Shielding
1 Pin 1 is intended to allow the connection of the shield to
ground even if the plug connector has a plastic case.
2 OVdc of the RS-485 serial connection too.
3 Lika's EC- pre-assembled cables only
4.3 Ground connection
To minimize noise connect properly the shield and/or the connector housing
and/or the frame to ground. Connect properly the cable shield to ground on
user's side. Lika's EC- pre-assembled cables are fitted with shield connection to
the connector ring nut in order to allow grounding through the body of the
device. Lika's E- connectors have a plastic gland, thus grounding is not possible.
In the specific case pin 1 of M12 connector is specifically intended to allow the
connection of the shield to ground. If metal connectors are used, connect the
cable shield properly as recommended by the manufacturer. Anyway make sure
that ground is not affected by noise. It is recommended to provide the ground
connection as close as possible to the device.
