1. The non-incendive field wiring concept allows the interconnection of two devices with non-incendive parameters not specifically examined in combination as a system when:

Uo or Voc ≤ Vmax, Io or Isc ≤ Imax, Ca or Co ≥ Ci + Ccable, La or Lo ≥ Li + Lcable, Po ≤ Pi.

2. Dust-tight conduit seal must be used when installed in Class II and Class III environments.

3. Control equipment connected to the Associated Apparatus must not use or generate more than 250 Vrms or Vdc.

4. Installation should be in accordance with the Canadian Electrical Code (CEC) Part I for Canada or the National Electrical Code

5. The configuration of Associated Apparatus must be under entity or non-incendive field wiring concept and - for the USA - FM Approved.

6. Associated Apparatus manufacturer`s installation drawing must be followed when installing this equipment.

7. Special Condition of use: Potential Electrostatic Charging Hazard - Parts of the enclosure may be constructed from plastic. To prevent the risk of electrostatic sparking the plastic

surface should be cleaned only with a damp cloth.
