Use no-voltage inputs for the event inputs.
The polarity for non-contact inputs is given in parentheses.
Note: 1. The application of the terminals depends on the model.
2. Do not wire the terminals that are shown with a gray background.
3. When complying with EMC standards, the cable that connects the sensor must be 30 m or less. If the cable length exceeds 30m,
compliance with EMC standards will not be possible.
4. Connect M3 crimped terminals.
5. Due to UL Listing requirements, use the E54-CT1L or E54-CT3L Current Transformer with the factory wiring (internal wiring).
Use a UL category XOBA or XOBA7 current transformer that is UL Listed for field wiring (external wiring) and not the factory wiring
(internal wiring).

Note: Auxiliary outputs 1 to 2 are not insulated.
The E5DC is set for a K-type thermocouple (input type = 5) by default.
An input error (s.err) will occur if the input type setting does not agree
with the temperature sensor. Check the input type.
