The derating curves apply under the following conditions:
• Mounting on vertical or horizontal mounting rail
• Devices mounted without distance to each other
• with U up to max. 26.4 V DC

The following section describes the special conditions for the
use of an ESR5-NO-31-24VDC at altitudes greater than
2000 m abovesea level.
Make sure to observe the corresponding device-specific specifi-
cations (technical data, derating, etc.).
The use of the device ESR5-NO-31-24VDC at altitudes higher than 2000 m
above sea leveland up to a maximum of 4500 mabove sea level is
allowed provided that:
1. Rated input voltage V
2. The maximum switching voltage at the relay outputs for enable current
paths 13/14, 23/24, 33/34, 43/44: min. 10 V, max. 250 VAC
and signal current path 51/52: min 5 V, max. 250 VAC is not exceeded
▶ 1.Reduce the maximum ambient temperature for operation by the corre-
sponding temperature derating factor as per the following table.
