All power and user I/O wiring connections are brought out to the terminal block in the
front face of the unit; there should be no need to open the chassis during installation.
Be sure to review all pertinent AC drive and system documentation as well as the
information listed below before proceeding. Connection points and terminal numbers
of the AC drive will be found in the documentation provided with those units.
See Tables 3-1 and 3-2 and Figures 3-2 through 3-5 for connection details.

impedance to return power to the grid.
• Do not install any external chokes or reactors between the M3545P and
the power source; the M3545P has an internal 5% reactor.
• A properly rated isolation transformer may be installed between the
M3545P and the power source, if desired.
• Do not connect to a generator unless minimum load at any time exceeds
the peak expected regen power.
• The M3545P units are not phase sensitive.
• The AC Line connections should have short-circuit current protection.
See Table 6-3.
• To use the M3545P on a single-phase AC grid, you MUST connect to AC
L1 (TB-1) and AC L2 (TB-2).
DC B

• The DC bus connections may be made to the DC bus of an AC drive, the
DC output of a diode sharing unit, or to a common DC bus.
