Caution

Installation

Please avoid installing in the following locations.
●
• Locations in which the ambient temperature falls outside the range of –10 to 50 °C when equipment is in use.
• Locations with rapid temperature changes, leading to dew condensation
• Locations with corrosive gases (especially sulfide gas, ammonia, etc.) or flammable gases.
• Locations with vibration or shock directly. (Vibration and shock may cause output relay malfunction.)
• Locations in contact with water, oil, chemicals, steam or hot water. (If the equipment gets wet, there is a risk of
electric shock or fire, so have it inspected by Fuji distributor.)
• Locations with high concentrations of atmospheric dust, salt or iron particles.
• Locations with large inductive interference, resulting in static electricity, magnetic fields or noise
• Locations in direct sunlight.
• Locations that build up heat from radiant heat sources, etc.
Recommended site conditions
●
• A place where the ambient humidity during operaion is between 45 to 85% RH.
This equipment is a class A , for industrial locations, equipment. Do not use this equipment in domestic
●
establishment, such as residential areas, or it may cause radio interference. If you use this equipment in
domestic locations, take adequate measures on the outside of the equipment to reduce radio interference.
Under the requirement of EMC standard, the maximum length of external cable including a sensor to be
●
connected to this equipment is 30 m. Do not connect the sensor longer than 30 m.

Panel mounting

Insert the controller unit into the panel cutout from the front, and then put the mounting bracket from the rear.
●
The mounting bracket should be pushed in until the controller is securely fixed to the panel. If there is a slight
gap remaining, gently tighten the two screws until the gap disappears. (Make sure not to over tighten the screws,
as doing so may result in the mounting bracket separating from the stopper.)
The front of this equipment is waterproof in compliance with NEMA-4X standards (IP66- equivalent). To effect
●
waterproof, the included packing is shall be attached between the controller and the panel according to the
guidelines below. (Incorrect attachment may cause the equipment to lose its waterproof capabilities.)
(1) As shown in Fig. 1, insert to the panel after attaching the packing to the equipment case.
(2) As shown in Fig. 2, tighten the screws of the mouthing bracket so that no gaps can remain between the
equipment face, the packing and the panels. Once finished, confirm that there are no changes in shape such
as displaced or improperly-fitted packing, etc. as shown in Fig. 3

Front
If the panel does not have enough strength, gaps may develop between the packing and the panel to lose
●
waterproofing capabilities.
In order to aid heat dissipation, do not block the sides of the equipment.
