5.1 Tools
• Insulated tools must be used
• Voltmeter
• Post cleaner and wire brush
• Personal protective equipment
5.2 Battery Location
Locate the batteries close to the inverter in order to minimize the length of the battery cables. Care should be taken to
ensure adequate clearance above the batteries is maintained for access to both battery and inverter connections and
disconnects. A Discover AES Wall-Mount Bracket (p/n 950-0018) is available for use with AES Battery model 42-48-6650.
AES Battery performance and service life will be optimized when they are operated in an ambient temperature of 15°C to
25°C (59°F to 77°F). Care should be taken to ensure that the battery’s temperature is > 0°C (32°F) during charging.
5.3 Securing Battery
• Battery can be strapped in place with non-conductive nylon straps
• Battery may have hold down brackets at the base of the battery
• A Discover AES Wall-Mount Bracket (p/n 950-0018) is available for use with AES Battery model 42-48-6650
5.4 Installation
Battery cables must be sized to the specications required by the inverter charger, and must be installed in accordance with the
standards set by the authority having local jurisdiction. Do not use or install a battery temperature sensor.
• Conrm that battery is set to OFF
• If the battery circuit has a disconnect - open the disconnect to isolate battery
• Cable connection points should always be kept clean
• Broken, frayed, brittle, kinked or cut cables should never be used
• Secure the new battery - be careful not to ground the terminals to any metal mounting, xture, or body part
• Connect battery cables - connect the ground cable last to avoid sparking
• Terminals are button-type, M8 female - recommended torque is 9.0 Nm (6.64 ft-lb)
• If the battery circuit has a disconnect - close disconnect to reconnect the battery
• Set the battery to ON
▲ NOTE!
All cable ends must be connected to battery terminals without
any washers between terminal bushings and cable ends.
Terminal burnout is caused by:
• Discharge currents exceeding allowable limits
• Improper cable installation
• Improper cable sizing
• Improper terminal torque
▲ NOTE!
Without exception, product experiencing terminal burn out
will not be warranted.
