RTU-LP DESCRIPTION
The RTU-LP-ST is a device used to tele-control digital and analogue data via GSM/GPRS
connections. The system architecture is based on a microcontroller, an in-built modem and
arange of inputs/outputs. RTU-LP-ST is suitable for all thetelecontrolapplications onsmall
systems, system parts, data collection and management.
The many accessories such as external aerials, IP65, IP67 protection casings or battery
packs with increased capacity, guarantee a customisable and complete offer for industrial
applications.

INSTALLATION REGULATIONS
In addition to the installation on an IEC EN 60715 omega rail using the S-DIN support with
screws supplied, the RTU-LP device can be housed in an IP65 pre-wired housing (BOX-
RTU-IP65) with battery support and dimensions 290x140x108mm.
Check the order codes in the SOFTWARE and ACCESSORIES paragraph on page 8.
For the wiring, use onlya cablecompliant withthe nationalor harmonised
regulations, having a section suitable to the device consumption and the
installation conditions. Use power cables with a minimum section of
0.25mm².
If externalbatteries are used, the power cable maximum length must not
exceed 3 meters.
Itis MANDATORY touse an antennawith coaxialcable positioned at minimum
50cm fromtheunit.
FACTORY SETTINGS
The RTU-LP device has no factory settings: To proceed with the first configuration, it is
necessary to use the EASY RTU LP software that can be downloaded free of charge from
the software section of the product sheet www.seneca.it/products/rtu-lp-st
