Baldor E100 manual Single-phase or three-phase power connections, Location, Nominal input voltage

3.4.2 Single-phase or three-phase power connections
	Location	Connector X1 (Mating connector: Phoenix COMBICON
		MSTB 2,5HC/11-ST-5,08)
	Nominal input voltage	115VAC or 230VAC, 1Φ or 3Φ line to line
	Minimum input voltage	105VAC, 1Φ or 3Φ line to line (see Note*)
	Maximum input voltage	250VAC, 1Φ or 3Φ line to line

Note: * The MicroFlex e100 will operate at lower input voltages, although performance could be impaired. The drive will trip if the DC-bus voltage falls below 50V or 60% of the no-load voltage, whichever occurs first.

For three phase supplies, connect supply to L1, L2 and L3 as shown in Figure 3. For single phase supplies, connect the supply and neutral to any two line inputs, for example L1 and L2.

For CE compliance, an AC filter must be connected between the AC power supply and the MicroFlex e100. If local codes do not specify different regulations, use at least the same gauge wire for earth/ground as is used for L1, L2 and L3.

Tightening torque for terminal block connections is 0.5-0.6Nm (4.4-5.3 lb-in). The threaded hole in the top and bottom of the case may be used as an additional functional earth/ground connection for signals on connector X3. They may also be used to attach shield or strain relief clamps. The holes are threaded for M4 bolts no longer than 11mm (0.43 in) in length.
