Power Cord Preparation
Before using your power cord:
 Verify that the ground wire is the same gauge or heavier than the power wires.
 Do not use aluminum wires for the power supply’s power cord.
 If the conductor end (individual) wires are not twisted correctly, the end wires may either
short loop to each other or against an electrode. To avoid this, use D25CE/AZ5CE cable
ends.
 Use wires that are 0.75 to 2.5 mm 2 (18 to 12 AWG) for the power cord, and twist the wire
ends before attaching the terminals.
 The conductor type is solid or stranded wire.
 To reduce electromagnetic noise, make the power cord as short as possible.

Connecting the Power Cord
The table explains how to connect the power plug:
Connection Wire
+ 24 Vdc
- 0 Vdc
FG Grounded terminal connected to the unit chassis
Step Action
1 Confirm the power cord is not connected to the power supply.
2 Check the rated voltage and remove the "DC24V" sticker on the DC power supply
connector.
3 Remove 10 mm (0.39 in.) of the vinyl membrane off the ends of the power code wires.
4 If using stranded wire, twist the ends. Tinning the ends with solder reduces risk of
fraying and ensures good electrical transfer.
5 Push the Opening button with a small and flat screwdriver to open the desired pin hole.
