1. Turn off all power supplying this equipment before working on or inside any
enclosure containing this equipment.
2. Identify proper location for surge protective device. Locate as close as possible
to the panel being protected. Mount unit securely, as close to the electrical
connection as possible. See Figure 2 for mounting instructions.
NOTE: The surge protective device must be installed in an accessible location
(not within walls).
3. Confirm surge protective device is rated for your system by comparing voltage
measurements to the Line Voltage (L-L, L-N) on the product label.
4. Install in accordance with National and Local Electrical Codes and match
branch circuit breakers to the size of wire being used (up to 30 A circuit
breaker).
5. Confirm that the electrical terminals used to attach this device are identified for
these conductors.
6. Twist conductors 1/2 turn or more for every 12 inches of length.
7. Do not loop or coil wires. Be sure to maintain adequate wire bending space per
NFPA 70 2002 Edition, article 408.35.
8. Use on solidly grounded systems only.
Diagnostic Operation
•
LED ON = Normal operation
(see Figure 3)
•
LED OFF (one or more) = Fault.
