Supply voltage L+/M
Connect the supply voltage L+ to the L+ and M terminals. An internal protective circuit protects
the I/O module from reverse polarity. The I/O module monitors whether the supply voltage is
connected and present.
Firmware update
The supply voltage L+ must be available on the I/O module at the start of firmware updates
and during the update.
