SAFETY INSTRUCTIONS
• Use caution to reduce the risk of dropping a metal tool on the battery. It could spark or short
circuit the battery or other electrical parts and could cause an explosion.
• Remove metal items like rings, bracelets and watches when working with batteries. The
batteries can produce a short circuit current high enough to weld a ring or the like to metal
and cause a severe burn.
• If you need to remove a battery, always remove the ground terminal from the battery first.
Make sure that all the accessories are off so that you do not cause a spark.
Charge Controller related
• Please ensure the input voltage fed to the Charge Controller does not exceed 50 VDC to
prevent permanent damage to the Charge Controller. Ensure that the maximum Open
Circuit Voltage Voc of the 12 V nominal Solar Panel / Solar Array is less than 50 V. If two 12 V
nominal Solar Panels are being used in series to make a 24 V nominal Solar Array, make sure
that the maximum Open Circuit Voltage Voc of each of the 12 V Panels is less than 25 V.
• Do not exceed the maximum current rating of 30 A. The Short Circuit Current of the Solar
Array should be less than 30 A.
• Do not exceed a battery voltage of 24V (nominal) . Do not use a battery less than 12V.
• Charge only 12, or 24 volt Lead-Acid batteries when using the standard battery charging
programs or Ni-Cd batteries when DIP Switch number 2~4 is in the ON position.
• DO NOT short circuit the PV array or load while connected to the controller. This will damage
the controller.
• The controller should be protected from direct sunlight. Ensure adequate space for air flow
around the controller's face plate.
• Do not install in a sealed compartment with batteries.
• Never allow the solar array to be connected to the controller with the battery disconnected.
This can be a dangerous condition with high open-circuit solar voltage present at the
terminals.
• Use only copper wire with minimum 75°C insulation rating, and between 10 AWG (5.2 mm
and 14 AWG (2.1 mm
• The Negative system conductor should be properly grounded. Grounding should comply with
local codes.
