<1> Setting jumper S3 for an external power supply makes the wire jumper between terminals H1, H2, and HC ineffective. Remove the wire jumper
and connect an external power supply that can supply terminals H1, H2, and HC continuously.

Output Terminals
Table 3.7 lists the output terminals on the drive. Text in parenthesis indicates the default setting for each multi-function
output.
Note: Multi-function relay output terminals are rated at a minimum of 10 mA. If less than 10 mA is required, use the photocoupler
outputs (P1-C1, P2-C2). Using the wrong current output level may cause undesirable effects when the terminal is activated.

<1> Refrain from assigning functions to terminals M1 thru M6 that involve frequent switching, as doing so may shorten relay performance life.
Switching life is estimated at 200,000 times (assumes 1 A, resistive load).
<2> Connect a suppression diode as shown in
than the circuit voltage.
