Power supply wiring
The ground (GND) and “SUP–“
terminals are connected
internally to the ground terminal
and to the module enclosure.
Connect the screw terminal on
the end plate to ground for surge
protection.
Refer to user manual for RF duty
cycle derating when powering
the module from SUP+ and SUPterminals.
