Installation
Input and Output Connections
The On Board Solutions ProTech-C Series Battery charger offers the simplest of
connections and is highly flexible to accommodate on-board and portable applications.
The ProTech-C employs an IEC AC input connector so no special wiring is necessary.
The output side of the unit houses the quick disconnect DC output connector and inhibit
circuit connector. Also included are the mating quick disconnect connector / cable
assemblies for connecting the ProTech-C DC output and inhibit circuit.
The ProTech-C employs a safety interlock inhibit as a standard feature with every model.
The inhibit connector has 3 output connection points associated with it. They are common
(C), normally open (N/O) and normally closed (N/C) dry contact relay points. This offers
the greatest flexibility if connected to a motor controller. The contacts will change state
from their normal condition once AC power is supplied to the battery charger. Many motor
controller units are different and have different signal requirements. The function of this
signal is to inhibit normal operation of the machine the charger is housed within when
in the charging state. Refer to the motor controller PCB (Printed Circuit Board) requirements
to determine which signal is necessary to inhibit the unit from moving when charging.
The inhibit signal can be configured for many different conditions using the common point
of the relay. The following are some examples:
Examples of Possible Inhibit Connection Methods using Normally Open or Normally Closed
Contacts. Consult with the Motor Controller provider in onboard charger applications to
determine the best method for wiring this circuit.
Note: There are many different types of inhibit operations and potentials for wiring this circuit.

Setup and Operation / Understanding Battery Types
Setup and Operation Continued
Selecting a Charging Profile and Understanding Battery Types
There are three primary types of batteries; Flooded (Lead Acid), AGM (Absorbed Glass
Mat) and GEL Cell (Gelled Electrolyte Lead-Acid). Traditionally, the most common type of
batteries used are Flooded (Lead Acid Batteries).
Almost all GEL Cell Batteries will state that they are GEL Cell on the battery case or labels.
ProTech-C series chargers are designed to allow for the following three (3) battery chemistries.
The most important element in selecting a proper profile is to mate up the voltage selections
available in the 3 profiles to that of the battery based upon the battery manufacturers requirements.
For your convenience, we have incorporated 3 major profiles associated with some of the
most common battery brands. These profiles can be used with many different brands and we
suggest you contact the factory if you are unsure as to which profile to select for your application.
It is very important to select the best match as this will impact total battery cycle life! It is also
fundamentally important to neither over or undercharge your batteries. See the chart on Page
8 for some general recommendations. The Profile Battery Selector switch allows the charger
to be compatible with multiple battery technologies (Flooded Lead Acid, AGM and Gel).
Programmable Absorption Timer Switch
***IMPORTANT!*** If you are unsure about which of the 3 available profiles to choose
from, consult with the factory. Incorrect selection can result in permanent damage and under
or overcharging of the batteries.
NOTE: AGM (Absorbed Glass Mat) batteries are not GEL (Gelled Electrolyte
Lead-Acid) batteries. AGM batteries are charged at different charging profiles
and are not the same
General recommendation for the Absorption Timer Switch is as follows:
