INSTALLATION
Pre-Plan your installation. You need to accomplish the following:
▪ Meet all National and Local codes (NEC ® Art. 285 address SPDs, NEC ® Art. 690 addresses
photovoltaic, Canadian Electric Code, Part 1)
▪ Confirm System voltage to SPD voltage
▪ Mount SPD as close to panel or equipment as possible to keep leads short
(long leads hurt performance substantially)
▪ Ensure leads are as short and straight as possible, including ground. If using a breaker, use a
breaker position that is close to the SPD and the panel’s ground
▪ If using a breaker, recommended breaker size is 30A due to 10 AWG conductor
▪ Make sure system is grounded per NEC ® and clear of faults before energizing SPD
(inadvertent system problem may fail SPD)
▪ Never Hi-Pot test Any SPD (will prematurely fail SPD)
1. Ensure correct SPD; use voltmeter to check voltages as appropriate. (See Figure 1 for wire-outs).
2. Determine Mounting method (see Figure 4) – weather resistant equipment may be required.
3. Remove power from panel/source. Confirm panel/source is deenergized.
4. Identify breaker location and SPD location. Position SPD such that LED is best visible.
5. Mount SPD – weather resistant applications require additional sealing, o-rings, etc. (see Figure 3).
6. Connect conductors as appropriate - 1000V models require insulated sleeving, included
(See Figure 1 for wire-outs) – short & straight as possible (see Figure 2).
7. Label or mark conductors as appropriate (ground: green, positive: red, negative: black).
8. Make sure system is grounded per NEC ® or CEC and is clear of hazards or faults before energizing.
9. Energize and confirm proper operation of green LED indicator. Be aware that LED requires sufficient
voltage to operate. Photovoltaic applications with low light may not generate enough power to
illuminate the LED.
