How to Convert a SmartPack between 3-Phase and Single Phase
This article describes how to convert a SmartPack to between 3-Phase feed and a Single-Phase feed. We define a 3-Phase feed as 3 Hot legs, Neutral and Ground. We define a Single-Phase feed as 2 Hot lets, neutral and Ground.
Both Portable and Wall Mount SmartPacks easily switch from single phase to three phase operation, or vice-versa, by moving the power feed wires from the L2 terminal in the pack to the L1 and L3 lugs on the power board. Each SmartPack ships with a document including illustrations for this purpose.
A quick summary of the wire placements for both modes:
SmartPacks originally wired as three-phase
| L1 | L2 | L3 | |
|---|---|---|---|
| Three-phase | 1A, 1B | 2A, 2B | 3A, 3B |
| Split-phase | 1A, 1B, 2A | none | 3A, 3B, 2B |
SmartPacks originally wired as split-phase
| L1 | L2 | L3 | |
|---|---|---|---|
| Split-phase | 1A, 1B, 1C | none | 2A, 2B, 2C |
| Three-phase | 1A, 2A | 1B, 2B | 1C, 2C |
If wired incorrectly, your SmartPack dimmers may not fade properly or may jump to full when set at a low level. No worries, this just means that you didn't properly configure your pack for single or 3 phase operation.
The SmartPack will operate within a voltage range of 85-140VAC, 47-63Hz. This will allow the SmartPack to be used in countries with a power cycle of 50Hz.
