DANGER
Electric shock!
Danger of death due to electrical voltage when assembling/
disassembling the device.
► Switch off transformer on high-voltage side and low-voltage side.
► Lock transformer to prevent unintentional restart.
► Make sure that everything is de-energized.
► Visibly connect all transformer terminals to ground (grounding leads,
grounding disconnectors) and short circuit them.
► Cover or cordon off adjacent energized parts.
This chapter describes the installation of the shutter valve as well as the
electrical connection of the reed switches.
5.1 Checking the pipe flanges
The pipe flanges must be flush and clean to allow the device to be posi-
tioned with the least possible stress.
NOTICE! A residual distance between the flanges caused by a deviation in
evenness can cause damage to the flanges.Even slight unevenness can
cause the flange of the device to be curved too much, leading to cracks in
the flange caused by the resulting transverse stress.
Therefore, check the following:
▪ Pipe flanges
– Flush and even
– Evenness deviation ≤0.2mm
