4. BATTERY INSTALLATION
4.1. Battery Connections
To maximize the performance and to ensure safe operation of your battery,
use the appropriate cable size and tighten connections using the proper
torque value. Refer to the data sheet for your particular battery's torque
value. It is recommended to use a washer. Place the washer between the
cable lug and nut, not between the cable lug and battery terminal surface.
4.2. Cable Size
Choose the appropriate cable
size based on the expected
load of your system. See the
table below – ENEC 310.15 (B)
(16) – Allowable Ampacities for
copper cables rated at 167°F
(75°C) operating at an ambient
temperature of 86°F (30°C).
4.3. Torque Values
Terminal connections should
adhere to the appropriate
torque values for the specified terminal type to provide optimum electrical
conductivity. Refer to the data sheet for your particular battery's torque value.
Over- or under- tightening the connections can result in terminal breakage,
over-heating and/or terminal melting. Use a rubber handled or insulated
wrench when making terminal connections to avoid an external short circuit.
4.4. Terminal Protection
Battery terminals may be covered with a plastic cap to prevent an
external short circuit. Terminals must be covered with a protective cap or
non-conductive tape prior to battery disposal to a lithium recycler.
