1 Safety information
WARNING
CAUT ION
NOTE
1.1 Warnings, cautions and notes
A Warning contains information, which is essential for avoiding a safety hazard.
A Caution contains information, which is necessary for avoiding a risk of damage to the
product or other equipment.
A Note contains information, which helps to ensure correct operation of the product.
1.2 Electrical safety - general warning
The voltages used in the drive can cause severe electrical shock and/or burns, and
could be lethal. Extreme care is necessary at all times when working with or adjacent to
the drive.
Specific warnings are given at the relevant places in this guide.
1.3 System design and safety of personnel
The drive is intended as a component for professional incorporation into complete
equipment or system. If installed incorrectly, the drive may present a safety hazard.
The drive uses high voltages and currents, carries a high level of stored electrical
energy, and is used to control equipment which can cause injury.
System design, installation, commissioning / start up and maintenance must be carried
out by personnel who have the necessary training and experience. They must read this
safety information and this guide carefully.
The STOP and START controls or electrical inputs of the drive must not be relied
upon to ensure safety of personnel. They do not isolate dangerous voltages from
the output of the drive. The supply must be disconnected by an approved
electrical isolation device before gaining access to the electrical connections.
The drive is not intended to be used for safety-related functions.
Careful consideration must be given to the function of the drive which might result in a
hazard, either through its intended behavior or through incorrect operation due to a
fault. In any application where a malfunction of the drive or its control system could lead
to or allow damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk.
1.4 Environmental limits
Instructions within the supplied data regarding transport, storage, installation and the
use of the drive must be complied with, including the specified environmental limits.

1.5 Access
WARNING
Access must be restricted to authorized personnel only. Safety regulations which apply
at the place of use must be complied with. The IP (Ingress Protection) rating of the drive
is installation dependant.
information
Safety
1.6 Motor
Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of a drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. If necessary, an electric force vent fan should be used.
1.7 Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering.
1.8 Electrical installation
1.8.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
• AC supply cables and connections
• Output cables and connections
• Many internal parts of the drive
Unless otherwise indicated, control terminals are single insulated and must not be
touched.
1.8.2 Isolation device
The AC supply must be disconnected from the drive using an approved isolation device
before any cover is removed from the drive or before any servicing work is performed.
1.8.3 STOP function
The STOP function does not remove dangerous voltages from the drive or the motor.
1.8.4 Ground leakage current
The drive is supplied with an internal EMC filter capacitor installed. If the input voltage to
the drive is supplied through an ELCB or RCD, these may trip due to the ground
leakage current. See section 4.3.1 Internal EMC filter on page 14 for further information
and how to disconnect the internal EMC capacitor.
The VFD66 series variable speed drives are intended to control equipment under normal
operating conditions. Where failure or malfunction of a VFD66 drive could lead to an
abnormal operating condition that could cause personal injury or damage to the
equipment or other property, other devices, (limit or safety controls) or systems (alarm or
supervisory) intended to warn of, or protect against, failure or malfunction of the VFD66
drive must be incorporated into and maintained as part of the control system.

Risk of thermal damage
CAUT ION
CAUT ION
WARNING
WARNING
CAUT ION
The VFD66 control can generate and dissipate significant heat. Mount the control on a
metal, concrete, or cinderblock mounting surface. Mounting the VFD66 control on
surfaces made of wood or other heat-sensitive material may result in damage to the
mounting surface.
Risk of equipment damage
Motors used with the VFD66 controls must meet certain specifications for proper
performance and operation. Motors that do not meet these specifications may be
damaged.
Risk of electrical shock
The printed wiring board and its components are at AC line voltage. Direct or indirect
contact with line voltage can result in personal injury or death.
Risk of electrical shock
The VFD66 drive remains electrically charged for a period of time after the power is
removed. To avoid possible electrical shock, wait at least 10 minutes after AC supply
power has been disconnected from the VFD66 drive before servicing the control. Failure
to wait until the VFD66 drive fully discharges could cause electrical shock, personal
injury, or death.
Risk of equipment damage
Connect each of these items to the VFD66 drive using a separate conduit for each set
of wires:
• Line voltage supply power
• Line voltage output power to motor
• Low voltage signals from input devices
Running different voltage and frequency wires in the same conduit can create electronic
noise or harmonics, which may damage the condenser fan motors.

Enclosure
WARNING
WARNING
The drive is intended to be mounted in an enclosure which prevents access except by
trained and authorized personnel, and which prevents the ingress of contamination. It is
designed for use in an environment classified as pollution degree 2 in accordance with
IEC 60664-1. This means that only dry, non-conducting contamination is acceptable.
The VFD66 drive can generate and dissipate significant heat. Mount the drive on a metal,
concrete or cinder block mounting surface. Mounting the VFD66 drive on surfaces made
of wood or other heat-sensitive material may result in damage to the mounting surface.
Safety information Rating data
Observe the following the guidelines when mounting a VFD66 drive:
• Mount the VFD66 drive on a vertical surface with the heatsink fins oriented vertically
and the conduit holes facing down.
• Provide a minimum of 4 in. (102 mm) clearance around the heatsink.
• Ensure that output power wiring between the VFD66 drive and the motor does not
exceed 50m (165 ft).
Mount the VFD66 drive in a location protected from condensation, explosive vapours,
corrosive gas, water, and dust.
