Power Module Mounting and Hook-up Instructions

4.
Remove all particles and grit from the heatsink and power substrate
Spread a thin layer of silicone grease on the heatsink, covering the entire area that the power substrate will occupy
Place the power substrate onto the heatsink with the mounting holes aligned and press firmly into the grease
Place the 2XM4 mounting screws and tighten to 1NM torque
External Connections
All input and output control connections are made via a 16-terminal single in line connector J6. Three phase input connections
are made to terminals R,S and T of J1. Inverter output terminal connections are made to terminals U,V and W of J7. Positive
DC Bus and brake IGBT collector connections are available on terminals P and BR respectively of J5. An external power
resistor may be connected between P and BR to dissipate braking energy.
Power-Up Procedure
Upon application of 3-phase input power, PWM inputs must be held high until the protection latch circuitry is reset. To reset
this latch before inverter start-up, RESET pin on J6 connector must be pulled down low for at least 2usec. This will set the
Fault feedback signal on J6 high. PWM input signals may then be actively driven.
