2.6.2 Insulation resistance and voltage resistance in accordance with
EN 60204-1
When measuring the insulation resistance and inspecting the
voltage resistance of the machine/automated system, observe the
following information in order to protect the product from
damage:
• The electronics are connected to the housing ground, in order
to protect against overvoltage.
• For measurements of the insulation resistance in accordance
with EN 60204-1, no voltage levels above the permitted
operating voltage range may be used. In addition, the maximum
measuring current must be safely limited to values below 10mA.
• Before testing the voltage resistance of the machine/automated
system in accordance with EN 60204-1, disconnect the product
from the electric circuits to be tested. This applies to all
connections on the product:
– positive and negative connections of the power and logic
supply
– Fieldbus connections
