Further information
More guidelines for grounding and shielding can be found in Section 2
SAFETY AND EMC GUIDELINES.
4.3.1.1. Drive Supply Connector (J7)
Warning
The SB1391 is designed to run directly off single-phase or three-phase 85Vac to 265Vac.
DO NOT use 380/400 Vac supply. It will destroy the unit!
Warning
If the SB1391 is intended to be used with a secondary supply circuit, the supply must be
a suitably European Approved power supply.
The Drive Supply connector is a terminal block connector (accepts wires directly).
Use 16 to 14 AWG wire for the Drive Supply connector.
The AC input to the power section can be single-phase or three-phase. Use 85Vac to 265Vac
supply voltage.
VIN1(L), VIN2(N), VIN3 are used for three-phase drive supply.
VIN1(L) and VIN2(N) are used for single-phase drive supply.
Internal protection against over-current and short circuit make it unnecessary to use expensive
external over-current protection devices, such as breakers with adjustable current protection.
