-48VDC
J5-6
-48VDC is factory supplied to J5-6.
J5-6 is also factory jumpered to J5-3 (Digital Input #8, minus)
Note: -48VDC is factory supplied to J5-6 which is also factory jumpered to J5-3 (Digital Input #8, minus). A customer provided ESTOP
switch can be connected to J5-4 (Digital Input #8, positive). Note that ground is furnished on J5-5 for a convenient connection to
the other side of a customer provided ESTOP switch. Digital Input #8 is factory configured for the ESTOP function. Customer-
furnished system ground applied to terminal J5-4 (Digital Input #8, positive) activates the ESTOP function. The ESTOP function
shuts down and locks out the rectifiers and opens the LVD’s. When the ESTOP signal is removed, LVD’s close (if battery present).
To restart the rectifiers; turn AC power to the rectifiers OFF, wait 30 seconds or more (until the LEDs on the rectifier extinguish),
then turn AC power to the rectifiers ON. Rectifiers can also be restarted from the ACU+ LCD or WEB Interface menu (via the
Rectifier Reset command, found in the Manual menu in the LCD menus or under the Rectifier Control Tab in the WEB Interface).
