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 off 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The measures taken above must only be withdrawn when the work has been completed and the device is fully assembled.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.
