1-2 Product Description
1403-IN001A-US-P
Quick Start - Minimum Device Configuration
At a minimum, the following steps MUST be
followed for proper operation of your Powermonitor
II. Any other device configuration options are only
required for operation of additional functions of the
Powermonitor II.
1. Configure the PT and CT ratios to match your
system. Remember, for systems with greater than
120 volts applied to the voltage inputs, the PT
secondary must be configured to greater than 137
volts to switch to high voltage mode. For
example: a 600 V
L-L
(347 V
L-N
) direct-connect
system is configured with a PT ratio of 347:347.
2. Configure the Voltage Mode to match your system
wiring. Use the wiring diagrams in Chapter 2,
Figure 2.2 through Figure 2.13 to select the
appropriate mode.
Measurements
The Powermonitor II provides numerous display
measurements and programming characteristics.
Note: Update rates and accuracy are listed in
Appendix C, Technical Specifications
Displays
The Powermonitor II Master Module communicates
to the Display Module over a fiber optic serial
communications link. Up to three Display Modules
can connect to one Master Module.
