7.7.5.2 Example Wiring Installation for Multiple AMD2000 using STO
When using multiple drives in a machine, the STO wiring may allow daisy chaining to each of the drives as
shown in
Figure 7-19 - Multiple drives STO wiring example .
Warning:
It is the machine builder’s responsibility to ensure the correct design and installation of
the safety systems on a machine for hazard reduction. Such ‘daisy chains’ are not always suitable.
In this example the STO channels are powered from an ex24V DC power supply (see notes in
Table 7-1 -
STO Input Ratings about external power supply requirements and approvals). The voltage rating of the external
power supply should be compatible with the conditions listed in Table 7-1 - STO Input Ratings. Each channel will
draw the current listed in Table 7-1- STO Input Ratings , so the power supply should be sized accordingly taking
into account the number of drives in parallel.

Note: If you are wiring multiple drives together, 24V power requirements must be carefully
considered. If using the AMD2000 internal power supply, be careful not to exceed power supply
current limits (refer to the note at the bottom of section
Table 7-1 - STO Input Ratings ). Failure to
do so may result in activation of over current protection and may therefore cause unexpected STO
activation.
