Units
Connecting Round
Cable I/II
The DCN4-TB4 Open Type Connector is used to convert the communications
connector on the Slave Unit or Repeater Unit to a terminal block (M3) for con-
necting the cable wires.
Installation Method
1,2,3... 1. Attach the Open Type Connector to the communications connector of the
Slave Unit or Repeater Unit.
Orient the Open Type Connector so that the side with the open terminals
is facing to the left and press in the Open Type Connector until it clicks into
place.
Note To remove the Open Type Connector once it has been attached,
firmly press in on the latches on both sides and pull out the Open
Type Connector.
2. Open the terminal cover of the Open Type Connector and connect the ca-
ble wires to BDH (communications data high) and BDL (communications
data low) in the terminal block. For round cable II, connect the cable wires
to BS+ (communications power supply plus) and BS- (communications
power supply minus).
Note Before connecting the cable wires to the terminal block, first attach the M3
crimp terminals shown below to the wires.
