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.
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) The cable to the terminal model YAC01LA-X00FC and to the T-Connector model YTE02-X must be protected
against damage.
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 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.
6) In the USA: Optionally, the cable of any FMRC Approved Universal Apparatus with Entity Concept parameters (see
note 5) can be connected directly to the data output of the weighing module; this cable must be protected against
damage.
In Canada: Optionally, the cable of any CSA Certified Universal Apparatus with Entity Concept parameters (see
note 5) can be connected directly to the data output of the weighing module; this cable must be protected against
damage.
7) The apparatus must not be connected to any device that uses or generates in excess of 132Vrms or DC.
8) The cable to the terminal model YAC01FC-X or model YAC02FC-X needs not be protected against damage.
9) In the USA: These units are considered as non-certified simple apparatus. The levels as indicated for simple
apparatus in FMRC Class 3610 shall not be exceeded in this simple apparatus.
In Canada: These units are considered as non-certified simple apparatus. The temperature class of the apparatus
has to be determined. Per Levels generated in the simple apparatus as indicated in Table 3 of CAN/CSA-E79-11-
95.
When the parameters of the apparatus are not specified, based on the entity parameters of the weighing module
output the temperature class has to be determined and the capacitance and inductance of the interconnecting cable
may not exceed the Co and the Lo.
10) Connection by means of polarized connector.
11) Ambient temperature range: 0°C .... +40°C (32°F .... + 104°F)
12) WARNING:
AVERTISSEMENT:
13) Connection by non interchangeable cable type LiYC-Y-CY 4 x 0.5; max length: 50m (164 ft).
14) 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.
The output circuits of the optional I/O of Type FCB must be connected to grounded shunt diode barriers; this ground
to be connected with the P.E. within the hazardous area.
15) The Minebea Interface Converter YDI05-Z.. is approved/certified by FM for USA and Canada. See Certificate of
Compliance and Control Drawing number 65710-800-07-A4.
Furthermore Minebea Barriers YDI01-Z.. and YDI02-Z.. may be used, which contain FM and CSA approved /
certified Z966 zener barriers from Pepperl & Fuchs.
16) WARNING: USE WET OR DAMP CLOTH TO CLEAN TO AVOID ELECTRIC STATIC DISCHARGE.
