Application Conditions - Vega VEGAPULS PS6.CXH Serie Instrucciones De Seguridad

Adjustment and indication module
circuit:
(spring contacts in the electronics
compartment, additionally in the
connection compartment with
double-chamber housing version)
The intrinsically safe circuits are galvanically separated from parts which can be grounded.
For applications requiring instruments of category 2 G, the intrinsically safe supply and signal circuit
must correspond to category ia or ib; when connecting to a circuit of category ib, the flame proofing
identification is EEx ib IIC T6.
For applications requiring category 1 G or 1/2 G instruments the intrinsically safe supply and signal
circuit must correspond to category ia.
For applications requiring category 1 G or 1/2 G instruments all VEGAPULS PS6*.CX***H*** should
be connected preferably to accessory equipment with galvanically separated intrinsically safe circuits.

4. Application conditions

The max. permissible ambient temperatures in dependence of temperature class are mentioned in the
following tables:
Category 1 G instruments
T class
T5
T4, T3, T2, T1
The 80% consideration of EN 1127-1, sect. 6.4.2 is taken into account with the permissible
ambient temperatures on the sensor and electronics.
