Safety Warning Signs; Emergency Escape Route; Pv Arrays Hazards; Live Line Measurement - Sungrow SG500MX Operation Manual

2 Safety Instructions
 All safety instructions, warning labels and nameplate on the inverter body must be
clearly visible;
 Replace the markings once they are damaged or unclear.

2.3.4 Safety Warning Signs

Please respect the followings during installation, daily maintenance or troubleshooting of the
inverter:

An obvious marking should be placed in the inverter upstream and downstream to keep the
switch from accidental reconnection;

A temporary warning sign or barrier must be posted around the installation area;

Remove the door keys and keep them appropriately after installation or maintenance work
is finished.

2.3.5 Emergency Escape Route

The emergency escape route is critical during an emergency situation.

Keep the escape route clear and unblocked at all times.

Never block or lock the emergency escape route

2.3.6 PV Arrays Hazards

High Voltages will exist between positive and negative polarities immediately when the PV
arrays are exposed to light. Electrical shock or arc may occur by accidental touch.
High voltage exists between the positive and negative polarity of the PV array.
 Ensure complete disconnection between the inverter and the PV array
 Avoid any accidental reconnections.

2.3.7 Live Line Measurement

High voltages are present in the device. Death resulting from burning and electric
shock upon touching the live components of the inverter. During live line
measurement,
 use suitable protective equipment , for example dielectric gloves, and
 accompany by other persons.

2.3.8 Measuring Instrument

Instrument for measurement of the electrical parameters should meet the requirements listed
