SM - SMO MODELS ELECTRICAL CONNECTIONS
Before proceeding to the electrical connections make sure that the available power supply voltage is in
accordance with the data specified in the technical data.
The Active Element must be powered at a 24Vdc±20%
(PELV, in compliance with the standard EN 60204-1 (Chapter 6.4)).
Make sure the connectors are screwed down tightly to ensure correct barrier operation!
In order to ensure the declared Environmental Protection Degree (IP65-IP67), it is mandatory to
protect the unused connectors with the provided protection caps.
PRECAUTIONS
• Make the connection to earth before making any other connections.
• Perform all connections before energizing Safegate.
• The ground connection (0VDC) must be common to all system components.

It is recommended to keep SAFEGATE’s power supply separate from that of other electrical power
equipment (electric motors, inverters, frequency changers) or other sources of disturbance.
Î
For connections more than 20 m long, cables with a section of at least 0.5 mm

must be used
(AWG16), (1 mm
