Do not install in a location having any of the following characteristics:

• High or low temperatures or high or low humidity outside of the specification range

• Sulfide gas or other corrosive gases

• Dust or oily smoke

• Direct sunlight, wind or rain

• Mechanical vibration or shock outside of the specification range

• Nearby high-voltage lines, welding machines or other sources of electrical noise

• Within 15 meters of a device with high-voltage ignition, such as a boiler

• Strong magnetic fields

• Flammable liquid or gas

■ ■

Module connection

Connect this module to other modules using the connectors on the left and right sides of the base.

Connect modules together before installing them on the DIN rail. Connecting the modules connects the power and communication of each module, reducing the amount of wiring that is required. With RS-485 communication, the module on the right side can be disconnected using the RS-485 cutoff switch on the base.

■ ■

Mounting procedure

Use this unit after securing it to a DIN rail.

After mounting the DIN rail, pull open the locking tab an adequate amount and then attach the base to the rail. Next, push in the DIN rail locking tab upwards until it clicks into place.

Handling Precautions

• Mount the unit so that it is vertical with the DIN rail

• Link this unit before installing it on the DIN rail.

■ ■

Attaching the main unit to the base

Handling Precautions

• Use the base and main unit from the same package together as a pair.

• First attach the hook at the bottom of the main unit to the base. Not doing so might cause damage.

(1) Attach the hook at the bottom of the main unit to the base.

(2) Insert the upper part of the main unit until the lever clicks into place.

Changing Batteries

■ ■

Changing batteries

The backup battery can be replaced while in an energized state or when the power is OFF.

Handling Precautions

• To replace the battery while the power is OFF, make sure the device was energized for at least 60 minutes before power is turned OFF, and perform the replacement within 10 minutes. Otherwise, backup data may be lost on occasion.

• If replacing the battery while in an energized state, it will take up to 3 minutes for the low battery indicator to turn off.

• When returning the battery folder to the device, firmly press down the removal lever until it clicks into place.

• How to replace when turning the power OFF

(1) Use the SLP-NX to backup device data on a computer.

(2) Make sure the device was energized for at least 60 minutes, then turn the power OFF.

(3) Remove the device from the base, remove the battery cover from the bottom of the device, and take out the battery.

(4) Fit the replacement battery inside of the battery holder, attach it to the connecter, and hang it on the cable hanger.

(5) Return each battery folder to the device, and reconnect the device to the base.

• How to replace while in an energized state

(1) Remove the battery holder from the bottom of the device, and remove it from the connecter.

(2) Take the battery out of the battery holder.

(3) Fit the replacement battery inside of the battery holder, attach it to the connecter, and hang it on the cable hanger.

(4) Return each battery folder to the device.

Terminal Wiring Diagram

■ ■

Wiring precautions

• Make sure that the wiring follows regulations for indoor wiring and technical standards for electrical equipment.

• Do not mount wiring outdoors. Doing so might cause electric shock.

• When connecting wires to the power terminals, use crimp terminals with insulating sleeves.

• Before wiring the unit, verify the device’s model No. and terminal Nos. written on the wiring diagram on the side of the main body.

• Use M3 crimp-type terminal lugs for wiring to a screwtype terminal block.

• Pay special attention so that no crimp type terminal lugs make contact with adjacent terminals.

• Leave a distance of at least 60 cm between I/O lead wires and communications lead wires or power lead wires. Also, do not pass these lead wires through the same conduit or wiring duct.

• When connecting in parallel to another device, check the requirements of the other device carefully before performing instrumentation.

• To ensure stability, the unit is designed so that after the power is turned ON, there is no output for about 10 seconds.

• When the wiring is completed, check that there are no wiring mistakes before turning the power ON.
