7 Top Level Module Removal Instructions
7.1 Before Proceeding
7.1.1 High Voltage Warning
Frequency converters contain dangerous voltages when connected to mains voltage. No disassembly should be attempted with power applied.
Remove power to the frequency converter and wait at least 40 minutes to let the frequency converter capacitors fully discharge. Only a
competent technician should carry out service. Failure to fully discharge capacitors could result in serious injury or death.
ELECTROSTATIC DISCHARGE (ESD)
Many electronic components within the frequency converter are sensitive to static electricity. Voltages so low that they cannot be felt, seen
or heard can be harmful to electronic components. Use standard ESD protective procedures whenever handling ESD sensitive components.
Failure to conform to standard ESD procedures can reduce component life, diminish performance, or completely destroy sensitive electronic
components.
7.1.3 Optional Circuit Breaker or Disconnect Switch
Supplied with a circuit breaker or disconnect switch, the cabinet doors are interlocked. To open the cabinet doors, the circuit breaker and
disconnect switch must be in the OFF position.
NB!
Inverter units contain 2 or 3 inverter modules. Drawings in this section illustrate units with 2 inverter modules. Changes in instructions for units with 3 modules
are noted.
