- Only qualified electrical workers should install this equipment. Such work should be performed only after reading this entire set of instructions.
- NEVER work alone.
- Before performing visual inspections, tests, or maintenance on this equipment, disconnect all sources of electric power. Assume that all circuits are live until they have been completely de-energized, tested, and tagged. Pay particular attention to the design of the power system. Consider all sources of power, including the possibility of back feeding.
- Turn off all power supplying the voltmeter and the equipment in which it is installed before working on it.
- Always use a properly rated voltage-sensing device to confirm that all power is off.
- Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. In the USA, see NFPA 70E
- Before closing all covers and doors, carefully inspect the work area for tools and objects that may have been left inside the equipment.
- Use caution while removing or installing panels so that they do not extend into the energized bus; avoid handling the panels, which could cause personal injury.
- The successful operation of this equipment depends upon proper handling, installation, and operation. Neglecting fundamental installation requirements may lead to a personal injury as well as damage to electrical equipment or other property.
- The power meter should be installed in a suitable electrical and fire enclosure.
...
The transducer and the transceiver are installed together.
- Mount the transducer using M4 screws and M4 nuts. The distance between mounting holes is 50 mm.
- Mount the current transceiver using M4 screws and M4 nuts. The distance between mounting holes is 60 mm.
- Use a 4-core flat cable and two green connectors supplied with the transceiver and the transducer to assemble the connecting cable.

Potential Problem | Possible Cause | Possible Solution |
---|---|---|
The data being displayed is inaccurate or not what you expect. | Incorrect setup values. | Check that You use the correct f(x) formula |
Incorrect voltage inputs. | Check power meter voltage input terminals to verify that adequate voltage is present | |
The power meter is wired improperly. | Check that all wires are connected correctly and that they are energized. See “Wiring Diagrams” of the device. | |
The sensor does not appear in the Vutlan monitoring interface | Communications lines are improperly connected. | Check the 6P4C RJ11 communication cable. |
The communication cable is inserted into the wrong port. | 6P4C RJ11 communication cable must be inserted into the analog port of the Vutlan monitoring system. |
