Cell lifter
The power cells of SINAMICS PERFECT HARMONY GH180
drives can be replaced as a unit. To replace, the entire power
cell must be removed from the drive and transported on a cell
lifter. Appropriate cell lifters are available for air-cooled
SINAMICS PERFECT HARMONY GH180 drives.
Accessories for grounding and short-circuiting the drive
For safety reasons, when working on the drive, which is in a no-
voltage condition, equipment must be provided to ground and
short-circuit the drive (IEC 61230). This equipment is required,
for example, when commissioning the system or when carrying
out service work such as replacing fans or power cells.
The specified equipment must be available on the plant or sys-
tem as this work is, to some extent, carried out by appropriately
qualified personnel belonging to the operating company. If the
specified safety equipment is not available, then it is not permis-
sible to carry out work on the plant or system due to the electrical
hazards which are present.
For SINAMICS PERFECT HARMONY GH180 drives, spherical
grounding points are provided at the voltage AC input/output,
which are short-circuited using an appropriate three-phase
grounding harness. This must always be connected before
starting any type of work when the system is in a no-voltage
condition.
If the feeder cables to the AC input/output are interrupted, then
it is also necessary to ground the interrupted cable a second
time, e.g., at the line supply connection of the drive involved. A
grounding harness with universal terminals can be used for this
purpose.
If the appropriate equipment is not available on the plant/sys-
tem, then the appropriate quantity of drive accessories must be
ordered.
The following grounding harness can be ordered.
