A Appendix: Inline: Additional information

A 1 Use of Inline terminals at an elevation of more than

3000 meters

This section applies to terminals of the Inline product group that are operated with a DC

voltage of < 60 V DC.

WARNING: Dangerous contact voltage/loss of safety function

This section does not apply to the following modules or applications:

– Terminals that are not operated with PELV (Protective Extra Low Voltage) (e.g.

120 V or 230 V)

– Terminals with safety functions (e.g. SafetyBridge, Profisafe)

– Use of a safe signal path

– Use in potentially explosive areas (IEC Ex, ATEX, Hazardous Location).

– XC variants

In these cases, consider the individual terminal or application separately.

The Inline terminals are approved for use up to an elevation of 3000 m above sea level,

see “Technical data for Inline” on page 154.

The maximum permissible ambient temperature decreases at elevations above this level.

Therefore, keep temperature derating in mind when using the terminals at an elevation

greater than 3000 m up to 5000 m.
