Caution
• To prevent an electric shock, prior to VM Unit installation be sure to
check that the GP/GLC/ABS and VM Units are not connected to a power
supply.
• Do not touch the circuit board attached to the inner face of the VM Unit.
• Do not modify the design of the VM Unit. Doing so may cause a fire or
electric shock.
• Design your system so that the equipment will not malfunction due to a
communication fault between the GP and a PLC. This is to prevent
any possibility of bodily injury or equipment damage.
To prevent VM damage
• Do not allow water, liquids, or metal objects to enter the VM Unit. Otherwise, a
malfunction or electric shock may occur.
• Do not use the VM Unit in areas where large, sudden temperature changes can
occur. These changes can cause condensation to form inside the unit, possibly
causing the unit to malfunction.
• Do not use or store the VM Unit in direct sunlight or in excessively dusty
environments.
• Since the VM Unit is a precision instrument, do not use or store it where large
shocks or excessive vibration can occur.

are present in the air, or where chemicals can adhere to the unit.
