Why is a Work Permit Important for Height Work?
A Work at Height Permit is a formal document that:
Authorizes the specific high-risk activity.
Ensures all safety protocols are in place.
Protects workers, property, and the company legally.
Confirms that trained personnel are involved.
Minimizes the risk of injury or death.
How to Check Height Work (As a Facility In-Charge)
→ Use the HEIGHT SAFETY INSPECTION CHECKLIST before approving or monitoring any height-related activity:
1 Permit Verification
Is a valid Work at Height Permit issued?
Is it signed by the authorized personnel?
2 Competency Check
Are workers trained and certified for working at height?
Do they have valid harness & height safety training?
3 Risk Assessment
Has a risk assessment been done and reviewed?
Are emergency and rescue procedures identified?

FIMER 980-58-2173 inverter, a concise installation and commissioning guide can be created by summarizing information from official FIMER manuals for the PVS980-58 series. This guide is intended for qualified personnel only.
ReplyDeleteThis is a summary and not a substitute for the official manufacturer's manual. Always follow the full, detailed, and model-specific documentation provided by FIMER.
Safety precautions
Qualified personnel only: Only FIMER-trained and certified electricians should perform these procedures.
Disconnect power: Always disconnect all possible power sources—including the solar array and AC grid—before beginning work.
Lockout/Tagout: Lock disconnectors in the open position and attach warning notices to prevent accidental reconnection.
Wait to discharge: After disconnecting, wait at least 5 to 10 minutes for internal capacitors to discharge before proceeding.
Verify zero voltage: Use a multimeter or a suitable voltage tester to confirm there is no voltage on the AC and DC terminals.
Wear PPE: Use appropriate personal protective equipment.
Installation procedure
1. Mechanical installation
Prepare the site: Ensure the mounting area meets the inverter's space and ventilation requirements, and that the foundation is level and can support the inverter's weight.
Move the inverter: Use appropriate lifting equipment to move the unit into position.
Mount the inverter: Securely bolt the inverter to the prepared foundation.
2. Electrical installation
Auxiliary power connection:
Connect the external auxiliary power supply cable to the designated terminals.
Set the inverter's auxiliary power switch to the "off" position during wiring.
DC cable connections:
Check the correct polarity and voltage of all incoming DC strings using a multimeter.
Connect the positive and negative DC cables from the solar array to the correct inverter terminals.
Ensure all DC connections are tight and securely sealed.
AC cable connections:
Connect the three-phase AC output cables and the grounding cable to the appropriate terminals.
Ensure the AC output cable connections are tight and the gland plates are properly sealed to maintain the inverter's IP rating.
To find the most accurate and safe installation and commissioning procedure for the FIMER 980-58-2173 inverter, it is recommended to consult the official FIMER manuals specifically for the PVS980-58 series. These documents provide detailed, step-by-step instructions and critical safety information tailored to the specific model.
Accessing and carefully following the manufacturer's complete documentation is essential for ensuring correct installation, safe operation, and compliance with all relevant standards and regulations. Always prioritize the full manual provided by FIMER over any summarized guide.
These procedures should only be performed by qualified and FIMER-trained personnel who are familiar with working with high-voltage electrical equipment and solar inverter systems. Always adhere to safety precautions, including disconnecting all power sources, verifying zero voltage, and wearing appropriate personal protective equipment
