2.3.3 General Wiring Guidelines
 ControlWave ExpressPAC terminal blocks use compression-type
terminals that accommodate up to #16 AWG wire.
 When making a connection, insert the bare end of the wire (approx
¼” max) into the clamp adjacent to the screw and secure the screw.
 To prevent shorts, ensure that no bare wire is exposed. If using
standard wire, tin the bare end with solder to prevent flattening and
improve conductivity.
 Allow some slack in the wire while making terminal connections.
Slack makes the wires more manageable and helps minimize
mechanical strain on the terminal blocks.
2.3.4 Wiring Power to the CPU/System Controller Board
You can power the ControlWave ExpressPAC by:
 factory-supplied 6V lithium battery
 factory-supplied 12V lithium battery pack (dual lithium batteries)
 factory-supplied 6V, 7AH lead acid battery – used with a 1W, 6V
solar panel system
 factory-supplied 6V, 7AH lead acid battery – used with a 5W, 6V
solar panel system
 factory-supplied 12V, 7AH lead acid battery – used with a 5W, 12V
solar panel system
 user-supplied bulk (nominal +6Vdc, +12Vdc or +24Vdc) power
supply.
