Ac Power Connections - Baldor MotiFlex e100 Installation Manual

3.4.4 AC power connections

Mating connector
1.5 A ~ 16 A models
21 A ~ 33 A models
48 A ~ 65 A models
Nominal input voltage 230 VAC or 480 VAC, 3Φ line to line
Minimum input voltage 180 VAC, 3Φ line to line (see Note)
Maximum input voltage 528 VAC, 3Φ line to line
Note: The MotiFlex e100 will trip if the DC-bus voltage falls below 200 V or 60% of the
no-load voltage, whichever occurs first. The MotiFlex e100 will stop operating if the
DC-bus voltage falls below 150 VDC, unless a 24 VDC control circuit backup supply
is present (see section 3.6).
Connect the supply to L1, L2 and L3 as shown in Figure 8. For CE compliance, an AC filter must
be connected between the AC power supply and the MotiFlex 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. The threaded studs protruding from the top and bottom case flanges can be used as the
earth/ground connection (PE).
For 1.5 A ~ 16 A models, tightening torque for X1 terminal block connections is 0.5-0.6 N·m
(4.4-5.3 lb-in). The 21 A ~ 65 A models use a spring cage connector. For all models, tightening
torque for the flange mounted PE connection is 2.5 N·m (22.1 lb-in).
