The following special conditions for safe use of the S7-1200 must be followed:
●
Install modules in a suitable enclosure providing a minimum degree of protection of IP54
according to EN 60529 and take into account the environmental conditions under which
the equipment will be used.
●
When the temperature under rated conditions exceeds 70° C at the cable entry point, or
80° C at the branching point of the conductors, the temperature specification of the
selected cable should be in compliance with the actual measured temperature.
●
Provisions should be made to prevent the rated voltage from being exceeded by transient
disturbances of more than 40%.
