CERTIFICATES FOR USE IN HAZARDOUS AREAS

6.1. Directive ATEX – intrinsically safe version

Displays may be used in potentially explosive atmospheres in accordance with the following explo-

sion-proof designations:

II 2G Ex ia IIC T4 Gb

II 1D Ex ia IIIC T110°C Da

KDB 16 ATEX 0006

The displays are designed and manufactured in accordance with requirements of the following stand-

ards: EN 60079-0:2012 + A11:2013, EN 60079-11:2012.

Connections in potentially explosive zones are presented in p.8.4.

Allowable parameters based on the KDB 16 ATEX 0006. certificate is given in 6.2.

6.2. Allowable parameters for supplying of the displays (based on the certificate KDB

16 ATEX 0006)

Displays with cooperating transmitters shall be supplied from the supplying devices having

appropriate certificates of intrinsic safety, which parameters of outputs to potentially explo-

sive zones shall not exceed allowable supply parameters for the displays.

Substitute inductance of transmitter circuit with display Liz = Lip

where Lip - input inductance of the transmitter.

Substitute capacitance Ciz of circuit of the transmitter with display equals to:

for input capacitance of the transmitter Cip ≤ 25 nF;

Ciz = 25 nF

Ciz = Cip

for input capacitance of the transmitter Cip > 25 nF.

Calculated values of substitute inductance and capacitance of the circuit shall be increased by induct-

ance and capacitance of the cable.
