6. Procedure for Cable Connections for Parallel Operation System
(1) Confirm the number of units to be connected in parallel. Identify the input/output power
terminal blocks and control wire connections for parallel operation systems as shown in
the appropriate Figure 5-1 through Figure 5-4.
(2) Connect the external control wire and power wire.
!
Straight through, shielded CAT6 cables with metal shielded RJ-45 plugs
on both sides are to be used for the parallel control signal cables. Use of
any other cables could cause erroneous communication failures.
