GT3F Series Timers

Instructions: Wiring Inputs

Switches & Pilot Lights To avoid electric shock, do not touch the input signal terminal during power voltage application.
Inputs of GT3F

Never apply the input signals to two or more GT3F timers using the same contact or transistor.

On the GT3F timers, connect the input signals to terminal No.1 and 4 only on the 8-pin type; connect the input signals to terminal No. 6 and 7 only on the 11-pin type.
Relays & Sockets ing.
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 wir-

The GT3F, consisting of a high-impedance circuit, may not be reset due to the infl uence of an inductive voltage or residual voltage caused by a leakage current. If not
reset, connect an RC fi lter or bleeder resistor between power terminals so that the voltage between power terminals can be reduced to less than 15% of the rated
voltage.
