Cabling Your ERX System

Cabling the system takes only a few minutes. You need these items:
• A 1/8" flathead screwdriver – to connect the alarm leads
• A 3/8" wrench or 3/8" nut-driver – to loosen and tighten hex nuts on
Power A and Power B leads
• A No. 2 Phillips screwdriver – to remove the power input module
cover
• Two ground wires – we recommend a minimum of 10-AWG ground
wire with a ring-style terminal.
• A #10 kep nut to connect the ground (earth) wire to the ground
terminal.
We recommend that you use shielded cables where appropriate and
perform the cabling tasks in this order:
1
