Page 19: Description
LKP Series 3. DESCRIPTION OVERVIEW The DynAmp, LLC LKP-100 is a 10 channel metering system for accurately measuring direct current in a bus up to 100 kA. The system consists of a Measuring Head, a Metering Unit, and two multi-conductor cables. - Page 20 5.) A normally closed relay contact for accuracy diagnostics output. This feature is only available when the accuracy diagnostics option is ordered. 6.) Optional isolated shunt output. Scaling is per customer order: 0-10V, 4-20mA available. © 2016 DynAmp, LLC Page 6 041738 I...

Page 25: Installation Precautions (Live Bus)
Warning : Keep all exposed head cable leads from touching the bus, ground, or any support structures. Consult with DynAmp about using a shorting plug at each connector. INSTALLATION PRECAUTIONS (LIVE BUS) If the unit is to be installed on a live bus, the following precautionary measures must be taken before installing the Measuring Head: A.) Make sure that the cables are disconnected from the head during installation. -
