4.4.5 MC Auxiliary Input Connections (Terminals 8 & 9 or 11 & 12)
The MC Auxiliary Input provides feedback to the OTS-EL
on the current position of the outlet’s
contactor / breaking device. The OTS-EL provides two options for monitoring the MC Auxiliary. The first
option is used in 110VAC control circuits, as shown in Figure 4.11. The second option is to use the MC
AUX 24V input, as shown in Figure 4.12. This input is used with 24VDC or 24VAC control supplies.
The MC AUX 110V and the MC AUX 24V input do not require a load to be present; the voltage input
can connect directly to the input (via the contactor’s auxiliary contact).

NOTE
Either the 110V or 24V auxiliary inputs should be used
– not both at the
same time.
