Fig. 6-49 Parallel connection of two slave units
Table 6-13 shows the relationship between the number of slave units and the capacity.

• When carrying out parallel operation, be sure to use the load input termi-
nal on the rear panel. Do not connect other equipment to the load input ter-
minal on the front panel.
• Improper connection of the J1 and J2 connectors can damage the PLZ-4W.
• Use the shortest load wire and flat cable possible for the connection. Use a
load wire of sufficient thickness by taking into account the current being used.
It is recommended to use the bus bar instead of wiring the cable.
• Separate the load cable from the flat cable as much as possible to prevent unstable
operation.
