SECTION 3
When installed in Zone 2 locations:
The THZ3 Temperature Transmitter shall be mounted within a tool-secured enclosure which
meets the requirements of ANSI/ISA-60079-0, ANSI/ISA-60079-15 and ANSI/ISA 61010-1 or
CAN/CSA-C22.2 No. 60079-0, CAN/CSA-C22.2 No. 60079-15 and CAN/CSA-C22.2
No. 61010-1 and is capable of accepting the applicable wiring methods wiring methods per
the NEC or the Canadian Electrical Code. The enclosure shall, at a minimum, meet the
requirements of IP54.
The non-metallic parts incorporated in the THZ3 DIN mount housing may generate an
ignition-capable level of electrostatic charge. The equipment shall not be installed in a location
where the external conditions are conducive to the build-up of electrostatic charge on such
surfaces. Additionally, the equipment shall only be cleaned with a damp cloth.
The THZ3 shall be provided with supply transient protection external to the apparatus such that
the voltage at the supply terminals does not exceed 119Vac peak or 119Vdc.
