Specific Conditions of Use (Special Conditions)
The following conditions relate to the safe installation and/ or use of the
equipment.
a. When the transmitter is installed in a Zone 0 hazardous area ignition
sources due to impact and friction sparks could occur. The user must
ensure protection of transmitter against impact or friction.
b. The flameproof joints shall not be repaired. Contact the manufacturer
for information on the dimensions of the flameproof joints.
c. The Intrinsically Safe version of the transmitter does not satisfy 500 V
test per IEC 60079-11, Clause 6.3.1.3 and shall be supplied by an
isolated barrier which is suitable with the electrical parameters of the
equipment: Ui = 28 V, Ii = 93 mA, Pi= 0.65 W, Li = 0 mH, Ci = 0 μF.
d. The user shall ensure the surface temperature of the sensor connector
does not exceed +60 °C (+140 °F).
Conditions of Acceptability:
a. Temperature code depends on process temperature as follows:
T-Code
Ambient Temperature
Process Temperature
Gas, Vapor & Mists
T6
-40 to 60 °C
-40 to 80 °C
Dusts, Fibers & Flyings
T80°C
-40 to 60 °C
-40 to 80 °C
b. The branch pointing and entry point temperature may exceed 60 °C when
the process temperature is more than 80 °C. If this occurs, the end user
shall select the suitable certified cable, conduit fittings and stopping plug
for final installation. Use conductors rated at least 5 °C above the
maximum operating ambient.
c. Wiring to or from this equipment, which enters or leaves the explosion-
proof enclosure, must utilize wiring methods suitable for Class I, Division 1
Hazardous Locations in accordance to the Canadian Electrical Code or
National Electrical Code.
d. This equipment may only be powered by a power supply unit with a
limited energy electric circuit in accordance with CAN/CSA C22.2 No.
61010-1-12 and ANSI/UL 61010-1, or Class 2 as defined in the Canadian
