This device is marked with the international Caution symbol. It is important
to read this manual before installing or commissioning this device as
it contains important information relating to Safety and EMC (Electromagnetic
Compatibility).Unpacking & Inspection NOTE: Unpack the instrument and inspect for obvious shipping damage. Do not attempt to operate the unit if damage is found. This instrument is a panel mount device protected in accordance with Class I of EN 61010 (115/230 AC power connections). Installation of this instrument should be done by Qualified personnel. In order to ensure safe operation, the following instructions should be followed. This instrument has no power-on switch. An external switch or circuit-breaker shall be included in the building installation as a disconnecting device. It shall be marked to indicate this function, and it shall be in close proximity to the equipment within easy reach of the operator. The switch or circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it shall meet the relevant requirements of IECá947û1 and IEC 947-3 (International Electrotechnical Commission). The switch shall not be incorporated in the mains supply cord. Furthermore, to provide protection against excessive energy being drawn from the mains supply in case of a fault in the equipment, an overcurrent protection device shall be installed.
The Protective Conductor must be connected for safety reasons. Check that
the power cable has the proper Earth wire, and it is properly connected.
It is not safe to operate this unit without the Protective Conductor Terminal
connected.
ò Always disconnect power before changing signal and power connections. ò Do not use this instrument on a work bench without its case for safety reasons. ò Do not operate this instrument in flammable or explosive atmospheres. ò Do not expose this instrument to rain or moisture. EMC Considerations ò Whenever EMC is an issue, always use shielded cables. ò Never run signal and power wires in the same conduit. ò Use signal wire connections with twisted-pair cables. ò Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems persist. Disconnect all signal input and outputs before attempting this procedure. Instructions 1. Open the Signal Conditioner UnitùRemove Side Covers from Unit by lifting at the ôangled cornersö first, using a flat-head screwdriver. Continue detaching remaining edges of the Cover. 2. Short TP6 & TP17 together, either by wire or, if available, jumper S1-A. 3. After shorting TP6 to TP17, apply power to the unit. 4. The Front Panel Power Indicator (LED) will NOT turn on. 5. After power has been applied to the unit for about 30 seconds, turn power off. 6. The communication parameters now have been restored to the default settings. 7. Use the DRX Set-up Program to establish communication with the meter. 8. This procedure will not affect calibration. It only resets the communication parameters. |
