How to Install the QC75PEKB Transformer

This guide provides step-by-step instructions for the installation and initial setup of the QC75PEKB transformer, ensuring safe and proper operation.

Estimated time: 1h

Tools needed:

Screwdriver, Drill, Multimeter

Supplies needed:

Mounting screws, Lock washers, Flat washers, Rubber washers

  1. Select the installation location

    Choose a non-combustible surface that allows for adequate air circulation around the transformer. Ensure the location is dry and free from contaminants.

  2. Mount the transformer

    Using the provided mounting template, drill the top two mounting holes. Lift the transformer into position and secure it with the top mounting bolts. Level the unit and mark the lower mounting holes, then install the lower mounting bolts with lock washers, flat washers, and rubber washers.

  3. Connect the wiring

    Loosen the cover screw on the wiring compartment to access the terminals. Connect the input and output cables according to the nameplate diagram, ensuring all connections are tight and insulated. Use electrical joint compounds on all connections.

  4. Ground the transformer

    Ensure the transformer is properly grounded according to local codes. Verify that all ground connections are secure before energizing the transformer.

  5. Perform pre-energization checks

    Before energizing, check the insulation resistance to ensure it is greater than 10MΩ. Verify that the output voltage matches the nameplate specifications and that all connections are tight.
