WARNING!
Wait for the capacitors to discharge. The discharge time is five minutes.
CAUTION!
When drilling, ensure that terminals and contacts in the connection area do
not become dirty or wet.
The mounting bracket without a power stage set does not conform to the
protection class of the inverter as a whole, and therefore must not be in-
stalled without a power stage set.
The mounting bracket should be protected from dirt and moisture during in-
stallation.
the inverter is placed in the mounting bracket and permanently attached us-
ing screws，
the cover for the data communication area is permanently attached to the
inverter with screws.
WARNING!
The housing screws provide a suitable ground conductor connection for
grounding the housing and must NOT be replaced by any other screws that
do not provide a reliable ground conductor connection.
