and that the atmosphere around the instrument is settled.
● Make sure the main voltage does not exceed the maximum voltage listed on the product
label.
● Ensure that no more than 8 mm of each wire is stripped (to avoid danger of contact with
live parts).
● Ensure the boots for protecting cable terminations are no longer than 8 mm (to avoid
danger of contact with live parts).
● For installation of the 3-wire PNP electronics (Protection Class III), the insulation of the
connected power supply and output load must meet the relevant standards.
