xx = 05, 10; yyy = 120, 240, 277, 347, 480
LSP10yyySX3316, for Class II equipment
yyy = 120, 240, 277, 347, or 480
Ungrounded SPDs are suitable for Class II equipment.
Grounded SPDs are suitable for Class I equipment like:
1. Grounding wire comes with power wires from power distribution panel (TN network)
2. No grounding wire is provided; however, the pole has its own solid grounding to the soil.
(TT network)
Installation Guide
• Caution—Risk of electric shock
• Caution—Installation and service must be performed by qualified personnel.
• Caution—Remove ALL electrical power before installation or service.
• Keep wires as straight as possible.
• Round wires rather than bending them at a hard 90 degree angle.
• Connect wires as shown in diagrams.
• Keep wires from the luminaire’s terminal block to the AC/DC power supply as short as possible
so that SPD is close to the AC/DC power supply.
• Do not cross/overlap protected wires (after SPD, AC or DC) with unprotected wires
(before SPD, AC)
• Ensure electrical connections and mountings are correct before energizing the circuit.
