Length Length Width Height DZ81-MS3E5C 3.2 Installation Method This series of products should be installed in a dry and dust free environment, and avoid exposing to excessive heat, radiation and high electrical noise source. The meters can be installed into a standard panel cutout of switch cabinet. -
Page 7: Chapter 5 Typical Wiring
Chapter 5 Typical Wiring 5.1 3-phase 4-wire Wiring Mode (3LN, 3CT) The star-like 3-Phase 4-Line wiring mode is commonly used in low-voltage electric distribution power systems. The “UL” (voltage wiring mode) on the parameter setting interface should be set as “3Ln”; “IL” (current wiring mode) should be set as “3C”. 5.2 Three-Phase Three-Line Open Delta Mode (2LL, 2CT) -
