2) General
2.1) Product Description
The SA380-IT is designed to facilitate the continuous monitoring of circuit voltage and resistance to earth of up to 5 independent circuits.
The SA380-IT has built-in communications hardware in the form of a GSM modem and features Ethernet connectivity. This allows the
SA380-IT to connect to cloud-based Enterprise Asset Management Systems (EAMS).
It is wise to conduct a on monitored circuits both prior to, and after installation, but energising the manual insulation test before
SA380-IT. This will help verify correct installation of the measurement circuit wiring.
A between Functional Earth and Loop Earth connections after installation, but energising SA380-IT manual continuity test before
will help verify correct installation of the earth-loop circuit wiring.
When conducting manual insulation testing on monitored circuits after commissioning, the SA380-IT must be either:
Prevented from attempting measurement (see section 4.4.5).
Physically disconnected from the monitored circuit.
Powered-down.
Failure to do so will result in incorrect readings.
ontinuous monitoring. It facilitates: Maintenance Reduction and Failure prevention are best realised through c
The removal of the requirement for time-consuming and dangerous physical inspection and measurement.
The ability to predict, schedule and fix developing earth faults

Key Features:
Independent monitoring of up to 5 circuits, each circuit can be one of the following systems:
Single phase IT AC system up to 160 V RMS.
Single phase IT AC system up to 160 V RMS with galvanically connected rectifiers.
