WARNING Only licensed experts may install electrical components. They must adhere to local and state legislation and regulations.
WARNING Make sure that you prepare or connect only de-energized wires.
WARNING The AC (mains) supply line must be equipped with an overcurrent protection device (a fuse or a circuit breaker). The current rating of the overcurrent protection device must be aligned with the cable size used to connect the PSU501. Unless local regulations state otherwise, use a maximum of 6 A device for 0.75 mm² (AWG 18) cables, a maximum of 10 A device for 1 mm² (AWG 17) cables and a maximum of 16 A device for 1.5 mm² (AWG 15) cables.

Do not replace the mains supply cord with a cord that has a lower rating than specified.

WARNING Keep away from live circuits. Operating personnel must observe safety regulations at all times.
WARNING Do not replace the battery with a battery of an incorrect type. If you do, there is a risk of explosion. Dispose of used batteries according to statutory regulations.
WARNING To avoid exposure to laser radiation, do not disassemble AQT530 unless instructed to do so in AQT530 maintenance instructions.
CAUTION EGW501 requires a separation distance of at least 20 cm (7.87 in). This distance must be maintained between the user and the device when the device is operating.
CAUTION Make sure that the grounding wire is longer than the phase and neutral wires. Under mechanical stress, the grounding wire must be the last to disconnect from the protective ground terminal.
To prevent electrostatic discharge, avoid touching component contacts or connectors.
