CAUTION:
High voltage transients may occur when switching inductive loads such as
some contactors or solenoid valves. Through the internal contacts, these
transients may introduce disturbances which could affect the performance of
the instrument.
For this type of load it is highly recommended that a “snubber” is connected
across the normally open contact of the relay switching though load. The
snubber recommended consists of a series connected resistor/capacitor
(typically 15nF/100 Ohms). A snubber will also prolong the life of the relay
contacts. A snubber should also be connected across the output of a trip
output to prevent false triggering under line transient conditions.
