1.1 General notes
These supplementary instructions apply to versions of the loop powered control and calibration
unit for use in hazardous areas that fall in intrinsically safe protection type "i", equipment
category II 2 G or EPL Gb.
It complements the standard documentation for versions for use in non-hazardous areas.
The information given in these instructions contains only the data relevant to explosion
protection.
The technical details given in the standard documentation for the non explosion-protected
versions remain unchanged unless they will be excluded or replaced by this instruction.
1.2 EU conformity
The manufacturer declares with the EU declaration of conformity on his own responsibility
conformity with the protection goals of directive 2014/34/EU for use in hazardous areas with gas.
Conformity with harmonised standards was checked by a notified body in accordance with
EN IEC 60079-0:2018 and EN 60079-11:2012.
The EU declaration of conformity for the equipment category II 2G is based on the following EU
type examination certificate:
The "X" after the certificate number refers to special conditions for safe use of the device, which
have been listed in these instructions.
If needed the EU type examination certificate can be downloaded from the manufacturer's
website.
1.3 UK conformity
The manufacturer declares with the UK declaration of conformity on his own responsibility
conformity with the protection goals of "Equipment and Protective Systems Intended for use in
Potentially Explosive Atmospheres Regulations 2016 No. 1107" for use in hazardous areas with
gas. Conformity with the regulations was checked in accordance with EN IEC 60079-0:2018
and EN 60079-11:2012 by an UK Approved Body.
The UK declaration of conformity is based on the UK type examination certificate issued by CSA
Group:
The "X" after the certificate number refers to special conditions for safe use of the device, which
have been listed in these instructions.
If necessary, the UK type examination certificate can be downloaded from the manufacturer's
website.

1.6 Safety instructions
If these instructions are not followed, there is a risk of explosion.
Assembly, installation, start-up and maintenance may only be performed by personnel trained in
explosion protection!
This product shall be used in explosive atmospheres together with approved associated
equipment. Follow the standard manual for the loop powered control and calibration unit of the
associated equipment when connecting.
The connecting cable between the loop powered control and calibration unit and the associated
equipment should be an insulated shielded cable; connect the shield to functional earth in a safe
area.
QPS LR1322-14
CAUTION!
The operator or his agent is responsible for observing any additional standards, directives or
laws if required due to operating conditions or place of installation.
This applies in particular to the use of easily detachable process connections when measuring
flammable media.
WARNING!
The user shall not change the configuration in order to maintain/ensure the explosion protection
performance of the control and calibration unit.
WARNING!
For use and maintenance in explosive atmospheres, observe the warning "POTENTIAL
ELECTROSTATIC CHARGING HAZARD". For further information refer to Electrostatic charge on
page 15
.
CAUTION!
Operating conditions and place of installation may require compliance with additional standards,
directives or laws. The responsibility for compliance rests solely with the operator or his agent.
