Installation / startup
Two standard options are available for mounting the GSM Module M1 :
• Retaining clip
•Velcro
Before applying the velcro, make sure that the surface of the M1 (recess provided in
center of base) and the corresponding surface are free of dust and oil.
The mounting location must comply with the following environmental conditions:
• Temperature range -20 °C – +55 °C for full operability
• Temperature from insolation < 110 °C
• Light condensation permissible
Power is supplied via the cable included in the scope of supply. The relevant wires are
marked as follows:
Red POWER +8 V – +24 V DC
Violet IGNITION(ON/OFF)
Brown GND Ground
The GSM Module M1 switches on when a positive voltage of 5 - 24 V is applied to IG-
NITION if a voltage of 8 - 24 V is simultaneously applied to POWER.
The module switches off when a voltage of less than +1 V is applied to IGNITION. An
existing call is correctly disconnected. This voltage must be applied for a minimum of
550 ms.
Important:
Be sure to switch off the module using IGNITION; simply disconnecting the power sup-
ply at POWER can damage the SIM if it is being written to at the time.
Nominal voltage: 13,2 V DC
Extreme voltage: 8 - 32 V DC
