Plug-In Type Units INSPECTION Prior to installation we recommend the following: Check the nameplate to verify that the unit received matches the rating specified in your order. Verify that the line frequency, current and voltage rating are suitable for your application. Inspect the unit for visible signs of shipping damage.
MAINTENANCE No regular maintenance is required on Staco Energy Products Co. Variable Transformers as long as the ratings of the unit are not exceeded. Normally, the brush may be expected to last the life of the unit. Occasionally, brushes may need replacement. Should this become necessary, it is essential that a new or reinstalled brush be properly seated.
