Owner`s manual

NOTE: In mid 2010, a new 4 pin RJ receptacle was added to the front of the charger

allowing for various 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

A PFC-50 or PFC-50B charger built before 2011 should have two main power

cables coming out of the front of the case (as shown in figure 02). The top cable is

for the incoming power (usually AC from a wall outlet) and the lower cable is the

charger’s DC output.

All PFC-75 chargers and all PFC-50 and PFC-50B models produced after 2011

should have panel mount Anderson Power Pole connections on the rear side

instead of the older style front mounted power cables.

Connecting the Charger to the Battery Pack

PFC-50 Battery Pack to Charger Wiring

For rear mount connections please refer to the PFC-75 wiring section that

follows this one. Looking at the front of a pre-2011 PFC-50 or PFC-50B charger,

you will see that the lower DC output cable has a Blue SB-175 Anderson connector

on it. This SB-175 connector is easily obtainable and we recommend that you leave

this plug on the cord. The SB-175 connector has clearly marked positive and

negative sides. Of the three DC wires coming out of the front 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-175 connector. Cut a #4 AWG or thicker cable to the appropriate

length and solder or crimp the appropriate size SB-175 pin onto one end of the

cable. It is recommended that you use bright orange cable with a good insulation

and a 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 blue SB-175 connector, push the

SB-175 pin end of the positive cable into the positive side of the SB-175 until it

clicks and locks in place.

Next, measure the distance from your most negative battery terminal to your PFC

charger’s SB-175 connector. Cut a #4 AWG or thicker cable to the appropriate

length and solder or crimp the appropriate size SB-175 pin onto one end of this

cable. Place black heat shrink or black electrical tape around the cable near each

end to clearly designate it as the negative cable and then push the SB-175 pin end

of this negative cable into the negative side of the SB-175 until it clicks and locks in

place.
