TERMINAL CONNECTION
Connect the unit as in the diagram below.
Be sure to ground the DIN rail on which the unit is mounted and cross-wire between the rail and FG terminal of the protected
device as shown in Figure 1 in order to equalize the earth potential.
When the unit is connected with a device which has no FG terminal, ground the surge protector only.
