INSTALLATION OVERVIEW

Installation Preparation
Prior to installation ensure that all Load Equipment to be connected to the battery system is in good condition and free from defects. Double check all cabling for exposed wiring, loss of integrity, or poor insulation. Ensure all battery and power systems are reliably grounded. Please double check that all power systems are in the OFF state.

1. Mounting Lug Installation
2. Battery Rack Installation

3| Electrical Installation|

1. Ground Battery
2. Battery Power Cable Installation
3. Connection to Equipment
4. Communication Cable Installation

4| Commissioning the Battery| Power system on – first commission

Ensure that Inverter and Solar Equipment is powered off, as well as Battery Bank is powered off.
Installation of Mounting Lugs – Equipment will be fixed to rack or mounting bracket by the chassis mounting lugs, before the installation of equipment, fix the mounting lugs on both sides of the battery box, ensure that the installation is strong and stable.
Battery Rack Installation – Module mounted in the rack 19 inch ( or cabinet ), when installed use portable handles to arrange in parallel on the frame ( or cabinet ) use the supporting plates within the rack ( or cabinet ), ensure the mounting lugs and frame ( or cabinet ) edge securing with screw into the rack to the mounting holes to ensure that the battery pack mounted solid in the rack.
Ground Battery – use a Grounding cable. The grounding cable ends with a screw. You will fit the chassis rear grounding hole, the other end is connected to the frame ( or cabinet ) grounding copper bar, always double- check to ensure a stable connection.
Power Cable Installation. When using a single battery, battery terminals directly connected to the device or switch power supply terminal, if there are multiple batteries in parallel when in use, please connect all batteries to the copper  bus-bar with the power cables.
Connection to Equipment – Connect the copper bus-bar to the charger/load system with power cable to your equipment. ENSURE NOT TO REVERSE POLARIZE!
Communication Cable Installation. When the battery is used in a single, please skip this step. When a plurality of batteries are used in parallel please name each battery based on their dip switches. ( ensure no duplicate address codes are used ), and then connect the communication interface of RS485 one by one. Connect the first or last battery module RS485 interface to the inverter or PC monitor.
After all previous steps have been completed, turn ON each battery module (including their respective output circuit breaker to ON), one at a time, pausing between each to allow the batteries to stabilize. Continue until all battery modules are ON and terminal voltage is detected on the bus bar. If any battery module does not start, or the front panel “ALM” (alarm) lights, or the output circuit breaker goes OFF, immediately turn OFF all battery modules and disconnect the offending battery module from the rack bus bar and remove it from the rack for further inspection. Once all connected battery modules are deemed functioning properly, then turn ON or enable power sources and loads, one at a time, while monitoring the battery modules, sources, and loads for any anomalies. If any battery module front panel “ALM” (alarm) lights, or any circuit breaker trips, or fuses blow, or arcing, or smoke, immediately turn OFF all battery modules, sources, and loads and correct the fault before proceeding.
Caution: If you have any questions about the installation, stop and contact technical support to avoid damage or accidents.
