Someone should be within range of your voice or close enough to come to your
aid when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, eyes, or other surfaces.
Wear complete eye protection and clothing protection. Avoid touching eyes while
working near battery.
If battery acid contacts skin or clothing, wash immediately with soap and water.
If acid enters eye, immediately flood eye with running cold water for at least 10
minutes and seek medical attention promptly.
NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
Be extra cautious to reduce risk of dropping a metal tool onto the battery, which
might cause a spark or short-circuit the battery or another electrical part, possibly
resulting in an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches
when working with a lead-acid battery. A lead-acid battery can produce a short-
circuit current high enough to weld a ring or the like to metal, causing a severe
burn.
Use the ProXtra for charging a LEAD-ACID (lead acid, sealed lead acid, gel cell,
and AGM) battery only. Do not use this system for charging dry-cell batteries
that are commonly used with home appliances. These batteries may burst,
causing personal injury and damage to property.
NEVER charge a frozen battery.
PRODUCT SUMMARY
General Operation
Use the following guidelines in this manual to install your PCS ProXtra system.
Assure that the area around your batteries is properly ventilated.
During normal operation the ProXtra system monitors the starting battery voltage
and will activate once the starting battery voltage rises above a predetermined
voltage. Once this point is reached, charging current from the boat motor
charging system will continue to flow to the additional batteries attached to the
ProXtra system. When the starting battery voltage drops below a predetermined
voltage, the ProXtra system is deactivated and returns to a standby state. Light
Emitting Diodes (LEDs) on the ProXtra case indicate the status of the unit.
