MotorGuide BATTERY CHARGERS - Manual (Page 4)

h) 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 current high enough to
weld a ring or any other metal, causing serious burns.
Not intended to supply low voltage electrical systems other than in a marine application. Do not
use your marine 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 the grounded
negative terminal from the battery first. Make sure all accessories in the boat are off,
as to not cause an arc. 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.
For flooded batteries add distilled water in each cell until electrolyte reaches levels specified
by the battery manufacturer. This helps purge excessive gases from cells. Do not overfill. For
batteries without caps, carefully follow manufacturer's recharging instructions.
Study all manufacturer’s specific precautions, such as removing or not removing cell caps
while charging, in addition to battery type for proper rate of charge.
Extension cords should be industrial grade / heavy duty UL approved and grounded. Check
extension cord before use for damage, bent prongs, and cuts. Replace if damaged. Always make
your extension cord connection on the charger side first. After connecting the extension cord
to the charger proceed to plug the extension cord to a nearby 120 VAC GFCI protected (Ground
Fault Circuit Interrupt) outlet.
Always remove the extension cord from the 120 VAC outlet first when charging is
completed followed by unplugging the charger, completely disconnecting
IMPORTANT NOTICE: FCC CLASS A PART 15 NOTIFICATION
Your On-Board Marine Battery Charger has been designed and tested to comply with FCC Class A
part 15. These regulations are to provide adequate protection against harmful interference while
operated in a commercial application. If in a residential setting, you are encountering interference
with TV and radio reception, simply remove AC power from the MotorGuide unit to confirm if your
battery charger is causing interference. End user can explore the following to minimize interference:
1) Chose a different AC circuit to power your On-Board Marine Battery Charger.
2) Make sure your outlet is properly grounded.
3) Re-position receiving antenna.
4) Purchase a separate AC line filter.
5) Relocate charger so that it is at the furthest point from home receiving equipment,TV, radio, etc.
