3.4.2 Turning off the Module

There are two ways to Turn OFF the G510: Asserting the POWER_ON signal to low state for at least 3
Seconds then the module will Power Down automatically. Or alternatively the module can be Power OFF
using AT Command, please refer to <G5-Family AT Commands User Manual>.
1. POWER_ON Signal
The POWER_ON signal is set high using an internal pull up resistor when power is applied to module.
When the POWER_ON signal is falling edge and keeping low for a minimum of 3 seconds will turn
module off.
This will initiate a normal power-off process, which includes disabling of all applications interfaces
(UART, SIM card, etc.) and logout the network connection.
