3 Installation
3.1 Location
Unit is designed for installation in a protected environment. Factors to be considered in selecting a location
include ventilation, temperature, humidity, and accessibility. Install the unit in a clean, dry location with an
unrestricted air flow and sufficient space for rear and front access. Unit will provide its full capability in ambient
temperatures from -5°C to 50°C. Higher ambient temperatures will lead to a shorter life. Gasses emanating from
the battery can be corrosive and highly flammable, so isolate the unit from the battery as much as possible.
3.2 Frame Assembly
3.2.1 Install Controller/Interface/STS Chassis
1. The controller/interface/STS chassis is pre-installed with 19-inch rack brackets. For
23-inch rack mounting, please exchange with the proper mounting brackets.
2. Put the controller/interface/STS chassis to the equipment rack horizontally above
inverter shelf, and align holes of mounting brackets and rack. Secure the chassis in
position with four cross pan type nickel screws as shown:

3. All input and output connections are made through the knock outs located in the top
of rear cover and both side panels. The rear cover accompanies the
controller/interface/STS chassis originally. The rear cover shall be removed to start
wiring.
4. Screw off the rear cover with a cross-head screw driver. Cut the rear cover with a
diagonal cutter on the indication line. Remove the rear cover and you will be able to
see the whole appearance of controller/interface/STS chassis PCB and connectors.
