2. Safety and Installation Instructions
Please take note of the information and instructions in this document. Specially designed models may dier in technical
detail. If in doubt, we recommend to contact the manufacturer, giving the type designation and serial number for
clarification.
2.1 Hazards
DANGER
Electric servo actuators and motors have dangerous live and rotating parts. All work during connection, operation, repair and
disposal must be carried out by qualified personnel as described in the standards EN 50110-1 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The measures taken above must only be withdrawn when the work has been completed and the device is fully assembled.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.
ATTENTION
The surface temperature of products exceed 55 degrees Celsius. The hot surfaces should not be touched.
ADVICE
Cables must not come into direct contact with hot surfaces.
DANGER
Electric, magnetic and electromagnetic fields are dangerous, in particular for persons with heart pacemaker, implants or
similiar. Vulnerable individuals must not be in the close proximity of the product.
DANGER
Built-in holding brakes are not functional safe by themselves. Particularly with unsupported vertical axes, functional safety
can only be achieved with additional, external mechanical brakes.

71021387 12/2018 V02
DANGER
Danger of injury due to improper handling of batteries.
Observing of the battery safety rules:
• do not insert batteries in reverse. Observe the + and - marks on the battery and on the electrical device
• do not short circuit
• do not recharge
• do not open or deform
• do not expose to fire, water or high temperature
• do not leave discharged batteries in the electrical device
• keep batteries out of reach of children. In case of ingestion of a battery, seek medical assistance promptly.
WARNING
The successful and safe operation of products requires proper transport, storage and assembly as well as correct operation
and maintenance.
ATTENTION
Use suitable lifting equipment to move and lift products with a weight > 20 kg.
INFORMATION
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.
2.2 Intended Purpose
Harmonic Drive® Products are intended for industrial or commercial applications.
Typical areas of application are robotics and handling, machine tools, packaging and food machines and similar machines.
The products may only be operated within the operating ranges and environmental conditions shown in the documentation
(altitude, degree of predection, temperature range, etc).
Before commissioning of plants and machinery including Harmonic Drive® Products, the compliance with the Machinery
Directive must be established.
2.3 Non Intended Purpose
The use of products outside the areas of application mentioned above or beyond the operating areas or environmental
conditions described in the documentation is considered as non-intended purpose.

81021387 12/2018 V02
2.4 Use in Special Application Areas
The use of the products in one of the following application areas requires a risk assessment and approval by
Harmonic Drive AG.
• 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
• Household devices
• Medical equipment
• Devices which interact directly with the human body
• Machines or equipment for transporting or lifting people
• Special devices for use in annual markets or leisure parks
2.5 Declaration of Conformity
2.5.1 Gears
Harmonic Drive® Gears are components for installation in machines as defined by the Machinery Directive.
Commissioning is prohibited until the end product conforms to the provisions of this directive.
Essential health and safety requirements were considered in the design and manufacture of these gear component sets.
This simplifies the implementation of the Machinery Directive by the end user for the machinery or the partly completed
machinery. Commissioning of the machine or partly completed machine is prohibited until the end product conforms to the
Machinery Directive.
2.5.2 Servo Actuators and Motors
The Harmonic Drive® Servo Actuators and Motors described in the engineering data comply with the Low Voltage Directive.
In accordance with the Machinery Directive, Harmonic Drive® Servo Actuators and 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.
According to the EMC directive Harmonic Drive® Servo Actuators and Motors are inherently benign equipment, unable to
generate electromagnetic disturbance or to be aected by such disturbance.
The conformity to the EU directives of equipment, plant and machinery in which Harmonic Drive® Servo Actuators and Motors
are installed must be provided by the user before taking the device into operation.
Equipment, plant and machinery with inverter driven motors must satisfy the protection requirements of the EMC directive.
It is the responsibility of the user to ensure that the installation is carried out correctly.

3. Technical Description
3.1 Product Description
The SHG-2UH Series Units are available in ten sizes with gear ratios of 50, 80, 100, 120 and 160:1 oering repeated peak
torques from 23 to 3419 Nm.
The integrated output bearing with high tilting capacity enables the direct attachment of heavy payloads without the need
for further support, ensuring a simple and space-saving design.
The SHG-2UH Unit is fully sealed with a large hollow shaft diameter to feed through supply lines, shafts or cables for further
drive systems. The gears cover a wide torque range and feature a long service life, confirmed by many years of successful
service.
The SHG-2SH and -2SO Simplicity Units are very short and lightweight. The absence of input and output flanges means ma-
ximum flexibility in design integration. The -2SH version comes with a large hollow shaft and the -2SO versions is delivered
with a standard Wave Generator.
