■ Output Terminals
WARNING! Sudden Movement Hazard. The logic of terminals DM+/DM- is inverted between drive models CIMR-LA and
CIMR-LF. Check all wiring to ensure that the sequence is correct after installing the drive and connecting any other devices.
Improper wiring connections could result in death or serious injury.
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 the output to malfunction when the terminal is activated.

<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.
<2> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN 61800-5-2, ISO/EN
13849 Cat.3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
Type
<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 Figure 3.19 when driving a reactive load such as a relay coil. Make sure the diode rating is greater
than the circuit voltage.
<3> Terminals H1, H2, DM+, and DM- on 600 V class models are designed to the functionality, but are not certified to IEC/EN 61800-5-2, ISO/EN
