OPM-155/A

current is limited to 10 Amps at a voltage of up to 14/27 

Volts. The yellow LED will be on constantly during this 

stage. When the charging rate drops to 2.5 Amps, the 

charge will enter the ABSORPTION charging mode. During 

this mode, the yellow LED will be flashing. The charging 

voltage is held at 14/27 Volts and the charging rate 

gradually reduces the amount of current (Amps) flowing to 

the battery to 100% charged state. The battery can be left 

on this mode indefinitely. During this mode, the green LED 

will be on constantly. 

This charger is mounted under the customer connection 

on the control side of the generator and plugged into the 

receptacle mounted in the AC connection cabinet. The 

battery charger receptacle is to be powered by a GFCI 

circuit and installed in accordance with the United States 

National Electric Code. It is suggested that this circuit be 

fused for 15 amps. 

MOUNTING THE AUTOMATIC 
TRANSFER SWITCH

WARNING: FIRE HAZARD

All wiring must be done by a licensed electrician, and 

must conform to the National Electrical Code and 

comply with all the local codes and regulations. Check 

with the local authorities before proceeding.

INSTALLATION NOTES:

Because of many different types of service, feeder and 

distribution equipment, no specific wiring instructions 

can be provided. It is recommended that only copper 

wire be used. In all cases it is essential that while the load 

is connected to the generator, there can be absolutely 

no feedback from the generator to the power line or the 

power line to the generator. When properly installed, the 

normal ATS Control and safety system will eliminate all 

paths and feedback. 

To wire the automatic transfer switch into existing wiring, 

first determine which circuits will be on the emergency load 

circuit. If the entire load is transferred, the transfer switch 

can be wired directly after the watt-hour meter and the 

service entrance, providing the service entrance ampere 

rating is within the transfer switch’s rated capability.

If only specific circuits are to be powered under emergency 

power failure conditions, an additional distribution panel 

designated “emergency distribution panel” must be 

installed. 

All selected emergency circuits are removed from main 

distribution panels and installed in the emergency 

distribution panel. The ATS is then installed between 

the main panel and the emergency distribution panel. 

Suggested circuits: freezer, refrigerator, furnace, emergency 

lights, sump pump, emergency outlet circuits, etc. Total 

running load must not exceed generator rating.

    terminals and cable ends with dialectic grease.

WARNING

The electrolyte is diluted sulfuric acid that is harmful 

to the skin and eyes. It is electrically conductive and 

corrosive. The following precautions must always be 

taken.

  1. Always wear full eye protection and protective 

  clothing.

  2. Where electrolyte contacts skin, wash off 

    immediately with water.

  3. If electrolyte contacts the eyes, flush thoroughly 

    and immediately with water and seek immediate 

  medical 

attention

  4. Spilled electrolyte is to be washed down with an 

    acid neutralizing agent. A common practice is to 

    use a solution of one pound of bicarbonate of 

soda 

    (baking soda) to one gallon of water. The 

    bicarbonate of soda solution is to be added until 

    the evidence of reaction (foaming) has ceased. The 

    resulting liquid is to be flushed with water and the 

  area 

dried.

DANGER: EXPLOSIVE FIRE RISK

  1. Never smoke when near batteries.

  2. Do not cause a flame or spark in the battery area.

  3. Always discharge static electricity from your body 

    before touching batteries by first touching a 

    ground metal surface.

SERVICING BATTERIES

Batteries used on these units may, over time, lose water. 

This is  especially true if you are using a trickle charger 

to maintain your battery. Different types of batteries 

require various types of maintenance. Refer to the battery 

manufacturer for specific recommendations. 

NOTE: Always make sure that a new battery is fully charged 

before installing it on a generator set. Failure to do so 

can cause damage to the engine control module in the 

generator set.

All connections must be clean and tight. Depending on 

your battery type, check the electrolyte in the battery 

periodically to be sure it is above the plates. Never allow the 

battery to remain in a discharged condition.

CONNECTING BATTERY CHARGER & 
BLOCK HEATER

The block heaters on this unit are 3000 watt @120Vac 

heater will need to be hard wired in.

The block heater is thermostatically controlled and when 

connected, will maintain the engine coolant temperature 

between 100 and 120 degrees F.

A three-stage battery charger is provided standard on 

this unit. The charger is an Automatic Battery Charger & 

Maintainer. This charger has three rates of charging. During 

the first mode, known as Bulk charging, the charging
