DC bus. If the DC bus voltage begins to rise, due to the drive trying to brake or an overhauling load, the M3545P will sink energy back to the AC Line. Under motoring conditions, the M3545P rectifies the AC line and supplies power to the drive through its DC bus terminals. -

• 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 3.4.1.2. - Page 16 12 AWG 7 lb-in Note: All power wire should be selected to match or exceed the voltage rating of the M3545P. Ground wiring should be, at smallest, one gauge smaller than the selected power wiring. Figure 3-2: M3545P Power & I/O Connection Location...

Page 17: I/O Wiring
ONFIGURATIONS The diagrams shown in Figure 3-4 and Figure 3-5 illustrate typical connections of the M3545P units with generic VFDs. There are many other configurations that may be applied provided a basic connection criterion is maintained such as: • The AC Line connections should maintain a low impedance path back to the grid. -
Page 18: Figure 3-4: M3545P Power Wiring
• Any capacitive load requires precharge. Ensure that either the load has internal precharge, or that the M3545P unit has a –R option. Units without the –R option do not support precharge of any amount of capacitance. Applying power with no precharge in the system will result in fuse failure, and possible damage to the unit and load. -

ARALLEL 6.3. Tables 6-1 and 6-2 list the maximum watt loss generated by each of the M3545P units. When installing the units in an additional enclosure, consideration should be given to internal temperature rise. The watt loss rating in these tables is based upon the maximum continuous regen capability of each unit. -

M3545P 7.1.1. IZING THE The M3545P unit is sized for the amount of DC bus current, I which it must carry. To obtain the amount of DC bus current needed during deceleration; the load and motor inertias, desired change in RPM, and required stopping time must be known. -
Page 32: Calculating Energy Savings
ALCULATING NERGY AVINGS The M3545P directs energy from the mechanical load to the power distribution line, where the energy is available to other connected loads. These units provide system energy savings over dynamic braking kits, because the net energy required from the distribution system is reduced by the regenerated energy. - Page 33 User’s Manual NOTES...
