STORAGE
In this chapter we describe, how you decommission and store the device.
10.1 Safety instructions
h
Refer to
from page 11 and the information in
The shutdown of the device may only be carried out by for this qualified personnel.
DANGER!
Risk of fatal injury from electrical current!
Stored electric charge.
Discharge time of the system = discharge time of the device with the longest DC link
discharge time.
Therefore:
m
Do not touch electrically live parts before taking into account the discharge time of
the capacitors.
m
Assure, that all electric connections are current-free and are safe against switch-
on.
m
Before working, check at the electrical connections with suitable measuring devic-
es, that the connections are off-circuit.
m
Remove the connections not until the safe isolation from supply has been checked.
m
If additional capacitors are connected to the DC link, the DC link discharge can
take a much longer time. In this case, the necessary waiting period must itself be
determined or a measurement made as to whether the equipment is de-energized.
This discharge time must be posted, together with an IEC 60417-5036 (2002-10)
warning symbol, on a clearly visible location of the control cabinet.
