Ship certification: LR (Lloyd's Register of Shipping), ABS (American Bureau of Shipping), suitable for ENV1-ENV4 Class 4 marine environment
Protection certification: Plastic shell IP66 (screw fixed) can withstand strong water spray, metal shell IP20 compatible for installation in cabinets
Safety regulations and precautions
Electrical safety: Protective grounding (PE) must be connected, with a wire diameter of ≥ 2.5mm ²; Insulation voltage lasts for 100Vac, test for 500Vac (1 second) to avoid leakage risk
Electrostatic protection: The equipment can withstand 85kV electrostatic spraying, but daily operation should avoid direct contact with PCB components; PCB replacement must be carried out in a voltage free environment, and both new and old boards require anti-static packaging protection
Wiring taboos: It is strictly prohibited to connect 100V and 400V voltage inputs simultaneously; CT secondary side cannot be open circuited, and voltage input cannot be short circuited; Separate wiring for different signal types (analog/digital) to reduce interference
Appendix Key Reference Information
CAN bus pin definition: Provides pin allocation for D-SUB DE9, RJ45/8P8C, and IDC interfaces, with CAN-H connected to 7-pin (D-SUB) and 1-pin (RJ45), and CAN-L connected to 2-pin (D-SUB) and 2-pin (RJ45) for easy interconnection of third-party devices
Wire diameter conversion table: including the correspondence between AWG and mm ² wire diameter (such as 14AWG=2.5mm ², 10AWG=6mm ²), for easy selection and matching
Compatible connectors: It is recommended to use narrow body D-SUB housings such as FCT (FKH1/FKC1G) and Wuerth Electronic (618009214622) to avoid interfaces that cannot be inserted
