The intrinsically safe circuits are galvanically isolated from parts which can be grounded.
The metallic parts of OPTIBAR * 5060 VGK5/6/D*A/W/V C/U/0/H/T are electrically connected with
the ground terminals.
For applications requiring equipment category 1G or 1/2G, the intrinsically safe supply and
signal circuits must correspond to protection level ia.
For applications that require equipment category 1G or 1/2G, it is preferable to connect the
OPTIBAR * 5060 VGK5/6/D*A/W/V C/U/0/H/T to appropriate equipment with galvanically isolated,
intrinsically safe circuits.

In protection type intrinsic safety Ex ia IIC
Only for connection to the display and adjustment module.
In the double chamber housing version, the display and
adjustment module in the terminal compartment should only
be equipped if there is no external display unit or
OPTIBAR * 5060 with electronics S or T connected.
