9.4 Electrical Installation
All work should be carried out with power off.
Electric servo actuators and motors have dangerous live and rotating parts. All work during connection, operation, repair and
disposal must be carried out only by qualified personnel as described in the standards EN 50110-1 and IEC 60364! Before star-
ting 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The measures taken above must only be withdrawn when the work has been completed and the device is fully assembled.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.
Due to the fact that the motor contains permanent magnets, a voltage is generated at the motor terminals when the rotor is
turned.
• The connecting leads should be suitable for the type of use, as well as the voltages and amperages concerned.
• The protective earth must be connected to the terminal marked PE.
• All cables used should be provided with a shield and in addition, the encoder cable should feature twisted pair leads.
• The power supply is switched off before connecting and disconnecting the power connection and signal connections.
Encoders and sensors contain electrostatically sensitive components, observe the ESD measures!
