Instructions: Wiring Inputs for GT3 Series

Switches & Pilot Lights To avoid electric shock, do not touch the input signal terminal during power voltage application.
Inputs Inputs

When connecting the input signal terminals of two or more GT3A timers to the same contact or transistor, the input terminals of the same number should be con-
nected. (Connect Terminals No.2 in common.)
