Grounding Connections
The MISB has built-in electrical surge protection. For the
system to work, the MISB's earth ground terminal (E1)
must be connected to a ground rod that is driven into the
earth.
Important: Use a #10 (6 mm) or #8 (10 mm)
bare wire to connect the controller to the
ground rod or grounding grid.
To connect the ground wire,
1. Feed the ground wire through the large hole at the
bottom of the cabinet.
2. Place the ground wire into the copper earth ground
terminal. Tighten the screw to secure the wire.
In the LX PLUS Controller Cabinet:
• Install the ESP-LX Plus SITE front panel on the LX PLUS
controller. Connect the ribbon cable and two-wire har-
ness from the face panel to the controller’s circuit
board as shown on page 48 of the ESP-LX PLUS
Installation, Programming, & Operation guide.
• Insert the battery into the battery holder on the back of
the faceplate and attach the recharging clip to the
battery.
• Route the six-wire data cable (end with ferrite bead)
through the cable guides on the back of the face panel
to the Remote/Comm connection port.
• Plug the six-wire cable (ferrite bead close to the con-
nector) into the Remote/Comm connector.
