Ambient Operating and Storage Environments
• Store the Product at a temperature of
−
25 to 85°C and a humidity
of 5 to 96%.
• The internal parts may occasionally deteriorate or be damaged. Do
not use the Product in areas outside the derating curves.
• Use the Product at a humidity between 5 to 96%.
• Do not use the Product in locations subject to direct sunlight.
• Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of the Product.
• If the Product has been accidentally dropped, do not use it as its
internal parts may be damaged.
• Minor electric shock, fire, or Product failure may occasionally
occur. Do not disassemble, modify, or repair the Product or touch
interior of the Product.
Installation Environment
• Do not use the Product in locations subject to shocks or vibrations.
In particular, install the product as far away as possible from
contactors or other devices that are a vibration source. Be sure to
mount End Plates (PFP-M) on both ends of the Product.
• Install the Product well away from any sources of strong, high-
frequency noise and surge.
Mounting
• Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Product. Mount the Product
so that air convection will occur around it. Use it in areas within the
derating curves (see
Derating Curves
on page 7).
• The internal parts may occasionally deteriorate and be broken due
to adverse heat radiation.
Do not loosen the screws on the Product.
• Mount as shown below.
• Only products of the same model can be combined and used if the
horizontal separation is less than 15 mm.
Wiring
• The property damage may occasionally occur due to fire If the
insertion distance is not sufficient. When wiring, insert the wiring
material securely all the way in.
• Minor fire may possibly occur. Ensure that input and output
terminals are wired correctly.
• Do not apply more than 40 N force to the terminal block when
inserting wiring or inserting a flat-blade screwdriver into the release
hole.
• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
• Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force. Doing so may cause the wire to break.
• Do not insert more than one wire into each terminal insertion hole.
• Do not pre-solder the ends of the wires. Doing so will inhibit proper
connection.
• If there is a possibility that the Unit will be subject to vibration or
shock, use Wires with Ferrules or Stranded Wires.
• Be sure to remove the sheet covering the product before Turn ON
so that it does not interfere with heat dissipation.
• To prevent wiring materials from smoking or ignition, confirm wire
ratings and use the wiring materials given in the following table.
Recommended Wire
• Use copper stranded wire or solid wire.
• Do not use the solid wire to the power input terminal.
• Use min. 75°C wire.
• Input crossover wiring can be used for the input side of the Product.
If you use crossover wiring for N number of the Products, a current
that is N times the current for a
standalone the Unit may flow to the
input terminals. Take this into consideration when you select
wiring materials.
• Make sure that the current of the power input terminal does not
exceed 35A per pole.
• When connecting to the two poles of the power input terminals, be
sure that the length and
thickness of wires are the same to allow
for well balanced current flows.
