Safety Instructions

General Safety Instructions
Before connecting your batteries or AC power, read all instructions and cautionary
markings on the battery charger and batteries.
CAUTION - To reduce the risk of injury, charge only lead acid type rechargeable batteries
(lead acid, sealed lead acid, GEL cell and AGM (Absorbed Glass Mat). Other types of
batteries may burst, causing personal injury. The ProTech-4 series battery charger is
factory set for lead acid (flooded) and AGM (Absorbed Glass Mat) batteries. Check the
position of the battery type selector switch before installation.
Use of attachments not recommended or sold by Professional Mariner, LLC may result
in a risk of fire, electrical shock or personal injury.
Do not operate the charger if it has received a sharp blow, direct hit of force, dropped or
otherwise damaged in any way.
Do not disassemble the charger except for replacement of fuse. Call the factory directly
when service or repair is required.
Incorrect assembly may result in risk of electrical shock or fire.
To reduce the risk of electrical shock, remove 120 Volt or 240 Volt AC power from the
charger as well as 12, 24, 32, 36 Volt DC prior to any maintenance or cleaning.
WARNING
AVOID SERIOUS INJURY OR DEATH FROM FIRE, EXPLOSION OR ELECTRICAL SHOCK.
• Make connection in an open atmosphere free of explosive fumes.
• Make connection in a secure manner that will avoid contact with water.
WARNING: RISK OF EXPLOSIVE GASES
WORKING IN THE VICINITY OF A LEAD ACID BATTERY IS DANGEROUS. BATTERIES
GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS
REASON IT IS OF EXTREME IMPORTANCE THAT EACH TIME BEFORE USING YOUR
CHARGER YOU FOLLOW THE SAFETY INSTRUCTIONS PROVIDED IN THIS MANUAL.
To reduce risk of battery explosion, follow these instructions and those published by the
battery manufacturer, and of any equipment you intend to use in the vicinity of a battery.
Review all cautionary markings and labels.
Personal Safety Precautions
Someone should be within the range of your voice or close enough to come to your aid
when working near a lead acid battery.
Have plenty of soap and water nearby in case battery acid comes in contact with skin,
clothes or eyes.
Safety Instructions
Personal Safety Precautions Continued
Never smoke or allow a spark or flame in the vicinity of a battery or engine.
Wear complete eye protection and skin protection. Avoid touching eyes while working
with a battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters the eye flood it with running cold water for at least 10 minutes and get medical
attention immediately
Be extra cautious to reduce risk of dropping a metal tool onto a battery. It may spark
or short-circuit the battery which could cause an explosion.
Remove all personal metal items such as rings, bracelets, necklaces, watches, and
jewelry when working near a battery. A battery can produce a short circuit high enough
to weld a ring or any metal, causing serious burns.
The ProTech-4 battery charger is not intended to supply low voltage electrical systems
other than in a marine application. Do not use the battery charger to charge dry cell
batteries that are commonly used with home appliances. These batteries may burst
and cause injury to persons and property.

Never charge a frozen battery.
Safety Precautions Prior to Charging Batteries
If necessary to remove a battery from a boat to charge, always remove grounded
terminal from the battery first. Make sure all accessories in the boat are off, as to
not cause an arc (sparking of the connection).
Be sure the area around the charger and batteries is well ventilated while the batteries
are being charged. Gases can be forcefully blown away using a piece of cardboard
or other nonmetallic material as a fan.
Clean battery terminals with full eye protection to prevent corrosive material from
coming in contact with eyes.
Add distilled water (not tap or bottled water that contains minerals) in each cell
until electrolyte reaches levels specified by the battery manufacturer. Do not overfill.
For batteries without caps, carefully follow manufacturers’ recharging instructions.
Study all manufacturers’ specific precautions before charging, in addition to rates
of charge.
ProTech4 Overview / Installation Guidelines
3
General Overview
The ProTech-4 battery charger will operate from 90 to 270 VAC, 45 to 440 Hz single
phase. The charger is designed specifically for the marine environment, with an
anodized aluminum case for effective heat dissipation and corrosion resistance.
The charger should be permanently mounted in your boat and wired directly to
your batteries. Three isolated positive outputs are incorporated to sense and
charge three separate heavy-duty batteries or battery banks as needed.
The ProTech-4 battery charger is reverse polarity protected and is equipped with
two cooling fans for optimum performance. The ProTech-4 battery charger’s fans
will not run at all times. The fan will turn on as needed for cooling.
Installation Guidelines
The charger should be securely fastened with stainless steel screws or throughbolts with lock nuts. Vertical mounting on a bulkhead is preferred, but mounting
in any position that allows air to circulate with six inches of clearance space on
all sides is required. The ProTech-4 battery charger operates at ambient
temperatures up to 50 degrees C/140 degrees F.
The Protech-4 has a fuse block on the negative side (30 amp and larger) to protect
the charger from reverse polarity. 10, 15 and 20 amp chargers have a reverse
polarity fuse located inside the unit.
The 30 amp and larger chargers in the ProTech-4 family are equipped with an
AC input selector switch to change the Voltage from 120 Volt to 240 Volt. Smaller
chargers with less than 30 amp output do this automatically. (Voltage switch
