- Zone 20, Class I, Zone 0

- AEx ia IIC T4

- Tamb. –40°C to 80°C

• Non-Incendive for:

- Class I, II, III; Groups A - D, F, G; Divisions 2.

- Class I, Zone 2, Group IIC T4.

- Tamb. –40°C to 80°CEnclosure: Type 4X

• Temp. Code: T4

• Amb. Temp.: –40°C to 80°C

• Enclosure: “Type 4X”

Note 2. Electrical Data

• Intrinsically safe ratings are as follows:

Maximum Input Voltage (Vmax/Ui) = 24 V

Maximum Input Current (Imax/Ii) = 150 mA

Maximum Input Power (Pmax/Pi) = 0.85 W

• Installation Requirements

Uo ≤ Ui, Io ≤ Ii, Po ≤ Pi,

Co ≥ Ci + Ccable, Lo ≥ Li + Lcable

Voc ≤ Vmax, Isc ≤ Imax,

Ca ≥ Ci + Ccable, La ≥ Li + Lcable

Uo, Io, Po, Co, Lo, Voc, Isc, Ca and La are parameters of barrier.

Note 3. Wiring

All wiring shall comply with Canadian Electrical Code Part I and Local Electrical Codes.

• For an ambient temperature ≥ 70°C, heat resistant cables shall be used with a

rating of at least 20°C above the ambient temperature.

• In hazardous location, wiring shall be in conduit.

WARNING: A SEAL SHALL BE INSTALLED WITHIN 50 cm OF THE

ENCLOSURE.

When installed in Division 2,“FACTORY SEALED, CONDUIT SEAL NOT

REQUIRED”.

• In hazardous location, wiring shall be in conduit.

WARNING: A SEAL SHALL BE INSTALLED WITHIN 50 cm OF THE

ENCLOSURE.

UN SCELLEMENT DOIT ÊTRE INSTALLÉ À MOINS DE 50 cm DU

BOÎTIER.

• When installed in Division 2,“FACTORY SEALED, CONDUIT SEAL NOT

REQUIRED”.

Une fois installé dans la Division 2, «scellés en usine, CONDUIT SEAL PAS

NÉCESSAIRE".

Note 4. Installation

• All wiring shall comply with local installation requirements.

• In any safety barreir used output current must be limited by a resistor 'R' such

that Io=Uo/R or Isc=Voc/R.

• The safety barrier must be CSA certified.

• Input voltage of the safety barrier must be less than 250 Vrms/Vdc.
