1.3 For Your Safety
Adjustable frequency drives contain dangerous voltages when connected to line
power. Only a competent technician should carry out service.
For dynamic test procedures, main input power is required and all devices and power
supplies connected to line power are energized at rated voltage. Use extreme cau-
tion when conducting tests in a powered adjustable frequency drive. Contact with
powered components could result in electrical shock and personal injury.
1.
DO NOT touch electrical parts of the adjustable frequency drive when connected to line
power. After disconnecting from line power, wait 20 minutes before touching any com-
ponents in D-frame size units or 40 minutes for E-frame size units. See the label on the
front of the adjustable frequency drive door for specific discharge time.
2.
When repair or inspection is made, line power must be disconnected.
3.
The STOP key on the control panel does not disconnect line power.
4.
During operation and while programming parameters, the motor may start without
warning. Activate the STOP key when changing data.
When performing service, use proper ESD procedures to prevent damage to sensi-
tive components.
1.4 Electrostatic Discharge (ESD)
Many electronic components within the adjustable frequency drive are sensitive to static electricity.
Voltages so low that they cannot be felt, seen or heard can reduce the life, affect performance,
or completely destroy sensitive electronic components.
