Chapter 1 PowerMonitor 1000 Overview
Functionality by Model
The power monitor models differ by the data sets available to client applications.
This table indicates the measurements and functions available in each model.
7. Voltage-
sensing wiring terminals
• Direct connect up to 600V AC three-phase line-to-line
• Maximum nominal line-to-ground voltage 347V
• Use potential transformers (PTs) for higher voltages
8. Current-
sensing wiring terminals
• Nominal input current 5 A
• Use current transformers (CTs) to connect to power system
9. DIN-rail clips • Top and bottom clips for mounting unit on DIN rail
10.Status-input wiring
terminals
• Two internally-powered inputs
• S2 can be used for demand period synchronization
11.Configuration-
lock wiring terminals
• Wire together to prevent configuration changes
12.KYZ-output wiring
terminals
• DPDT solid-state relay for signaling use
13.Control power and ground
wiring terminals
• 120…240V AC, 50…60 Hz
