Installation & Usage Notes
- Voltage Matching: Ensure control voltage and load voltage align with module ratings (e.g., 24DC models for 24V DC control circuits)
- Pole Configuration: Select 3-pole (W3) for 3-phase circuits, 2+1 pole (W2+1) for mixed-phase loads, 1-pole (W1) for single-channel applications
- Safety Wiring: For H5-IES-SC models, follow SIL 3/PL e wiring guidelines (separate safety and standard wiring by ≥10mm)
- Current Limitation: Do not exceed maximum current ratings (e.g., 37A for W2+1 models); use contactors for loads beyond rated current
- Special Function Setup: For RDT models, connect diagnostic lines to the control system; for BR models, verify brake circuit compatibility
- Mounting Spacing: Reserve ≥5mm between modules for heat dissipation, especially for high-current (≥9A) variants
- Environmental Protection: Install in dry, dust-free control cabinets (IP20 protection); avoid direct exposure to moisture or corrosive substances
