PM172 Quick Start Guide Electrical Installation IMPORTANT! Only qualified personnel can perform setup. All incoming power sources must be turned off during installation. During operation of the Powermeter, hazardous voltages are present on the input terminals. Failure to observe precautions can result in serious or even fatal injury, or damage to equipment. Refer to the installation and operation manual for further information.
PM172 Quick Start Guide Figure 7: Typical Installation 1 The typical installation diagram above shows a 4-Wire Wye 3-element connection using 3 PTs and 3 CTs. The wiring mode is 4LL3 or 4Ln3.
PM172 Quick Start Guide The typical installation diagram above shows a 4-Wire Wye 2½-element connection using 2 PTs and 3 CTs. The wiring mode is 3LL3 or 3Ln3. The voltages must be balanced for the configuration to provide accurate power measurements. There are approximately nine different wiring configurations in the PM17X Series. Refer to the Installation and Operational Manual for additional configurations. For electrical installation of the display panel follow the following steps: 1.
PM172 Quick Start Guide Setup is performed directly from the display panel or via the communication ports using PAS communication software. In Data Display mode, the navigation buttons function as follows. The MIN/MAX button switches to the Min/Max Maximum Demands display pages. When briefly pressed again, it switches back to the common measurements display. The TDD/THD/ESC button switches between different total harmonics (THD/TDD) displays.
