AC/DC Power Cord Preparation

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Remove all power from the device before removing any covers or elements of the system, and prior to installing or removing any accessories, hardware, or cables. Remove power before wiring this product’s power terminals. Always use a properly rated voltage sensing device to confirm power is off where and when indicated. Replace and secure all covers or elements of the system before applying power to this product. Use only the specified voltage when operating this product. The DC model is designed to use 24 Vdc, and the AC model is designed to use 100 to 240 Vac. Always check whether your device is DC or AC powered before applying power. Since this product is not equipped with a power switch, be sure to connect a power switch to the power supply. Be sure to ground this product’s FG/PE terminal. Failure to follow these instructions will result in death or serious injury.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Remove all power from the device before removing any covers or elements of the system, and prior to installing or removing any accessories, hardware, or cables.
Remove power before wiring this product’s power terminals.
Always use a properly rated voltage sensing device to confirm power is off where and when indicated.
Replace and secure all covers or elements of the system before applying power to this product.
Use only the specified voltage when operating this product. The DC model is designed to use 24 Vdc, and the AC model is designed to use 100 to 240 Vac. Always check whether your device is DC or AC powered before applying power.
Since this product is not equipped with a power switch, be sure to connect a power switch to the power supply.
Be sure to ground this product’s FG/PE terminal.

Failure to follow these instructions will result in death or serious injury.

NOTE:

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.
If the ends of the individual wires are not twisted correctly, the wires may create a short circuit. When inserting a wire into the connector, hold down the opening button and insert the wire while the internal spring is depressed. Alternatively, you can crimp and insert either a pin terminal or ferrule terminal.
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 Thick wires are recommended to minimize voltage drops in the wire.

^*2 When using stranded wires, confirm the allowable current of the wire.

AC grounding wire
Recommended cross section	2 mm² or more (14 AWG or greater)
Ring terminal size^*1	Φ4.3 mm (0.17 in) or more 7.2 mm (0.28 in) or less

^*1 To prevent a short circuit caused by loose screws, use a crimp-type terminal with an insulating sleeve.
