1. Turn off all power supplying this equipment before working on or
inside equipment.
2. For mounting, see Figure 1.
3. Confirm SPD is rated for your system by comparing voltage
measurements to the Line Voltage (L-L, L-N) on the product label.
4. Confirm the black wires are connected to line wires, the white wire
to the neutral wire and green wire to ground (see figure 2). For the
5. Twist conductors 1/2 turn or more for every 12 inches of length.
6. Keep conductor length as short as possible with no sharp bends.
7. Do not loop or coil wires.
8. Use on solidly grounded systems only.
