates important hints concerning the equipment operation.
SAFETY STATEMENTS TO FOLLOW WHEN INSTALLING AND OPERATING THE EQUIPMENT:
1. Always read this instruction manual before starting the equipment.
2.
The ground connection of the motor casing should follow a separate path to avoid
1. ALWAYS PROVIDE PROPER GROUNDING OF THE MOTOR CASING AND THE DRIVE
FRAME.
2. If a differential relay against electric shocks is intended to be used, this must be a
“B-type” differential relay.
3. The drive may generate an output frequency up to 1000 Hz
rotation speed up to 20 (twenty) times the rated motor speed (for 50Hz motors): never
use the motor at higher speed than the max. allowable speed stated on the motor
nameplate.
4. ELECTRICAL SHOCK HAZARD – Never touch the drive electrical parts when the drive
is on; always wait at least 20 minutes after switching off the drive before operating on
the drive.
5. Never perform any operation on the motor when the drive is on.
6. Do not perform electrical connections on the motor or the drive if the drive is on.
Electrical shock hazard exists on output terminals (U,V,W) and resistive braking
module terminals (+, –, B) even when the drive is disabled. Wait at least 20 minutes
after switching off the drive before operating on the electrical connection of the motor
or the drive.
7. MECHANICAL MOTION – The drive determines mechanical motion.
It is the
operator's responsibility to ensure that this does not give rise to any dangerous
situation.
8. EXPLOSION AND FIRE – Explosion and fire hazard exists if the equipment is installed
in presence of flammable fumes. Do not install the drive
explosion and fire hazard, even if the motor is installed there.
