DANGER
Make sure that the seal is correctly positioned and seated when the cover is fitted back on. The
IP54 protection degree of the casing will be impaired if the seal is positioned incorrectly.
DANGER
Take care of the ground connection soldered between the front and rear casing when removing
the upper cover. Re-solder if necessary. The ground connection prevents electrostatic charges
from building up on the surface of the terminal.
