HAZARD OF ELECTRIC SHOCK, EXPLOSION,
OR ARC FLASH
Failure to follow these instructions will result in death or serious injury.

-
The SG (signal ground) and FG (frame ground) terminals are connected internally in this product.
-
When the FG/PE terminal is connected, be sure the wire is grounded. Not grounding this product can result in excessive electromagnetic interference (EMI).
-
Make sure the ground wire is either the same or heavier gauge than the power wires.
-
Do not use aluminum wires in the power supply's power cord.
-
To prevent the possibility of a terminal short, use a pin terminal that has an insulating sleeve.
-
If the ends of the individual wires are not twisted correctly, the wires may create a short circuit.
-
The conductor type is solid or stranded wire.
-
Use copper wire rated for 75 °C (167 °F) or higher.
-
For AC input, use a maximum 20 A branch circuit protective device.
-
AC models obtain UL certification for use in environments rated at Overvoltage Category II or lower.
-
Use the SELV (Safety Extra-Low Voltage) circuit and LIM (Limited Energy) circuit for DC input.
*1 Since a high level of current flows in the DC model, thick wires are recommended to minimize voltage drops due to wiring.
*2 When using stranded wires, confirm the level of current supported by the wire.
