Special conditions for intended use

1. For use with Listed current transformers suitably rated for the application only, terminals EL3453 and EL3783 may also measure the current directly.
2. Connected wires must be rated min. 75°C, 300 V or 600 V (depends on rated voltage of EtherCAT Terminal) and be made of copper.
3. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
4. Pollution degree 2.
5. Requirements related to the external current transformers as per annex DVE of UL/CSA 61010-1:
  1. WARNING To reduce risk of electric shock, always open or disconnect circuit from power-distribution system (or service) of building before installing or servicing current transformers or equivalent.
  2. Per DVE.3.2.1:
    • Always open or disconnect circuit from power-distribution system (or service) of building before installing or servicing current transformers.
    • The current transformers may not be installed in equipment where they exceed 75 percent of the wiring space of any cross-sectional area within the equipment.
    • Restrict installation of current transformer in an area where it would block ventilation openings.
    • Restrict installation of current transformer in an area of breaker arc venting.
    • Not suitable for Class 2 wiring methods and not intended for connection to Class 2 equipment.
    • Secure current transformer and route conductors so that the conductors do not directly contact live terminals or bus.
