1.13.1 Use at altitudes greater than 2000 m above sea level. NN
The use of the device ESR5-BWS-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
N
: 24 VDC (-15%/+10%) is maintained and
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
.

The following section describes the special conditions for the
use of an ESR5-BWS-31-24VDC at altitudes greater than
2000 m abovesea level.
Make sure to observe the corresponding device-specific specifi-
cations (technical data, derating, etc.).
