• The power connector (plug) is CA5-
DCCNM-01 made by Digital Electronics
Corporation or MSTB2,5/3-ST-5,08 made
by Phoenix Contact.
When connecting the Power Cord, use the
following items when performing wiring.
(Items are made by Phoenix Contact.)
„ Connecting the LT Power Cord
(1) Confirm that the LT unit’s Power Cord is
unplugged from the power supply.
(2) Strip the power cord, twist the
conductor’s wire ends, insert them into
the pin terminal and crimp the terminal.
Attach the terminal to the power
connector (plug).
• Use a flat-blade screwdriver (Size 0.6 x
3.5) to tighten the terminal screws.
The torque required to tighten these
screws is 0.5 to 0.6 N
•m [5-7Lb•In.].
• Do not solder the cable connection.
Doing so may damage the unit due to
abnormal heat or cause a fire.
(3) Attach the Power connector (Plug) to the
Power Connector.
2. Power Supply Cautions
• Input and Output signal lines must be sepa-
rated from the power control cables for
operational circuits.
• To improve the noise resistance, be sure to
twist the ends of the power cord wires
before connecting them to the Power con-
nector (Plug).
• The LT unit’s power supply cord should
not be bundled with or kept close to main
circuit lines (high voltage, high current), or
input/output signal lines.
• To reduce noise, make the power cord as
short as possible.
• If the supplied voltage exceeds the LT
unit’s range, connect a voltage transformer.
• Between the line and the ground, be sure to
use a low noise power supply. If there is an
excess amount of noise, connect a noise
reducing transformer.
• The temperature rating of field installed
conductors: 75
°C only.
• Use voltage and noise reducing trans-
formers with capacities exceeding
Power Consumption value.
• Must be used with a Class 2 Power Supply.
(24VDC)
• Connect a surge absorber to handle power
surges.
• Be sure to ground the surge absorber
(E1) separately from the LT unit (E2).
Select a surge absorber that has a
maximum circuit voltage greater than
that of the peak voltage of the power
supply.
