IMPORTANT SAFETY INSTRUCTIONS
1. READ AND SAVE THESE INSTRUCTIONS
This manual contains important safety and operating instructions for the BatteryLink® Charger.
2. 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 the utmost
importance that each time before using your charger, you read and follow the instructions provided exactly.
3. TO REDUCE RISK OF BATTERY EXPLOSION, follow these instructions and those marked on the battery.
4. WARNING
AVOID SERIOUS INJURY OR DEATH FROM FIRE, EXPLOSION, OR ELECTRICAL SHOCK.
The BatteryLink ® Charger is marked as "ignition protected" for operation in a small craft gasoline engine space.
Connection or disconnection of any electrical cables may cause sparks, which could ignite
HOWEVER:
flammable gasses and cause explosion.
a. Never connect or disconnect electrical cables when explosive gasses may be present.
b. Always disconnect AC power sources before connecting or disconnecting the charger AC cord.
c. Connect AC plug only to a GFCI protected (Ground Fault Circuit Interrupt) outlet, and make AC connection in
a secure manner that will avoid contact with water. If no GFCI protected outlet is available on board, a
Marinco ® 30A to 15A adapter with GFCI protection (Marinco# 199128) can be used for safe connection
to the dock/marina.
5. THE BATTERYLINK® CHARGER IS DESIGNED FOR USE ONLY in a permanent installation aboard a vessel or
in a vehicle. It is not intended for use as a portable charger.
6. USE OF AN ATTACHMENT NOT RECOMMENDED OR SOLD BY BLUE SEA SYSTEMS may result in a risk of
fire, electric shock, or injury to persons.
7. TO REDUCE RISK OF DAMAGE TO ELECTRIC PLUG AND CORD, pull by plug rather than cord when
disconnecting charger.
8. AN EXTENSION CORD SHOULD NOT BE USED UNLESS ABSOLUTELY NECESSARY. Use of an improper
extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
a. That extension cord is industrial grade / heavy duty, UL approved for outdoor use, and grounded.
b. That pins on plug of extension cord are the same number, size, and shape as those of plug on charger.
c. That extension cord is properly wired and in good electrical condition, free of any damage, bent pins, or
cuts to jacket or insulation.
d. That you always make your extension cord connection on the charger side first, and disconnect the
charger side last.
e. That wire size is large enough for AC input ampere rating of charger. Refer to the chart below to determine
the minimum wire size for extension cord.

9. DO NOT OPERATE CHARGER WITH DAMAGED CORD OR PLUG. Contact Blue Sea Systems for servicing.
10. DO NOT OPERATE CHARGER IF IT HAS RECEIVED A SHARP BLOW, been dropped, or otherwise damaged
in any way; contact Blue Sea Systems for servicing.
11. DO NOT DISASSEMBLE CHARGER; contact Blue Sea Systems for servicing. Incorrect reassembly may result
in a risk of electric shock or fire.
12. TO REDUCE RISK OF ELECTRIC SHOCK, unplug charger from outlet before attempting any maintenance
or cleaning. Turning off controls will not reduce this risk.
13. PERSONAL PRECAUTIONS
a. Someone should be within range of your voice or close enough to come to your aid when working near a
lead-acid battery.
b. Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
c. Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.
d. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
