TP301 – Certifications Information
A.2
Instrinsic Safety / Non Incendive application
In hazardous areas with intrinsic safety or non-incendive requirements, the circuit entity parameters and
applicable installation procedures must be observed.
The instrument must be connected to a proper intrinsic safefy barrier. Check the intrinsically safe parameters
involving the barrier and equipment including the cable and connections. Associated apparatus ground bus shall
be insulated from panels and mounting enclosures. Shield is optional, when using shielded cable, be sure to
insulate the end not grounded.
Cable capacitance and inductance plus Ci and Li must be smaller than Co and Lo of the Associated Apparatus.
It is recommended do not remove the housing covers when powered on.
Explosionproof / Flameproof application
Only use Explosionproof/Flameproof certified Plugs, Adapters and Cable glands.
The electrical connections entries must be connected using a conduit with sealed unit or closed using metal cable
gland or metal blanking plug with at least IP66.
Do not remove the housing covers when powered on.
Enclosure
The electronic housing and sensor threads installed in hazardous areas must have a minimum of 6 fully engaged
threads.
The covers must be tightening with at least 8 turns, to avoid the penetration of humidity or corrosive gases, and
until it touches the housing. Then, tighten more 1/3 turn (120º) to guarantee the sealing.
Lock the housing and covers using the locking screw.
Degree of Protection of enclosure (IP)
IPx8: Second numeral meaning continuous immersion in water under special condition defined as 10m for a
period of 24 hours (Ref: IEC60529).
IPW/ TypeX: Supplementary letter W or X meaning special condition defined as saline environment tested in
saturated solution of NaCl 5% w/w at 35ºC for a period of 200 hours (Ref: NEMA 250/ IEC60529).
For enclosure with IP/IPW/TypeX applications, all NPT threads must apply a proper water-proof sealant (a non-
hardening silicone group sealant is recommended).
