Certificate: 70009819
Project: 80065116
Conditions of Acceptability:
1) The probe must not be installed in zone 0 or zone 20.
2) The interface circuit RS485 serves exclusively for intercommunication of the probes and must not be
connected to an external RS485 circuit.
3) Repair of flameproof joints is not permitted. If repair is required, the equipment shall be returned to the
manufacturer.
4) For 24Vdc models: 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 Electrical Code C22.1, Section 16-200 and/or National Electrical Code (NFPA
70), article 725.121.
