2) The internal circuits are shown below. While it is possible to switch either the AC or DC
side of the brake power supply, it is normally safer to switch the AC side. If the DC side is
to be switched, install a surge suppressor near the brake coil to prevent the surge volt-
ages due to switching the DC side damaging the brake coil.
