4.4 Earthing and equipotential bonding

If the process connection does not establish an adequate electrostatic ground for the device, a
supplementary ground connection shall be established using the earth screw 1 - 2 - 3 or 4.
The position of the ground terminal is illustrated below. This bond only provides an electrostatic
connection for the device and does not fulfil the requirements for an equipotential connection.

Also ensure that the mounting screws for the indicator are firmly tightened.
