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
frequency converters in the unit size 6x range.
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 an understanding of the frequency converter operation for 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 designed for fan and pump applications.
AF-650 GPseries frequency converters are fully programmable for either constant torque or variable torque industrial applications. They are capable of operating
a great variety of applications and incorporate a wide range of control and communication options.
These models are available in 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 energized 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.
The following options are powered before the optional circuit breaker or disconnect. Even with the circuit breaker or disconnect in the OFF
position, mains voltage is still present inside the frequency-converter cabinet.
• Door interlock
• Space heater
• Cabinet light and outlet
• RCD monitor
• IRM monitor
• Emergency stop
• 24 VDC customer power supply
If 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.
