Supply voltage L+/M
Connect the supply voltage to terminals L+ and M. 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 󹪝rmware updates and
during the update.
