In protection type intrinsic safety Ex ia IIC
For connection to the intrinsically safe circuit or for
connection of an OPTIBAR * 5060 VGK5/6/D*A/W/V C/U/0/H/T
with integrated electronics S or T for electronic differential
pressure measurement.
The rules for interconnecting intrinsically safe circuits
between
OPTIBAR * 5060 VGK5/6/D*A/W/V C/U/0/H/T and
OPTIBAR * 5060 with electronics S or T are observed when the
overall inductance and overall capacitance of the connecting
cable between
OPTIBAR * 5060 VGK5/6/D*A/W/V C/U/0/H/T and
OPTIBAR * 5060 with electronics S or T

when using the supplied connection cable
between OPTIBAR * 5060 VGK5/6/D*A/W/V C/U/0/H/T and
OPTIBAR * 5060 with electronics S or T.
