Installation instructions

6.1General installation notes

• Please read the manual carefully to get familiar with the installation steps before installation.
• Be very careful when installing the batteries, especially flooded lead-acid batteries. Please wear eye protection, and have fresh water available to rinse if any contact with battery acid.
• Keep the battery away from any metal objects, which may cause a short circuit of the battery.
• Loose connections and corroded wires may result in high heat that can melt wire insulation, burn surrounding materials, or even cause a fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in motion.
• Please follow the parameter list to connect the DC input, even though the inverter has a high range of DC input voltages. Too high or too low may cause the inverter to stop working, even damage the inverter (Surge voltage less than 20V for 12V system, 40V for 24V system, 80V for 48V system)
• Select the system connection cables according to the current density no higher than 3.5A/mm 2 .(In accordance with the National Electrical Code Article 690, NFPA70).
• For outdoor installation, keep out of the direct sunshine and rain infiltration.
• High voltage still exists inside the inverter after turning off the switch, do not open or touch the internal devices, wait ten minutes before conducting related operations.
• Please do not install the inverter in humid, greasy, flammable, explosive, dust accumulative, or other severe environments.
• AC output is a high voltage, and please do not touch the wiring connection.
• When the fan is working, and please do not touch it to avoid injury.

IMPORTANT: The inverter shall be installed in a place with sufficient airflow through the dissipation pad of the inverter and a minimum clearance of 150mm from the upper and lower edges of the inverter to ensure natural thermal convection.
CAUTION: The inverter shall be cooling through case if installed in a closed box.
IP1500-12-Plus/IP2000-**-Plus

Step3：Wiring
WARNING： The AC equipment shall be determined by the continuous output power of the inverter, but the surge power must be lower than the instantaneous surge power of the inverter.
CAUTION: The switch of the inverter off before wiring.
CAUTION: DO NOT close the circuit breaker or fuse and make sure that the leads of the “+” and “-” poles are correctly connected while wiring the inverter.
CAUTION: A fuse whose current is 2 to 2.5 times the rated current of the inverter, it must be installed on the battery side with a distance from the battery not greater than 150mm.

Maintenance

The following inspections and maintenance tasks are recommended at least two times per year for the best performance.

• Make sure no block on airflow around the inverter. Clear up any dirt and fragments on the radiator.
• Check all the naked wires to make sure insulation does not damage for serious solarization—frictional wear, dryness, insects or rats, etc. Repair or replace some wires if necessary.
• Check and confirm that indicator and display is consistent with required. Pay attention to any troubleshooting or error indication. Take corrective action if necessary.
• Confirm that all the terminals have no corrosion, insulation damage, high temperature or burnt/discolored sign, tighten terminal screws to the suggested torque.
• Check for dirt, nesting insects, and corrosion. If so, clear up in time.
• Check and confirm that the lightning arrester is in good condition.
  Replace a new one in time to avoid damaging the inverter/charger and even other equipment.

WARNING：Risk of electric shock!
Risk of electric shock! Before the above operations, make sure that all the power turns off, and the electricity in the capacitances is completely discharged, then follow the corresponding inspections and operations.
