5.2 European Standards
178 SIEPYEUOQ2A01G AC Drive Q2A Technical Manual
Figure 5.2 Wiring Diagram for CE Low Voltage Directive Compliance
*1 Connect peripheral options to terminals -, +1, +2, B1, and B2.
WARNING! Electrical Shock Hazard. Use terminals -, +1, +2, B1, and B2 to connect options to the drive. Do not connect
an AC power supply lines to these terminals. Failure to obey can cause death or serious injury.
*2 For circuit protection, the main circuit is separated from the surface case that can touch the main circuit.
*3 The control circuit is a Safety Extra-Low Voltage circuit. Separate this circuit from other circuits with reinforced insulation. Make
sure that the Safety Extra-Low Voltage circuit is connected as specified.
*4 Reinforced insulation separates the output terminals from other circuits. Users can also connect circuits that are not Safety Extra-Low
Voltage circuits if the drive output is 250 Vac 1 A max. or 30 Vdc 1 A maximum.
■ Wire Gauges and Tightening Torques as Specified by European Standards
WARNING! Electrical Shock Hazard. Only connect peripheral options, for example a DC reactor or braking resistor, to terminals
+1, +2, +3, -, B1, and B2. Failure to obey can cause death or serious injury.
