2. Safety and Installation Instructions
Please take note of the information and instructions in this document. Specialy designed models may dier in technical de-
tail. If in doubt, we strong recommend that you contact the manufacturer, giving the type designation and serial number for
clarification.
2.1 Hazards
Electric servo actuators and motors have dangerous live and redating parts. All work during connection, operation, repair and
disposal must be carried out by qualified personnel as described in the standards EN50110-1 and IEC 60364! Before starting
any work, and especially before opening covers, the actuator must be properly isolated. In addition to the main circuits, the
user also has to pay attention to any auxilliary circuits.
Observing the five safety rules:
• Disconnect mains
• Prevent reconnection
• Test for absence of harmful voltages
• Ground and short circuit
• Cover or close o nearby live parts
The measures taken above must only be withdrawn when the work has been completed and the device is fully assembled.
Improper handling can cause damage to persons and property. The respective national, local and factory specific regulations
must be adhered to.
The surface temperature of gears, motors and actuators can exceed 55 degrees Celsius. The hot surfaces should not be touched.
Cables must not come into direct contact with hot surfaces.
ADVICE
DANGER
ATTENTION

61018854 12/2015 V01
Electric, magnetic and electromagnetic fields are dangerous, in particular for persons with pacemakers, implants or similiar.
Vulnerable groups must not be in the immediate vicinity of the products themselves.
Built-in holding brakes alone are not functional safe. Particularly with unsupported vertical axes, the functional safety and
security can only be achieved with additional, external mechanical brakes.
The successful and safe operation of gears, servo actuators and motors requires proper transport, storage and assembly as
well as correct operation and maintenance.
Use suitable lifting equipment to move and lift gears, servo actuators and motors with a weight > 20 kg.
Special versions of products may dier in the specification from the standard. Further applicable data from data sheets,
catalogues and oers of the special version have to be considered.
WARNING
ADVICE
INFORMATION
2.2 Intended Purpose
The Harmonic Drive® servo actuators and motors are intended for industrial or commercial applications. They comply with the
relevant parts of the harmonised EN 60034 standards series.
Typical areas of application are robotics and handling, machine tools, packaging and food machines and similar machines.
The servo actuators and motors may only be operated within the operating ranges and environmental conditions shown in
the documentation (altitude, degree of predection, temperature range etc).
Before plant and machinery which have Harmonic Drive® servo actuators and motors built into them are commissioned, the
compliance must be established with the Machinery Directive, Low Voltage Directive and EMC guidelines.
Plant and machinery with inverter driven motors must satisfy the predection requirements in the EMC guidelines. It is the
responsibility of the installer to ensure that installation is undertaken correctly.
Signal and power lines must be shielded. The EMC instructions from the inverter manufacturer must be observed in order
that installation meets the EMC regulations.
DANGER
DANGER

71018854 12/2015 V01
2.3 Non Intended Purpose
The use of servo actuators and motors outside the areas of application mentioned above or, inter alia, other than in the
operating areas or environmental conditions described in the documentation is considered as non-intended purpose.
Direct operating from the mains supply is not allowed.
The following areas of application are, inter alia, those considered as non-intended purpose:
• Aerospace
• Areas at risk of explosion
• Machines specially constructed or used for a nuclear purpose whose breakdown might lead to the emission of radio-activity
• Vacuum
• Machines for domestic use
• Medical equipment which comes into direct contact with the human body
• Machines or equipment for transporting or lifting people
• Special devices for use in annual markets or leisure parks
2.4 Declaration of Conformity
The Harmonic Drive® servo actuators and motors described in the engineering data comply with the Low Voltage Directive.
A copy of the EC conformity declaration is supplied in the appendix.
In accordance with the Machinery Directive , Harmonic Drive® servo actuators and servo motors are electrical equipment
for the use within certain voltage limits as covered by the Low Voltage Directive and thus excluded from the scope of the
Machinery Directive. Commissioning is prohibited until the final product conforms to the Machinery Directive.

Largest hollow shaft
with precision output bearing
CHA Series Hollow Shaft Servo Actuators combine a synchronous servo motor, Unit from the CPU-H Series, feedback sensor
and a high capacity precision output bearing. Available in eight sizes with gear ratios between 30 and 160:1, the actuators can
provide maximum torques from 8 to 1840 Nm. The output bearing with high tilting capacity often allows direct attachment of
heavy payloads without the need for further support, thereby providing simple and space saving design installations.
To adapt to your specific application, the CHA Series oers many possible combinations when selecting the motor winding,
Motor feedback system, brake, various sensors and cable as well as connector options.
The integrated hollow shaft can be used to feed through supply lines or services for additional axes, enabling space saving
designs with minimal installation dimensions required. With a reinforced output bearing oering maximum tilting rigidity,
the actuators can easily absorb and accurately guide heavy payloads. The accurate positioning of the actuator ensures stable
machine characteristics, increased operating reliability and consistent quality. With high predection ratings and corrosion
resistance, the series is perfectly suited for use in harsh and demanding environmental conditions.
By combining the CHA Actuators with the specially adapted YukonDrive® Servo Controllers, it is possible to provide a single
source supply for a pre-configured drive system tailored to suit your application. Alternatively, the flexible configuration of
the actuator ensures compatibility with almost any servo controller on the market.
