7 H-Frame Size Disassembly and Assembly Instructions
7.1 Electrostatic Discharge (ESD)
CAUTION
Frequency converters contain dangerous voltages when
connected to the main voltage. Never perform any
disassembly when power is applied. Remove power to
the frequency converter, and wait until the frequency
converter capacitors fully discharge. Only a competent
technician must carry out the service.
Many electronic components within the frequency
converter are sensitive to static electricity. Voltages so
low that they cannot be felt, seen, or heard can reduce
the life, aect performance, or completely destroy
sensitive electronic components.
CAUTION
Use correct ESD procedures to prevent damage to
sensitive components when servicing the frequency
converter.
NOTICE
Frame size is used throughout this manual where ever
procedures or components dier between frequency
converters based upon the unit's physical size. Refer to
chapter 1.4.1 Frame Size Denitions to determine frame
size.
