MAJORSINE Inverter Manual / M101.4 2. IMPORTANT SAFETY INSTRUCTIONS 2-1 Safety Statement SAVE THESE INSTRUCTIONS - This manual contains important inverter instructions that should be followed during installation and maintenance of the MAJORSINE inverter unit. To reduce the risk of electric shock, install the inverter in a temperature and humidity controlled indoor environment, free of conductive contaminants. Ambient temperature should not exceed 50oC (122oF).
MAJORSINE Inverter Manual / M101.4 Reduced air flow: Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Mechanical loading: Mounting of the inverter in a rack should be level and balanced. Wiring: Adequate input power must be supplied to the inverter for proper use; correct wiring sizes must be respected. Grounding: Reliable grounding of rack-mounted equipment should be maintained.
