Additional Notes
Installation shall be carried out in accordance with the applicable code of practice by suitably-trained personnel.
If the equipment is likely to come into contact with aggressive substances, then it is the responsibility of the
user to take suitable precautions that prevent it from being adversely affected, thus ensuring that the type
of protection is not compromised.
For products other than PR3200 and PR3202 there are no special checking or maintenance conditions
other than a periodic check. These products which may have aluminium enclosures (powder coated)
should be located where friction sparks with steel objects are avoided. They should also be regularly
inspected to ensure the coating is not damaged

D Where applicable, the address of the importer or repairer will be specified.
E On being put into service, the equipment will be accompanied by a translation of the instructions in the
language
or languages of the country in which the equipment is to be used and by the instructions in the original language.
F In addition to the wording normally applied (e.g. Clean Only With A Damp Cloth) the wording of the label shall
include the words ‘Warning: Danger of propagating brush discharge’ followed by the warning symbol ISO3864 No.
B.3.1 (black exclamation mark in black triangle, meaning: Caution, refer to accompanying documents). The
manufacturer’s instructions shall include details of the ignition hazard caused by propagating brush discharges and
the precautions to be taken to avoid the build up of static charge. (See note 6 above)
Aggressive substances -
Suitable precautions -
e.g. acidic liquids or gases that may attack metals or solvents that may
affect polymeric materials.
e.g. regular checks as part of routine inspections or establishing from
the material's data sheet that it is resistant to specific chemicals
For the maximum cable lengths stated the cable capacitance shall not exceed 200pF/m otherwise the
overall capacitance of Ci plus the cable capacitance shall not exceed 83nF
The equipment may be used with flammable gases, vapours and dust with apparatus group IIC and with
temperature class T4. The apparatus is not permitted for use with dusts that have a layer smouldering
temperature of 135oC or less.
The equipment may be used above surface Group II and Group III and in mining zone Group I.
The equipment is only certified for use in ambient temperatures in the range -20oC to +70 oC and should
not be used outside this range.
Propagating brush discharges are caused by non-conducting fluid flow over a non-conducting plastic
surface. The product shall not be installed in areas where a high fluid flow may occur (for example in the
case of a ruptured process pipe or compressed air pipe).
All repairs are to be carried out by Althen.
