Because the SEL-735 is often integrated into larger automation systems (DCS, BMS, SCADA), the manual provides specific register maps.

Installation and wiring instructions are foundational. The manual must include mounting dimensions, environmental ratings, power supply requirements, grounding recommendations, and detailed terminal diagrams. Clear wiring examples for current transformers (CTs), potential transformers (PTs), breaker trip and close circuits, and communications interfaces (Ethernet, serial, fiber) reduce installation errors and improve safety. Safety warnings and lockout/tagout procedures must be prominent and unambiguous to protect personnel during installation and maintenance.
