Notes
1) In the
USA
: The installation must be in accordance with the National Electrical Code
®
, NFPA 70, Article 504 or
505 and ANSI / ISA-RP 12.6.
In Canada : The installation must be in accordance with the Canadian Electrical Code
®
, Part1, Section 18.
2) The apparatus must not be connected to any device that uses or generates in excess of 250Vrms or DC.
U
m
= 250V.
3) In the USA : The Apparatus must be connected to a suitable ground electrode per National Electrical Code
®
,
NFPA 70, Article 504 or 505. 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.
4) Connection by non interchangeable cable type LiYC-Y-CY 4 x 0.5; max length: 50m (164 ft).
5) Connection by means of polarized connector outside of the indicator.
6) Connection by non interchangeable cable type LiYC-Y-CY 4 x 0.5; max length: 0.5m (1.6 ft).
7) The cable must be protected against damage.
8) The circuits of the data output interface shall be assumed to be connected to earth.
9) The cable needs not be protected against damage.
10) Equipment with metallic housing (IP4x in minimum) and passive wiring, only. For use in Class II,III, Division 1
and in Zone 21 the housing must be IP6x.
11) The cable to the T-Connector must be protected against damage.
12) Any NRTL approved equipment with Entity Concept parameters (see note 13)
13) 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 Voc, Isc and Pmax resp. Uo, Io,
Po of the associated apparatus are less than or equal to Vmax, Imax and Pmax resp. Ui, Ii, Pi of the intrinsically
safe apparatus and the approved values of Ca and La resp. Co and Lo of the associated apparatus are greater
than Ci and Li of the intrinsically safe apparatus plus all cable parameters.
For the input and output parameters of the data interrface of the SIWXS...-3-..-… / ISX…-..-… see page 2.

18) The Sartorius Power Supply Model YPS02-XKR is /certified by CSA for use in Canada. See Certificate of
Compliance and Control Drawing number 65516-000-17.
19) The Sartorius Power Supply Model YPS02-XUR is approved by FM for use in the USA. See Certificate of
Compliance and Control Drawing number 65516-000-17.
20) The Sartorius Indicator Series CAIXS2-.... is approved/certified by FM for use in the USA and in Canada. See
Certificate of Compliance and Control Drawing number 66015-751-07.
21) Ambient temperature range: -10°C .... +40°C (14°F .... +104°F) The temperature class for gases of the
SIWXS... / ISX… is T4. The maximum surface temperature for dusts of the SIWXS... / ISX… is 80°C (176°F).
22) WARNING: SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.
