Hazardous location

Caution: Only use the Endress+Hauser battery pack of type BU191
from serial number: 14/01/xxxxxxxx as specified in the
Operating Instructions.
Attention : Utiliser exclusivement un bloc-pile Endress+Hauser detype BU191 mentionné dans le manuel de mise en service à partir
du numéro de série : 14/01/xxxxxxxx.

Cl. I, Div. 2, Groups A, B, C, D
Cl. II and III, Div. 2, Groups F, G (only for NPT conduit entries not for plastic enclosure F32)
1. Install per the Canadian Electrical Code using threaded metal conduit.
2. Intrinsic safety barrier not required. Max. ambient temperature: 70°C.
3. Warning: Explosion hazard - Do not disconnect or open equipment
when area is known to be hazardous.
Avertissement : Risque d'explosion - Ne pas déconnecter ni ouvrir
l'appareil si la zone est explosible.
4. Warning: Substitution of components may impair suitability for Cl. I, Div. 2.
Avertissement : La substitution de composants peut rendre ce matériel
inacceptable pour les emplacements de Cl. I, Div. 2.

Hazardous Locations Installation
1. Installation per Electrical Code of the country in use mandatory.
2. Intrinsically safe and associated equipment connected to the SWA70
must be CSA certified for the country in use and must have entity
parameters that satisfy the following conditions:Voc (Uo) £ Vmax (Ui), Isc (Io) £ Imax (Ii), Po £ Pi,Ca (Co) ³ Ci + Ccable, La (Lo) ³ Li + Lcable.
3. Warning: Substitution of components may impair intrinsic safety.
Avertissement : La substitution de composants peut compromettre lasécurité intrinséque.
4. Use supply wires suitable for 5°C above surrounding.
5. Batteries may be changed in a Cl. I area known to be hazardous.
For Cl. II and Cl. III: WARNING - Explosion hazard - do NOT replacebattery unless the area is known to be NON - hazardous.
Replace only with Endress+Hauser SWA70 battery pack.
6. Battery unit should not be crushed, punctured or otherwise damaged.
Such abuse may impair the electrical safety.
Dispose of used battery units in an enviromentally compatible manner.
Observe national regulations on waste disposal.
7. Where this device (SWA70-C12****) is used to replace an older version(SWA70-C11**** or OSWA-CC1****) in an existing hazardous locationinstallation, caution must be taken to ensure compatibility of the new IS
entity parameters (per IS Control Drawing 960018577) with existing
interconnected devices as these are different from the older versions(ref. previous Control Drawing 960009795-*).
