All basic control circuit (signal) connections are shown in
the appropriate diagram:
— Figure 1-5 shows connections for external 2-Wire control.
— Figure 1-6 shows connections for external 3-Wire control.
•
Use Class 1 twisted shielded or twisted-pair shielded wire,
20-16 AWG (0.5-1.25 mm
2
), for control circuit leads. Wire size
should be determined considering voltage drop in leads. Connect
shield sheath AT THE GPD 205 END ONLY; the far end should be
dressed neatly and left unconnected.
•
Signal leads must be separated from main circuit leads L1 (R),
L2 (S), L3 (T), T1 (U), T2 (V), T3 (W), MA, MB & MC leads, and any
other power cables, to prevent erroneous operation caused by
noise interference.
•
Lead length should NOT EXCEED 164 feet (50 meters).
