However, if 15 Flexi Loop nodes are used in the same conditions, the input voltage
dr
ops below the permissible value from the 7
th
Flexi Loop node.

Table 5: Example voltage drop on 15 Flexi Loop nodes
Solution example with PWRI power supply accessory
By using a PWRI po
wer supply accessory after the 11
th
Flexi Loop node, the input volt‐
age is adequate at all Flexi Loop nodes.

Table 6: Example voltage drop on 15 Flexi Loop nodes with PWRI
Solution example with increased wire cross-section
Using a wir
e cross-section of 0.75 mm² will ensure that a sufficient input voltage is
available even at the 15th Flexi Loop node.
