How to Install the DAHHL300AC Heater

This guide provides step-by-step instructions for installing and wiring the DAHHL300AC heater in hazardous locations.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors

  1. Mount the heater

    Secure the heater to the unistrut using the four M6 bolts provided in the mounting kit. Ensure the fins are positioned vertically for effective convection.

  2. Connect the wiring

    Install the connection cable into the customer-supplied junction box, ensuring to observe the permissible bending radius of 5 times the outside cable diameter. Use a cable gland or ½ NPT conduit as required.

  3. Ground the heater

    Connect the ground terminal to ensure potential equalization. Use a suitable circuit breaker for protection, and ensure compliance with local electrical codes.

  4. Power on the heater

    Once all connections are secure, turn on the heater. Be aware that the startup current may be 3 to 5 times greater than the nominal current for the first few seconds.

  5. Verify operation

    Use a multimeter to check the voltage and current to ensure they are within the specified limits. Monitor the heater for proper operation.
