INSTALLATION 

 
 
 
 
 
 
 
 
 
 
 
 
 
To install the GSM-CTL-AC, you need to power on the board with AC100V to 230V. and 

also connect the relay output according to your project. The relay contacts can stand 

230V 30A 

maximum

, this is enough for its operation but 

don't try to switch higher voltages or currents

You should install the GSM-CTL-AC in a place where there is GSM signal coming from the 
operator you want to use. Check it with a phone before proceeding with the installation. If you 
need to install the device in a place with little signal, you may consider using an external antenna 
that we may supply as an option to be purchased separately with 50cm cable. 

You should then insert the SIM Card of the operator you want to use with the right direction 

according to the following pictures. 

!Note! : You must remove the PIN request from the SIM before inserting it in the

 

unit

, otherwise the device will not work. In order to do so, insert the SIM in a phone and 

disable the PIN request (usually there is a security menu that enables you to do so). 
 
 
 
 
 
 
 
 
 

 
 
 
 
 
 

 

 

1.Slide back the SIM door and 

lift it up 

2.Slide the SIM Card into the 

SIM door making sure that 
the clipped corner of the SIM 
card lines up with the clipped 
corner of the SIM holder 

3.Close the SIM door 
4.Slide the SIM door to lock the 

SIM card in place 

Please read this entire manual before installation !!!!
