Notes
1) In the USA: The installation must be in accordance with the National Electrical Code
ANSI / ISA-RP 12.06.01.
In Canada: The installation must be in accordance with the Canadian Electrical Code
2) The apparatus must not be connected to any device that uses or generates in excess of 250Vrms or DC.
U = 250V.
m
3) In the USA: The Apparatus must be connected to a suitable ground electrode per National Electrical Code
NFPA 70, Article 504. The resistance of the ground pad must be less than 1 ohm.
In Canada: The Apparatus must be connected to a suitable ground electrode per Canadian Electrical Code
Part 1. The resistance of the ground pad must be less than 1 ohm.
The load cell ground (housing) must be insulated from the surface on which it is mounted or be at the same
potential of the NRTL approved apparatus ground as per installation drawings.

apparatus.
5) The Entity Concept allows interconnection of intrinsically safe apparatus with associated apparatus not
specifically examined in combination as a system when the approved values of Vo and Io of the associated
apparatus are less than or equal to Vi and Ii of the intrinsically safe apparatus and the approved values of Co
and Lo of the associated apparatus are greater than Ci and Li of the intrinsically safe apparatus plus all cable
parameters.
7) Ambient temperature range:
-40°C .... +55°C (-40°F .... +131°F) for T5 and -40°C .... +70°C (-40°F .... +158°F) for T4A.
