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.
