Chapter 2 - Safety
2.1 Safety Information
The following section describes the safety issues encountered while installing a voice
coil motor and the precautions you can take to minimize risk.
2.2 Before Unpacking
The package contains only Voice coil motor. Each Voice coil motor is carefully
packaged for shipment. When you receive your motor, there are several things you
should do immediately.
•Observe the condition of the shipping container and report any damage
immediately to the carrier that delivered your motor.
•Verify that the part number of the motor received is the same as the part number
listed on your purchase order.
2.3 Installation Environment
The Motor should be installed in an area that is protected from direct sunlight,
corrosives, harmful gases or liquids and metallic particles. Exposure to these can
reduce the operating life and thus degrade performance. Ventilation is extremely
crucial. Be sure that the area for ventilation is not obstructed, as this will limit the air
flow.
Motors will get warm and the heat must be dissipated to prevent damage. Be sure to
allow clearance and access for cleaning, repair, service and inspections. These
motors are water resistant, not water proof. Avoid submersion and contact with
petroleum-based solvents. Do not use these motors in the presence of flammable
atmospheric environment.
Danger from heavy loads!
Lifting heavy load may damage your health
Use a host of an appropriate size when positioning heavy loads!
Observe applicable occupational health and safety regulations
when handling suspended loads!

2.4 Upon Unpacking
Each Akribis voice coil motor is packaged for ease of handling and to prevent entry of
contaminants.
•To avoid condensation inside the motor, do not unpack until the motor has
reached ambient room temperature.
•When the motor has reached ambient room temperature, remove all protective
wrapping material from the motor. Handle all components with care, especially
magnet plates which are sensitive to shocks.
•Always unpack and work on only one motor track at a time.
2.5 Magnet Track Handling
The magnets are exposed and the magnetic flux is very strong. These magnets are
extremely powerful and special precautions need to be taken. Only qualified personnel
should attempt installation, operation and maintenance of electrical equipment.
2.6 Safety Precautionary Notes
•Before installing themotor, make sure thatthe supplymains are
grounded and operate with the safety regulations enforced. Do
not touch electrical connections before you first ensure that
power has been disconnected. Electrical shock can cause
serious or fatal injury.
•Before carrying out checks or doing any maintenance works,
disconnect the supply mains voltage. Be sure that there is no
possibility of accidental events.
•Ensure that there isaneffective protective earth. Make surethat
there is no voltage at the terminals before connecting.
Be careful when sliding themotor from its shipping container. Slide
the motor from the box onto a flat, firm surface to prevent bending.
Bending can damage the windings.

•Any person with metal or electronic medical implants such as
heart pacemaker should refrain from installing or working near
the voice coil motors.
•Use extreme caution when handling the motor tracks as the
magnetic flux is very strong. These large attraction forces are
very strong and cannot be controlled by hands.Handsor fingers
may be severely injured. Restrain other body parts from these
objects to avoid injury by this magnetic attraction.
•Voice coil motors contain powerful permanent magnets which
require extreme caution during handling. When handling
multiple magnet tracks, do not allow the tracks to come in
contact.
•The surface temperature may exceed 50°C, resulting in a series
of burns. Avoid touching the carriage housing during or shortly
after operation.
•Any person installing or working near the voice coil motor
should not have any items such as watch, credit cards, keys,
etc. that could be damaged by the magnetic field.
•Always keep the vicinity around the voice coil motor clear of
metal objects during installation and use non-magnetic tools for
installation.
•Use proper care and procedures that are safe during handling,
lifting, installing, operating and maintaining operations.
Improper methods may cause muscle strain or other bodily
harm.
•Always unpack and work on only one motor track at a time. Do
not try to work on two or more loose magnet tracks.
•The voice coil motor is powered by an amplifier. In case of a
power disruption, this may automatically result in a free run out
of the motor. Ensure precautions to prevent damage on the
motor in the case of such an event.
•The magnets shall never be exposed to temperatures above
80°C. They can become demagnetized at temperatures
exceeding 80°C.
•Wiring, maintenance and inspection work must be done by a
qualified technician.
•If at any time and any situation that there is any doubt about the
safety of voice coil motor, do not use it and contact Akribis
immediately.
