Basic Installation 3-9MN1901
3.4.1 Single-phase connection to package sizes A, B, C, D
Location Connector X1
(Mating connector: Phoenix COMBICON MVSTBW 2,5/9-ST, 5mm pitch)
Part number MDH1A... MDH2A...
Nominal input
voltage
115VAC, 1ฮฆ line to neutral
(U.S. single phase supply)
230VAC, 1ฮฆ line to neutral
(European single phase supply)*
Range 75-125VAC 75-250VAC
* The required 230VAC supply may also be derived from two phases of a U.S. 230VAC
3-phase supply, i.e. 230V AC line to line. Connect one phase to L and the other phase to N.
For single-phase connection, the voltage ripple on the DC-bus is 25Vp-p for 5A peak current
rising to 50Vp-p for 10A peak current. This can limit the maximum speed of the motor .
T ightening torque for terminal block connections is 0.5-0.6Nm (4.4-5.3 lb-in).
The threaded hole in the top of the enclosure is for protective earth/ground connections.
The threaded hole in the bottom of the enclosure may be used as an additional functional
earth/ground connection for signals on connector X3. It may also be used to attach strain relief
clamps. The holes are threaded for M4 bolts no longer than 12mm (0.47 in) in length. Longer
bolts may short circuit the electrical components inside the MintDrive

Note: For CE compliance, a filter must be connected between the AC power supply and
the MintDrive

. If local codes do not specify different regulations, use at least the
same gauge wire for earth/ground as is used for L and N.
