Installation Notes TMT86- CSA approved apparatus must be installed in accordance with manufacturer’s instructions.
- Install per Canadian Electrical Code or National Electrical Code (NFPA 70).
- Use supply wires suitable for 5°C above surroundings.
- Stating that only simple apparatus should be terminated to the sensor connection.

CSA approved Associated Apparatus
or Associated Nonincendive Field
Wiring Apparatus+-12412-WISE- The 2-WISE concept allows interconnection of intrinsically safe apparatus and associated apparatus
not specially assessed for such a combination. For the acceptance of the interconnection of thedifferent intrinsically safe circuits of these apparatus, the comparison of the voltage Ui (Vmax) withUo (Voc), the current Ii (Imax) with Io (Ioc), and the power Pi (Pmax) with Po (Pmax) of theinterconnected circuits must demonstrate that Ui (Vmax), Ii (Imax) and Pi (Pmax) are equal to or
greater than Uo (Voc), Io (Isc) and Po (Pmax) of the connected circuits.
In addition, the maximum internal capacitance (Ci) and maximum internal inductance (Li) of eachapparatus (other than those from auxiliary devices) connected to a 2-WISE system must not exceed
5 nF and 10 μH respectively.
- In a powered 2-WISE system only 2 ports (power source and power load) are allowed to beconnected at the opposite ends of a cable, with a maximum of two auxiliary devices connected in
between. The power source port supplies DC power to the system, and the power load port consumes
DC power from the system. Auxiliary device ports may also consume DC power from the system.
- The voltage Uo (Voc) of a power source port must be in the range of 14 to 17.5 V. Any other device
connected to the cable shall be passive, meaning that it is not allowed to provide energy to thesystem, with the exception of a leakage current of 1 mA for a power load port and a leakage currentof 50 μA for each auxiliary device port.
- The intrinsically safe circuit of a 2-WISE port shall be galvanically isolated from non-intrinsicallysafe circuits.
- The parameters of cable used to interconnect 2-WISE ports must be as follows:
Cable resistance Rc:
15 to 150 Ohm/km
Cable inductance Lc:
0.4 to 1 mH/kmCable capacitance Cc 1):
45 to 200 nF/km
Length of cable (not including cable stubs):£ 200 mLength of cable stubs:£1m- If the above rules are respected, the inductance and the capacitance of the cable will not impair theintrinsic safety of the installation.
