General notes
Our "General Terms and Conditions for Business" together with the "General Conditions for the Supply of Products and Services of the Electrical
and Electronics Industry" (ZVEI conditions) including supplementary clause "Extended Retention of Title" apply as the exclusive terms and conditions.
In additionIn addition, the following points are to be observed:
– These instructions must be read before installation and putting in operation and all notes provided therein are to be regarded!
– Devices must only be connected under dead-voltage condition. To avoid damages and errors the device (e.g. by voltage induction) shielded
cables are to be used, laying parallel with current-carrying lines is to be avoided, and EMC directives are to be observed.
– This device shall only be used for its intended purpose. Respective safety regulations issued by the VDE, the states, their control authorities,
the TÜV and the local energy supply company must be observed. The purchaser has to adhere to the building and safety regulations and has to
prevent perils of any kind.
– No warranties or liabilities will be assumed for defects and damages arising from improper use of this device.
– Consequential damages caused by a fault in this device are excluded from warranty or liability.
– These devices must be installed by authorised specialists only.
– The technical data and connecting conditions of the mounting and operating instructions delivered together with the device are exclusively
valid. Deviations from the catalogue representation are not explicitly mentioned and are possible in terms of technical progress and continuous
improvement of our products.
– In case of any modifications made by the user, all warranty claims are forfeited.
– Operating this device close to other devices that do not comply with EMC directives may influence functionality.
– Dimensions of enclosures or enclosure accessories may show slight tolerances on the specifications provided in these instructions.
– Modifications of these records are not permitted.
– In case of a complaint, only complete devices returned in original packing will be accepted.
These instructions must be read before installation and putting in operation and all notes provided therein are to be regarded!

Mounting and Installation
Permissible approach velocities (flow rates)
for crosswise approached protective tubes in water.
The approaching flow causes protective tube to vibrate.
If specified approach velocity is exceeded even by a marginal
amount, a negative impact on the protective tube's service
life may result (material fatigue).
Discharge of gases and pressure surges must be avoided
as they have a negative influence on the service life and may
damage the protective tubes irreparably.
Please observe maximum permissible approach velocities
for stainless steel protective tubes 9 x 1 mm (1.4571)
(see graph THR - VA - 09 ⁄ xx)
for stainless steel protective tubes 17 x 1 mm (1.4571)
(see graph THR - VA - 17 ⁄ xx)
for brass protective tubes 8 x 0.5 mm
(see graph THR - ms - 08 ⁄ xx)
