S8VK-T
13
Wiring
• Connect the ground completely. A protective earthing terminal
stipulated in safety standards is used. Electric shock or malfunction
may occur if the ground is not connected completely.
• Minor fire may possibly occur. Ensure that input and output
terminals are wired correctly.
• Do not apply more than 75-N force to the terminal block when
tightening it.
• Be sure to remove the sheet covering the Product for machining
before power-ON so that it does not interfere with heat dissipation.
• To comply with safety standards and to ensure equipment safety,
connect the input to the S8VK-T through one of the following
Breakers or Fuses.
Power circuit-breakers
Note: Do not use the S8VK-T96024 with a DC input.
• Use the following material for the wires to be connected to the
S8VK-T to prevent smoking or ignition caused by abnormal loads
or phase failure.
• Wire the input as shown in the following figures depends on your
power distribution system. Do not connect the neutral line in a
3-phase, 4-wire system.
Recommended Wire Type/Cross-sectional Area and Stripping Length
• The wire insertion hole, and applicable screwdriver of the terminal block are as follows.
Installation Environment
• Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far away as
possible from contactors or other devices that are a vibration
source. For usage onboard a ship, always attach an End Plate
(PFP-M) to both sides of the Power Supply to hold the Power
Supply in place.
• Install the Power Supply well away from any sources of strong,
high-frequency noise and surge.
Operating Life
• The life of a Power Supply is determined by the life of the
electrolytic capacitors used inside. Here, Arrhenius Law applies,
i.e., the life will be cut in half for each rise of 10°C or the life will be
doubled for each drop of 10°C. The life of the Power Supply can
thus be increased by reducing its internal temperature.
Ambient Operating and Storage Environments
• Store the Power Supply at a temperature of −40 to 85°C and a
humidity of 0% to 95%.
• Do not use the Power Supply in areas outside the derating curve
otherwise, internal parts may occasionally deteriorate or be
damaged.
• Use the Power Supply at a humidity of 0% to 95%.
• Do not use the Power Supply in locations subject to direct sunlight.
• Do not use the Power Supply in locations where liquids, foreign
matter, or corrosive gases may enter the interior of Products.
