Number of Edens that can be used with Vital 1
The following table shows the number of Edens that can be connected to Vital 1 with the maximum voltage
variation. The values have been established in a laboratory environment. The actual possible number of connected
Edens may therefore differ from those given in the table. The values should be regarded as guidelines; ABB
JOKAB Safety recommends a maximum of 30 Edens per Vital 1. The table was prepared according to
measurements with connection example A. If connection example B and 0.34 mm

from two directions), the values for 0.75 mm

in the tables are used.
NB: The PFH
