CAUTION
POTENTIAL FOR SHORT CIRCUITS AND/OR POWER-UP SPIKES
Provide external fuses on the operating voltage to protect the module. Appropriate fuse values are shown in the wiring illustration. An unprotected module may be subject to short circuits and/or power-up spikes.
Failure to follow these instructions can result in injury or equipment damage.
