TARTUP
This section covers basic checks and procedures that should be used when
performing a startup with a M3545P regenerative power supply.
Multiple repeated precharge cycles can damage the M3545's precharge
resistor. Ensure that no more than five precharge cycles take place within a

▪
Verify that the voltage of the AC power system is the same as the unit.
▪
Ensure that all connections are tight and that all wiring is of the proper
size and rating for operation.
▪
Verify continuity of all fuses prior to applying power.
▪
Check for exposed conductors that may lead to inadvertent contact.
▪
Check for any debris, shavings, trimmings, etc. that may cause shorts or
obstruct ventilation on unit.

TARTUP
After completing pre-checks and recommended checks for connected
equipment you may apply power to the system.
▪
The green Power LED should light up and stay on. This indicates that
the regenerative power supply is powered on.
▪
Both red and yellow indicator LEDs should illuminate on the front panel
and the fan should turn on for 3 sec.
▪
The red and yellow LEDs will then toggle once or three times to indicate
how many AC phases the unit has detected.
▪
Finally, the Not Ready and Regen Active LEDs should turn off and the
Ready Output contact will close.
The drive system can now be run normally.

OOLING
The cooling fan runs when the unit is active (braking event), and stays on for
10 minutes after the active event ends. If the unit gets too hot, the fan will
stay running until the unit's internal temperature falls below the threshold.
