Ci = 11 nF (+0.3 nF/m with cable), Li = 10 µH (+2 µH/m with cable)
Notes
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 ≤ V
Po ≤ Pi
2. For this current controlled circuit, the parameter I
non-incendive field wiring apparatus.
3. Installation shall be in accordance with the National Electrical Code
4. The configuration of Control Equipment must be under non-incendive field wiring concept and FM Approved.
5. Control Equipment manufacturer´s installation drawing must be followed when installing this equipment.
6. No revision to this drawing without prior approval by FM.
