LERBAKKEN 10, 8410 RØNDE DENMARK
Installation notes 9107Ax and 9107Bx:
The module must be installed in a tool-secured enclosure suitable for the application in accordance with the
National Electrical Code (ANSI/NFPA 70) for installation in the United States, the Canadian Electrical Code
for installations in Canada, or other local codes, as applicable.
The module is galvanically isolated and does not require grounding.
Terminal 41, 42, 43, 44 are internally connected to CH1.
Terminal 51, 52, 53, 54 are internally connected to CH2.
Install in pollution degree 2, overvoltage category II in accordance with IEC 60664-1.
Use minimum 75 ºC copper conductors with wire size AWG: (26-14)
Warning: Substitution of components may impair intrinsic safety.
Avertissement : La substitution des composants peut nuire à la sécurité intrinsèque.
There are no serviceable parts in the equipment and no component substitution is permitted.
Warning: To prevent ignition of the explosive atmospheres, disconnect power before servicing and do not
separate connectors, install or remove module from Power Rail when energized and an explosive gas
mixture is present.
Avertissement : Pour éviter l'inflammation d'atmosphères explosibles, déconnectez l'alimentation avant les
opérations d'entretien. Ne montez pas ou n'enlevez pas les connecteurs quand le module est sous tension
et en présence d'un mélange de gaz. Ne montez pas ou n'enlevez pas les modules du rail d'alimentation en
présence d'un mélange de gaz.
Installation notes 9107Bxx:
Associated Equipment /Appareillage Associé [Ex ia]
The Ex output current of this associated apparatus is limited by a resistor such that the output voltage-
current plot is a straight line drawn between open-circuit voltage and short-circuit current.
Selected intrinsically safe equipment must be third party listed as intrinsically safe for the application, and
have intrinsically safe entity parameters conforming withTable 1 below.
TABLE 1:
I.S. Equipment
V max (or Ui) ≥
I max (or Ii) ≥
P max, Pi ≥
Ci + Ccable ≤
Li + Lcable ≤
The module may also be connected to a simple apparatus as defined in Article 504.2
and installed and temperature classified in accordance with Article 504.10(D) of the National Electrical
Code (ANSI/NFPA 70), or other local codes, as applicable.
Capacitance and inductance of the field wiring from the intrinsically safe equipment to the associated
apparatus shall be calculated and must be included in the system calculations as shown in Table 1. Cable
capacitance, Ccable, plus intrinsically safe equipment capacitance, Ci must be less than the marked
