3.4.2 Single-phase or three-phase power connecti ons
Location Connector X1 (Matingc onnector: PhoenixCOMB ICON
MSTB2,5H C/11-ST-5,08)
Nominalinput voltage 115VACor 230VAC, 1Φor 3Φline to line
Minimuminput voltage 105VAC,1Φor 3Φlinetoline(seeNote*)
Maximuminput voltage 250VAC,1Φor 3Φline to line
Note: * The MicroFlex e100 will operate at lower input voltages, althoughperformance
couldbe impaired. The driv e will trip if the DC-bus voltage falls below 50V or 60% of
theno-load volt age, whichever occurs first.
Forthree phase supplies ,c onnect 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 ex ample L1 and L2.
For CE compliance, an AC filter must be connected between the AC powersupply andthe
MicroFlex e100. If local codes do not specify different regulations, use at least the samegauge
wirefor earth/groundasis usedforL1, L2 and L3.
Tighteningtorque for terminal block connectionsis 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 str ainrelief
clamps. The holes are threaded for M4 bolts no longer than 11mm (0.43 in) in length.
