ENGLISH
Switching of inductive devices such as relay coils and motors results
in high voltage transients from back electromotive force (EMF). To
monitor this type of circuit, use an isolated power supply, such as the
24 Vdc power supply included with the PM8M26, and an auxiliary
contact on the circuit breaker or switch.

CAUTION
VOLTAGE TRANSIENTS OVER 500 V CAN DAMAGE DIGITAL
INPUTS
• Do not use digital inputs to directly monitor circuits with highly
inductive loads.
• Use auxiliary contacts and isolated power supply when
monitoring inductive loads.
Failure to follow this instruction will result in equipment
damage.
