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.
• Use the following material for the wires to be connected to the
S8JX to prevent smoking or ignition caused by abnormal loads.

* The rated current for the output terminals on the S8JX-G30005@@, S8JX-
G30012@@, S8JX-G60005@, S8JX-G60012@, S8JX-P300@@ and S8JX-
P600@@ is 60A for each terminal. The rated current for the output terminals
on the S8JX-G30024@@, S8JX-G30048@@, S8JX-G60024@, and S8JX-
G60048@ is 20 A for each terminal. Use two terminals together if the current
flow is higher than the rated terminal current.

Method of Manufacturing Connector Harness for
Signal I/O
For S8JX-P Series 300-/600-W models, PHD connectors
manufactured by JST Mfg. Co., Ltd. should be used.
Connector
S12B-PHDSS
used
Housing
PHDR-12VS
Terminal
SPHD-001T-P0.5 or BPHD-001T-P0.5
To ensure correct wiring, the following points should be borne in mind
when manufacturing the connector. It is recommended that the JST
Mfg. Co., Ltd. catalog be read for further details.
• Electric cable size AWG26 to AWG22 should be used.
• The electric cable sheath stripping length should be approximately
2.3 mm.
• Dedicated tool YC (Manufactured by JST Mfg. Co., Ltd.) should be
used for crimping of terminals and wiring.
• Although UL1007 (Twisted wire) and other equivalent twisted wires
can be used for electric cables, UL1061 with a small outer sheath
shape and equivalent twisted wires should be used for AWG22.
• When accommodating crimped terminal wiring in the housing,
insert the wiring as far as possible to the back of the housing in a
single movement and check for an audible click. In addition, check
that wiring inserted in the housing is properly locked in place.
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.
• Install the Power Supply well away from any sources of strong,
high-frequency noise and surge.
Ambient Operating and Storage Environments
• Store the Power Supply at a temperature of −25 to 65°C (−25 to
75°C for S8JX-P series) and a humidity of 25% to 90%.
• The Internal parts may occasionally deteriorate or be damaged.
Do not use the Power Supply outside the derating range (i.e., the
area shown by shading
in the derating curve diagram on
1
page 44.)
• Use the Power Supply at a humidity of 25% to 85%.
• Do not use the Power Supply in locations subject to direct sunlight.
• Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of the Product.
Overload Protection
• Internal parts may possibly deteriorate or be damaged if a short-
circuited, overload or peak load state continues during operation.
• Internal parts may possibly deteriorate or be damaged if the Power
Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such
applications.
Charging a Battery
When connecting a battery at the load, connect an overcurrent
limiting circuit and overvoltage protection circuit.
