14.2.1 Leakage current (AC)
The leakage currents are measured without any load on the shaft
and in accordance with EN 61800-5-1:2007.
WARNING
Electric shock
Death or serious personal injury
‐ If the leakage current is greater than 3.5 mA, use a PE
cable with a minimum cross-section of at least 8 AWG
(10 mm
2
), or use 2 separate PE cables with the same
cross section as the power cable.

In the safe state, the input voltage of ST1 and ST2 with reference to
GND must be as follows:
• V

: 1.25 V.
In the operating state, the current flow into ST1 and ST2 must be
within:
• Minimum contact current: 10 mA
• Maximum contact current: 25 mA.
