Installation Guidelines

• Thermal Management: Mount the unit in a well-ventilated enclosure where ambient cabinet temperatures remain within the certified -10 degC to +60 degC operating range.
• Wiring Protocols: Use appropriately rated heavy-gauge copper wiring to accommodate current loads up to 100A and prevent localized terminal overheating.
• Power Isolation: Ensure all main incoming line voltages (380-480V) are completely isolated and locked out prior to mounting or servicing the circuit assembly.
