3 Electrical Installation
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 15 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> 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
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
13849 Cat.3, IEC/EN 61508 SIL2, Insulation coordination: class 1.
