Inputs Inputs
To avoid electric shock, do not touch the input signal terminal during power voltage application.
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.)
[Incorrect]
Input
Contact or Transistor
In a transistor circuit for controlling input signals, with its primary and secondary power circuits isolated, do not ground the secondary circuit.
Connect the input signal terminals of the GT3A timers to Terminal No.2 only. Never apply voltage to other terminals; otherwise, the internal circuit may be damaged.
Input signal lines must be made as short as possible and installed away from power cables and power lines. Use shielded wires or a separate conduit for
input wiring.
