Chapter 2 : Installation
2-1 : Precautions
CAUTION
Once the model KUX60/70 converter is installed, do not use it as foot-hold or any
other improper purpose. Doing so may damage the equipment and could result in
personal injury.
• When installing the converter, position and secure the gasket in order to avoid
any leakage from where the converter is connected to the pneumatic signal line. If
gasket protrudes out, output errors may results.
• Do not use the converter under any other operating conditions than those
specified in the product specifications. Using this product under incorrect
operating conditions may result in damage to the product or leakage that could
lead to a major accident.
• Wiring work in a hazardous area should be performed carefully by following the
procedures specified in explosion-protection guidelines.
2-2 : Installation to pipe
Sealing tape
Figure 2-1 Installing on to pipe
• Securely wrap sealing tape around the joint of the connecting pipe to prevent
leakage. Using a wrench, securely tighten the pneumatic line port of the converter
to the connecting pipe. When doing so, use a wrench to hold the chamfering
part. Do not tighten by holding the housing of the product as this may damage
the converter. Avoid holding the housing when tightening without a wrench (See
Figure 2-1).
• Install the converter in a location where there will be no excessive impact or
vibration.

• When mounting the converter directly onto the pneumatic signal pipe, full
consideration must be given to its weight and vibration.
2-3 : Piping
Mounting brackets are supplied with the converter as an option. With the mounting
bracket, the converter can be installed on a 2 inch pipe or a panel.
Figure 2-2 illustrates examples of installing the converter with mounting brackets.

Chapter 3 : Wiring
3-1 : Precautions
CAUTION
• Performing wiring with wet hands or with its power turned on may result in
electrical shock to personnel. Always perform wiring work with dry hands, always
wear gloves and turn the power to the converter off before performing wiring
work.
• Turning on the power in an explosion-protected area while the housing is open can
induce explosion.
• Perform the wiring work correctly while carefully following the specifications.
Incorrect wiring will cause damage to or result in malfunction of the product.
• Use the power supply properly based on the specifications. Incorrect power
supply will damage the product.
• This instrument is designed based on a two-wire system. The power supply line
also functions as a signal line. The wires are routed through the conduit hole on
the side face of the converter and are connected to the terminals. The conduit end
is potted with sealing agent or capped with a sealing plug so the water cannot
permeate into the housing. The connecting wires to the terminals must be drawn
in below the position of where the connection port is located.
• The converter has two grounding terminals: one at the terminal and the other on
the outside face. Either terminal may be used. The grounding terminal must be
connected to a ground having a resistance of 100Ωor less.
3-2 : Power supply
Power supply to the converter should be between 11.5V DC and 30V DC.

4-1 : Maintenance
CAUTION
• If the converter is disconnected from the pipe for maintenance purposes, securely
shut off the pneumatic line to the product. Personal injury could result from the
blowout of air.
• Do not open the housing cover while it is operating in hazardous area. Opening the
cover may induce an explosion.
Check the following on periodic basis:
• Has the housing, cover or grounding cable been damaged?
• Are the grounding cable, cover or housing locking screw loose?
• Are the terminal screws loose?
• Is there any deterioration in the O-rings?
• Is there any leakage from the connection pipes?
