2. Connect the positive terminals (labeled "POS") of each unit
together at a common positive load point using the optional ICT-
PAR parallel straps (shown above). See figure 4.
3. Connect the negative terminals (labeled "NEG") of each unit
together at a common negative load point using the other ICT-
PAR parallel strap (as shown above).
4. Using a RJ11 four-wire straight-though cable (Optional accessory
part no. ICT-JMP), connect the SHARE "A" terminal on the first

not configured correctly for parallel operation, a "Parallel
Configuration Error" warning will be displayed on the Control
Panel display.
