•Connecting to the Power Source
FormodelsDLC-xE2-Kor-L, connectanACsupplysourceacrossthe
terminal U and V.
For models DLC-xE2-S or -R, connect a DC supply source across the
terminal U(+) and V(–).
•Twisted-Pair Cable
1) Use a cable at the minimum of 0.9 mm diameter.
2) Connect between the LINE terminal (+) and (+), (–) and (–) of the
corresponding units.
3) Installtransmissioncables inageneral instrumentationcablepit or
rack, separate from those for power supply cables, in order to
prevent noise interference.
•Fiber Optics
1) Connect a fiber link connector to Fiber Link terminal.
2) Observe an enough radius when bending fiber optics cables.
3) Follow installation instructions by the cable manufacturer.
•DIN Terminals
Power supply, twisted-pair cable transmission line, RUN output are
connected at the DIN terminal block.
The terminal block is composed of the base connector and the
removable plug. Clamp the cable with the screw in the clamping unit.
Solid cables must be with a pin terminal. Stranded cables must be of
1.4mmdia.atthemaximum. DONOTsolderwiresinstrandedcables.
•Wiring Procedure for Terminal Block
Terminating Resistor
A transmission line via twisted-pair cables needs to have terminating
resistorsinordertopreventthe transmissionwaveform fromreflecting
at the ends of the line.
Each DLC unit incorporates a terminating resistor which is connected
with a jumper across the terminating resistor terminals. When the
system is composed of three or more units, remove the jumper from
those which are not at the both ends of transmission line in order to
disconnect the terminating resistors.

Station Address
Station number (Station Address = SA) is selectable with the front
accessed DIP rotary switches (SA1 and SA2), from 00H to FFH.
Assign an even number to one unit and assign the consecutive one to
the paired unit.
For example, assign “02” and “03,” or “1A” and “1B.”
More than two units cannot be paired.
Checking
1) Check that all cables are correctly wired according to the connec-
tiondiagram. Check polarityof thetransmission cablesand power
supply cables.
2) Check Station Address.
3) Terminating resistor (required only for units at the both ends of
transmission line)
4) Check the I/O signals.
Lightning Surge Protection
In order to prevent lightning surges entering through power supply line
and signal line, proper surge protection will be required. Specify
our M-RESTER Series Lightning Surge Protectors.
