7 wiring guidelines terminal board note: control outputs 1 and 2 are protected by v aristor against an inductive load up to 0.5 amps. All other outputs, or external contacts in series with the instrument outputs, need an external snubber network (rc) across the terminals: c r in accordance with the ...

11 b.2) inductive loads high voltage transients can occur when switching inductive loads. It is recommended to install an additional rc network across the internal contacts as shown. The same problem can occur when a switch is used in series with the internal contacts. L o a d c r p o w e r l in e i...
