Mounting
To improve the long-term reliability of devices, give due
consideration to heat dissipation when mounting. With the S8T-
DCBU-01, heat is dissipated by natural convection. Mount Blocks
in a way that allows convection in the atmosphere around them.
When cutting out holes for mounting, make sure that cuttings do
not enter the interior of the products.
Before turning the Power Supply ON, be sure to remove sheets
that were used as covers during mounting, and make sure that
heat release is not obstructed.
Connect the S8T-DCBU-01 to the right or left end of S8TS-
06024
Basic Blocks.
Wiring
Sufficiently ground the Power Supply, otherwise an electric shock
may occur or the Power Supply may malfunction.
Be sure to wire I/O terminals correctly.
When tightening the terminals, do not exert a force of 100N or
more on terminal blocks or connector terminals.
To prevent short circuits across terminals caused by contact with
foreign objects, close the Terminal Block cover before use.
Use wire shown in the following table to prevent smoking or
ignition of wiring due to overloading or other abnormalities.
Recommended Wire Size
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. Be sure to mount End Plates (PFP-M) on both ends of the
Power Supply.
Install the Power Supply well away from any sources of strong,
high-frequency noise.
Operating and Storage Environments
Do not use or store the Power Supply in the following locations.
Doing so may result in failure, malfunction, or deterioration of
performance characteristics.
• Do not use in locations subject to direct sunlight.
• Do not use in locations where the ambient temperature exceeds
the range of the derating curve.
• Do not use in locations where the humidity is outside the range
25% to 85%, or locations subject to condensation due to sudden
temperature changes.
• Do not store in locations where the ambient temperature is
outside the range
−
25 to 65ºC or where the humidity is outside
the range 25% to 90%.
• Do not use in locations where liquids, foreign matter, corrosive
gases, or flammable gases may enter the interior of products.
• Follow the battery specifications regarding use and the
environment for storing battery holders with a battery installed.
When batteries are used for a prolonged period, observe the
following two points:
• Charge the batteries at the cycle specified by the battery
manufacturer. The battery capacity also decreases due to self-
discharge during storage.
• Turn the battery holder switch OFF. Otherwise, battery
discharge will progress due to leakage current.
Bus Line Connectors
Do not apply sudden shocks (e.g., by dropping) to the Bus Line
Connectors. Doing so may result in damage.
DIN Track Mounting
To mount the Block on a DIN track, hook portion (A) of the Block
onto the track and press the Block in direction (B).
To dismount the Block, pull down portion (C) with a flat-blade
screwdriver and pull out the Block.
