Structural features:
This type of transformer is epoxy resin casting fully closed structure, with excellent insulation properties and moisture resistance. Compact structure, small volume, light weight and easy surface cleaning. The secondary wiring is equipped with a junction box, and there are four mounting holes on the bottom plate for installation.
Installation and Maintenance.
Installation and maintenance:
The transformer arrives at the use of units need to check the packing list should be attached to the packing box, product certification, instruction manual and factory certificate of conformity. The structure of the product has no defects or damage caused by transportation or other reasons. The grounding bolt should be properly grounded before the transformer is used. During operation, the secondary winding must be reliably connected to the load, and the unused secondary winding must be shorted to the secondary outlet terminal.
The secondary winding must be connected to the load reliably during operation.
