General information
The VEGADIS 176 Ex (DIS176.ICSI) is an intrinsically safe, scalable, digital indicating instrument
without external energy for installation in hazardous areas of zone 1. It is looped into intrinsically
safe 4 … 20 mA circuits. The voltage supply for power supply of the electronics is taken from the
4 … 20 mA circuit.
The VEGADIS 176 Ex (DIS176.ICSI) is suitable for use in hazardous atmospheres of all combusti
-
ble materials of explosion group IIA, IIB and IIC for applications requiring EPL-Gb instruments.
If the VEGADIS 176 Ex (DIS176.ICSI) are installed and operated in hazardous areas, the general Ex
installation regulations IEC 60079-14 as well as these safety instructions must be observed.
The operating instructions as well as the installation regulations or standards that apply for explo
-
sion protection of electrical systems must generally be observed.
The installation of explosion-endangered systems must always be carried out by qualified person
