The following section describes the special conditions for the
use of an ESR5-NE-51-24VDC 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-NE-51-24VDC 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
The maximum switching voltage at the relay outputs for
2.
enable current paths 33/34, 43/44, 53/54, 63/64 and the
feedback current path 11/12: min. 10 V, max. 250 VAC
and signal current path 71/72: 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.
