DANGER!
•
Check polarity and use shielded cables.
• The transmitter housing and shield must be grounded.
• Place the shielding on the control side to ground across a large area to ensure the best
possible protection against electromagnetic interference.
For field housing versions, place the shield evenly on the contact surface of the cable
feedthrough.
• Avoid potential differences between the transmitter housing and the control if at all possible.
To comply fully with PELV requirements in accordance with EN 60204-1 §6.4.1, connect 0 V
(ground) to a point in the system with protective earth.
