Master-Slave Interconnections

For the systems with slave units, three sets of cabling must be interconnected between the PowerLogic™ DVR master and PowerLogic™ DVR slaves. These interconnections are:

DC-link

This connection permits sharing of DC-link to all PowerLogic™ DVR units.
Control signals
Fibre optic

The connections in master-slave units for these interconnections are located on the front side at the bottom-left part of each PowerLogic™ DVR unit, with little difference between master and slave unit.

WARNING
EXPOSED TERMINALS Make sure that the DC-link terminals are correctly connected and that the polarity (+, 0, -) is correct. Failure to follow these instructions can result in death, serious injury, or equipment damage.

The following diagrams show the interconnections between master and slave units of the system.

The three sets of interconnections between master and slaves are provided with the cable length of 4.5 m.

Apply tightening torque of 4 N•m to the screws used for DC-link terminals.

CAUTION
EQUIPMENT DAMAGE Strictly follow the torque tightness and interconnections instructions provided in this section. Failure to follow these instructions can result in equipment damage or malfunctions.
