The secondary wiring is equipped with a junction box, and there are four mounting holes on the bottom plate for installation.
The product has 4 mounting holes on the base plate for installation.
Installation, use and maintenance:
The transformer arrives at the use of units need to do the following checks: packing list should be attached to the packing box, product certification, instruction manuals and factory certificate of conformity. Product specifications should meet the requirements. The product structure has no defects or damage caused by transportation or other reasons.
The product structure has no defects or damages 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 secondary winding not in use must be shorted to the secondary outlet terminal.
