4.1 Equipment Installation

The foundation, grounding system and cable duct should be prepared and incoming cables and outgoing cables and their protective pipes should be embedded before product installation. The product should be installed in accordance with relevant standards and specifications as well as the requirements of the equipment ventilation, cooling, installation and maintenance.

Transport the equipment to the installation site with a forklift, remove the bolts securing the base, take the equipment out of the box carefully, and prevent damages to the shell when removing the package;

This product can be installed in a dedicated foundation or concrete bench and should be placed horizontally. The product is secured onto the foundation with anchor bolts by passing through the bolt holes at the cabinet bottom. If the product is installed on the concrete foundation, it is recommended to adopt expansion bolts.

4.2 Inspection and Test before Putting into Operation

After the equipment is seated properly, open the front door of the cabinet, check the equipment and wiring in the cabinet, and note that all packaging materials must be removed from the box before power connection so as to avoid fire accident; check the insulators carefully for any damages, and contact the supplier immediately in case of damaged parts; check all electrical connection to confirm connection is secure and reliable; check whether all fixing bolts are tightened firmly.

Test before putting into operation: Measure insulation resistance; carry out power frequency voltage withstand test with the voltage not more than 85% of delivery test voltage in accordance with specified standards; remount the front panel and be ready for putting the equipment into service.


This equipment has high reliability and generally can be maintained without power cutoff. It is recommended to carry out inspection and maintenance strictly according to the safe operation procedure while the bus is being inspected and maintained with power cutoff.

Disconnect the equipment from the system;

Open the cabinet door and directly check the box inside for any abnormality;

Perform cleaning;

Confirm the insulation performance with a megger;

Check internal connection for reliability;

Check the bolts for tightness.
