INSTALLATION
1. Verify that all correct components are in hand:
• TWL: This is effectively an assembly that SPDs attach to in a modular format.
• AC voltage SPD: Verify correct voltage and number of phases. This will mount perpendicular over the top of the two DIN
Rails. It is raised on stand offs so that wiring can pass underneath it. We recommend that this SPD be installed last so
it remains out of your way.
• Photocell SPD: Verify correct voltage. This will mount on a DIN Rail inside the TWL.
• Individual Light SPDs: Use a voltmeter to check all voltages to ensure correct SPDs.
• Verify correct voltage. Be aware that some strobe lights are DC voltage. Connecting the wrong SPDs to wrong voltages
will fail SPDs at startup.
Not included with TWL or SPDs:
• Conduit, fittings, wire, hardware, etc.
• 4” copper ground strap & ground connections
• Mounting hardware
• Labeling equipment
2. Identify appropriate mounting location for TWL (See Figure 1)
