Important Safety Instructions
WARNING!
The temperature of the batteries located in the PWE-SG may differ from those located in the •
legacy enclosure containing the power supply. The design of the PWE-SG minimizes this
difference when the two enclosures are subjected to the same ambient. Always place the battery
temperature sensor, ocntrolling the battery temperature charge compensation, on the hottest
battery. This is typically the center battery located directly below the power supply in the legacy
enclosure.
Lead-acid batteries generate explosive gases. To prevent arcing or burning near batteries, do
•
not disconnect DC charging cord from batteries when the charger is operating. Switch the AC
breaker and the DC breaker to the "OFF" position before disconnecting the DC output cord from
the batteries.
Always shield eyes when working near batteries. Do not put wrenches or other metal objects
•
across the battery terminal or battery top. Arcing or explosion of the battery can result.
Batteries produce hydrogen gas, which explodes if ignited. Never smoke, use an open flame,
•
or create sparks near the battery. Ventilate the area when the battery is charging in an enclosed
place.
Lead-acid batteries contain sulfuric acid, which may cause burns. Do not get acid in eyes, on
•
skin, or clothing. If contact with the eyes occur, flush immediately with clean water for 15 minutes
and seek medical attention.
