NOTES:
1 The GFX4-IR T40 product is especially designed for open delta applications, but can control also other load configurations.
2 The GFX4-IR T40 can control a three-phase load closed-delta (Figure 54)
3 The GFX4-IR T40 can control a three-phase load star without neutral (Figure 47)
4 The GFX4-IR T40 can control a three-phase transformer (Figure 48)
5 The GFX4-IR T40 can NOT control all kind of single-phase loads or three-phase with neutral (Figure 40 - Figure 41 - Figure 42 -
Figure 43 - Figure 44 - Figure 45 - Figure 49)
