2. Installation Instructions
2.1 General Installation Notes
 Please read the entire installation instructions to get familiar with the installation steps before
installation.
 Be very careful when installing the batteries, especially flooded lead-acid battery. Please wear
eye protection, and have fresh water available to wash and clean if any contact with battery acid.
 Keep the battery away from any metal objects, which may cause short circuit of the battery.
 Explosive acid battery gases may come out from the battery during charging, so make sure
ventilation condition is good.
 Ventilation is highly recommended if mounted in an enclosure. Never install the inverter/charger
in a sealed enclosure with flooded batteries! Battery fumes from vented batteries will corrode and
destroy the inverter/charger circuits.
 Lead-acid battery is only recommended, other kinds please refer to the battery manufacturer.
 Loose connections and corroded wires may result in high heat that can melt wire insulation, burn
surrounding materials, or even cause fire. Ensure tight connections and use cable clamps to
secure cables and prevent them from swaying in motion.
 Select the system cables according to 5A/mm
2
or less current density in accordance with Article
690 of the National Electrical Code, NFPA 70.
 For outdoor installation, keep out of the direct sunshine and rain infiltration.
 High voltage still exists inside the inverter/charger after switching off the power switch, do not
turn on or touch the internal units, conduct the associated operation only after discharging the
electric capacity.
 Do not place the inverter/charger in a damp, oily, inflammable and explosive or a severe
environment with a large amount of dust accumulation.
 Prohibit reverse connection at DC input end otherwise it may damage the equipment or
unpredictable danger will occur.
 The utility input and AC output are of high voltage, do not touch the wire connetion.
