the auto restart feature which is set by VR6 behind the front faceplate (see figure
13).
NOTE: Dip switch #6 can be useful if you have a Manzanita Micro BMS because
you can momentarily switch it on and the yellow lights on all the regs should come
on. If any do not illuminate, you can use this feature to narrow down which regs are
not communicating with the charger or find bad reg bus communication cables.
NOTE: In mid 2010, a new 4 pin RJ receptacle was added to the front of the charger
allowing for activation of various extra preset voltage and current levels. For more
information please refer to the 8A Control Board section at the end of this manual.
Wiring your Manzanita Micro Charger
Your PFC-20, 30 or 40 charger has two main power cables coming out of the rear of
the case (see final section for older models) The lower cable is for the incoming
power (usually AC from a wall outlet) and the top cable is the charger’s DC output.
Connecting the Charger to the Battery Pack
The DC output cable has a gray SB-50 Anderson connector on it. This SB-50 is
quite common on EV battery chargers and we recommend that you leave this plug
on the cord. The SB-50 connector has clearly marked positive and negative sides.
Of the three DC wires coming out of the charger white is positive, black is negative
and green is an optional vehicle chassis ground connection. Measure the distance
from your most positive battery terminal to your PFC charger’s SB-50 connector. Cut
a #6 AWG or thicker cable to the appropriate length and solder or crimp the
appropriate size SB-50 contact onto one end of the cable. It is recommended that
you use bright orange cable with a good insulation and voltage rating in excess of
your fully charged pack voltage. (Bright orange Carol brand Super Vu-Tron welding
cable is an excellent solution.) Place red heat shrink or red electrical tape around
the cable near each end to clearly designate it as the positive cable and then using
a matching gray SB-50 connector, push the SB-50 contact end of the positive cable
into the positive side of the SB-50 until it clicks and locks in place.
Measure the distance from your most negative battery terminal to your PFC
charger’s SB-50 connector. Follow the same procedure as for the positive side only
use black heat shrink or black electrical tape around the cable near each end to
clearly designate this as the negative cable. Push the SB-50 pin end of this negative
cable into the negative side of the SB-50 until it clicks and locks in place.
