WARNING!
In hazardous locations all installations must only be carried out by qualified personnel!
Switch off all power supplies before installing or uninstalling the unit in hazardous locations!
3.3.1 Locating the Compact Version
The TCM***-**-****-E*** -Ex is explosion proof with EX d for the electronics and Ex i for the meter.
The inputs and outputs are not power limited and must not be used to drive intrinsically save circuits
WARNING!
Never open any cover of the electronics in hazardous locations with any supply or I/O circuits alive!
3.3.2 Locating the Remote Version with TCE80**-E-****-Ex
NOTE
For use in hazardous locations the TCM as well as the TCE must be Ex versions!
The TCM***-**-****-****-Ex is intrinsically safe when driven by the corresponding TCE80xx-Ex.
The TCE80**-E-****-Ex is explosion proof “EX d”. It contains the safety barriers for the TCM.
The inputs and outputs of the TCE are not power limited and must not be used to drive intrinsically save circuits
The TCE80**-E-****-Ex can be located inside and outside the hazardous area.
WARNING!
Never open any cover of the TCE80**-W-****-Ex in hazardous locations with any supply or I/O circuits
alive!
3.3.3 Locating the Remote Version with TCE80**-L-****-Ex
NOTE
For use in hazardous locations the TCM as well as the TCE must be Ex versions!
The TCM***-**-****-****-Ex is intrinsically safe when driven by the corresponding TCE80xx-Ex.
The TCE80**-L-****-Ex is not explosion proof and only provides the intrinsically safe connections to the TCM.
The inputs and outputs of the TCE are not power limited and must not be used to drive intrinsically save circuits
The TCE80**-L-****-Ex must be located outside the hazardous area.
3.3.4 Electrical connections
Compact and Wall Mount Version
The supply terminals and the digital I/O terminals are rated for U
M
= 250V whereas the analog output and
interface terminals are rated for U
M
= 30V DC.
For making the required connections proceed as follows:
Prepare the cable and the TCE as described in chapter 3.2.
