Important Information
To ensure reliable, long-term operation of this Integrated Rectifier Technologies Inc. Cathodic Protection Rectifier and the safety of personnel, please follow these Installation and Safety guidelines.
WARNING – RISK OF ELECTRICAL SHOCK
As hazardous voltages are present within this rectifier unit, installation and maintenance must be restricted to qualified electronic or electrical personnel only. Failure to correctly install or service this rectifier may expose personnel to dangerous voltages or other hazards that may result in injury as well as cause damage to the rectifier and other equipment.
Refer to the Installation, Operation, & Maintenance Manual for additional details.
Delivery Inspection
Always thoroughly inspect the rectifier upon receipt, both externally and internally, for any signs of shipping damage. Do not install or energize a rectifier that has been damaged.
Do’s
- Familiarize yourself with any possible hazard points within the rectifier unit by reviewing the electrical schematic and the physical layout of the rectifier prior to any maintenance.
- Set the AC utility disconnect to the “OFF” position prior to servicing the rectifier unit.
- Tag and lock out the disconnect to ensure others do not energize power while you are servicing the rectifier unit.
- Inspect and tighten any connections on the rectifier that may have become loose during shipment.
- Make sure that the wall, pole, frame, or mounting pad is designed to hold the full weight of the rectifier.
- Install the rectifier so as not to obstruct any of the enclosure venting and to allow for proper cooling.
- For oil-cooled types, ensure to fill the oil compartment to the fill line with suitable insulating oil.
- Ensure that the available AC voltage is suitable for the rectifier, that the AC input wiring is connected to the correct terminals, and that the rectifier input is properly configured for the AC voltage available.
- Supply the rectifier with a proper ground connection.
- Connect the cable(s) from the anode bed to the rectifier DC positive terminal(s) and the cable(s) from the structure to the rectifier DC negative terminal(s).
- Prior to energizing the rectifier, make sure that the rectifier is at its lowest output setting. For three-phase rectifiers, always set the secondary taps equally for all phases.
Don’ts
- Energize the rectifier if you are NOT 100% sure of the above steps.
- Start the rectifier at any tap or control setting other than minimum.
- Overload the rectifier under any circumstances.
- Mount any additional equipment within the rectifier without prior approval from the factory.
