Power Cord Preparation

Before using your power cord:

 Verify that the ground wire is the same gauge or heavier than the power wires.  Do not use aluminum wires for the power supply’s power cord.  If the conductor end (individual) wires are not twisted correctly, the end wires may either

short loop to each other or against an electrode. To avoid this, use D25CE/AZ5CE cable ends.

 Use wires that are 0.75 to 2.5 mm

(18 to 12 AWG) for the power cord, and twist the wire

ends before attaching the terminals.

 The conductor type is solid or stranded wire.  To reduce electromagnetic noise, make the power cord as short as possible.

 Do not solder the wire directly to the power receptacle pin.  The power supply cord must meet the specification shown above. Twist the power

cords together, up to the power plug, for EMC compliance.

 Use field wiring terminal marking for wire type (75 ° C (167 ° F) copper conductors only).

Precautions:

 Connect the power cord to the power connector on the rear module using the power

plug.

 Use a regulated power supply with a Class 2 power supply between the line and the

ground.

 Do not bundle the power supply cord with, or keep close to, main circuit lines (high

voltage, high current), or I/O signal lines.

 Connect a lightning surge absorber to handle power surges.

Excessive stress on the power connection or attempting to install the rear module with the power cables connected may disconnect, or cause damage, to the power connections. This can cause short circuits, fire, or unintended equipment operation.

WARNING

SHORT CIRCUITS, FIRE, OR UNINTENDED EQUIPMENT OPERATION

 Securely attach power cables to the panel or cabinet.  Secure the power plug of the rear module.  Install and fasten the rear module on the installation panel or cabinet prior to

connecting power supply and communication lines.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Power Supply Connections

For maintenance purpose, use the following connection diagram to set up your power supply connections. However, when terminals A2 and B2 (signal name: Q1, Q0) are wired to external I/O, use the same power source for external I/O and the LT:

When wiring terminals A2 and B2 (signal name: Q1, Q0) to external I/O:

NOTE:

 When connector A2 and B2 (Signal Name: Q1, Q0) are wired to external I/O, turn on the

LT before turning on the external device. Otherwise the wrong signal for Pulse Output, PWM Output and High-speed Counter (Synchronize Output) will be output. When transferring a program that turns off or resets the LT, first turn off the external device. When using a system with multiple power supplies, please note there is also a power supply in the external device.

English

 Ground the surge absorber separately from the rear module.  Select a surge absorber that has a maximum circuit voltage greater than the peak

voltage of the power supply.

Grounding the System

To minimize the effects of electromagnetic interference, cables carrying the fast I/O, analog I/O, and Serial communication signals must be shielded.

IMPROPER GROUNDING CAN CAUSE UNINTENDED EQUIPMENT OPERATION

 Use cables with insulated shielded jackets for analog I/O, fast I/O and communication

 Ground shielded cables for analog I/O, fast I/O and communication signals at a single

 Always comply with local wiring requirements regarding grounding of cable shields.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

signals.

point

WARNING

To avoid damage to the shielded cable when there is a short circuit in the power line, set

up a multi-point frame ground (FG) each with the same electric potential.

The use of shielded cables requires compliance with the following wiring rules:

 When there is no protective earth ground, you can use metal conduit or cable duct

shield as a part of the protective earth ground. The functional ground (FE) shield must attenuate electromagnetic interference and must be shielded the length of the cable. If the purpose is for both functional and protective grounding, as is often the case for communication cables, the cable must have continuous shielding.

 Wherever possible, keep cables carrying one type of signal separate from the cables

carrying other types of signals or power.

Protective Earth Ground on the Backplane

For protective grounding, connect braided copper cable (that can withstand the maximum voltage/current allowed by the system) to the conductive backplane.

Page 39

LT-4201TM/4301TM Installation Guide

Functional Ground on the DIN Rail

The DIN rail for your LT system is common with the functional ground plane and must be mounted on a conductive backplane.

WARNING

UNINTENDED EQUIPMENT OPERATION

When connecting DIN rails, connect the DIN rails to functional ground (FE).

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Shielded Cable Connections

Cables carrying the fast I/O, analog I/O, and Serial communication signals must be shielded. The shielding must be securely connected to ground. The fast I/O and analog I/O shields may be connected either to the functional ground (FE) or to the protective earth ground (PE) of your LT.

WARNING

ACCIDENTAL DISCONNECTION FROM PROTECTIVE GROUND (PE)

 Do not use the grounding bar to provide a protective earth ground (PE).  Use the grounding bar only to provide a functional ground (FE).

Failure to follow these instructions can result in death, serious injury, or equipment damage.

English

DANGER

HAZARD OF ELECTRIC SHOCK

Make sure that CANopen and Modbus cables are securely connected to the protective earth ground (PE).

Failure to follow these instructions will result in death or serious injury.

Step Description

1 Strip the shielding for a length of

15 mm (0.59 in.).

2 Use the metal grounding clamp(2) to

attach the cable to the backplane plate

(1) as close as possible to the LT.

NOTE: The shielding must be clamped securely to the conductive backplane to ensure

good contact.

Exclusive Grounding

Connect the frame ground (FG) terminal on the power plug to an exclusive ground. When supplying power to the LT unit, be sure to separate the input, output and power lines, as shown:

Page 41

LT-4201TM/4301TM Installation Guide

Common Grounding

If exclusive grounding is not possible, use a common grounding point. Use grounding resistance of 10 Ω or less, wire thickness of 2.6 mm or more, or your country’s applicable standard for the grounding point.

Precautions:

 Do not use common grounding, since it can lead to accidents and machine breakdown.  If the equipment does not function properly when grounded, disconnect the ground wire

from the FG terminal.

If exclusive grounding is not possible, use a common connection point.

English

Grounding Procedure

Step Action

1 Check that the grounding resistance is less than 100 Ω.

(Grounding resistance of 100 Ω or less, wire thickness of 1.6 mm or more, or your country’s applicable standard.)

2 Create the connection point as close to the unit as possible, and make the wire as short

as possible. When using a long grounding wire, replace the thin wire with a thicker wire, and place it in a duct.

NOTE: FG and SG terminals are internally connected in the LT. When connecting an external device to the LT using the SG terminal, be sure to check that no short-circuit loop is created when you setup the system.
