GE Industrial Solutions AF-600 FP High Power (460V_575V 150HP and above) - Manual (Page 2)

1 Introduction
1.1 Purpose
The purpose of this manual is to provide detailed technical information and instructions to enable a qualified technician to identify faults and perform repairs on
Drives series frequency converters in the 4x and 5x frames.
It provides the reader with a general view of the unit's main assemblies and a description of the internal processing. With this information, technicians should
have a better understanding of the frequency converter's operation to assist in troubleshooting and repair.
This manual provides instructions for the frequency converter models and voltage ranges described in the tables on the following page.
1.2 AF-6 Product Overview
AF-600 FP series frequency converters are designed for the HVAC markets. They operate in variable torque mode or constant torque down to 15 Hz and include
special features and options well suited for fan and pump applications within the HVAC market.
AF-650 GP series frequency converters are fully programmable for either constant torque or variable torque industrial applications. They are full-featured frequency
converters capable of operating a myriad of applications and incorporating a wide variety of control and communication options.
These models are available in Chassis/IP00, NEMA 1/IP21 or NEMA 12/IP54 enclosures.
1.3 For Your Safety
Frequency converters contain dangerous voltages when connected to mains. 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 mains are energised at rated
voltage. Use extreme caution when conducting tests in a powered frequency converter. Contact with powered components could result in
electrical shock and personal injury.
1. DO NOT touch electrical parts of frequency converter when connected to mains. After disconnecting from mains, wait 20 minutes before touching any
components in 4x-frame size units or 40 minutes for 5x-frame size units. See the label on the front of the frequency converter door for specific discharge
time.
2. When repair or inspection is made, mains must be disconnected.
3. The STOP key on the keypad does not disconnect mains.
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 sensitive components.
1.4 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 reduce
the life, affect performance, or completely destroy sensitive electronic components.
