1.2 Safety precautions during installation
1. Place the device where the ambient air is cool and as clean as possible. Consult section Reference
conditions and limitations.
2. During installation or any other intervention on one of the connected machines, the machines must be
stopped, de-energized and the isolating switch opened and locked before any maintenance or repair.
As a further safeguard, persons switching on remotely controlled machines shall take adequate
precautions to ensure that there is no one checking or working on the machine. To this end, a suitable
notice shall be affixed to the start equipment.
3. Install the equipment in an area free of flammable fumes, vapours and particles, e.g. paint solvents,
that can lead to internal fire or explosion.
4. The electrical connections must correspond to the applicable codes. The device must be earthed and
protected against short circuits by fuses in all phases. A lockable power isolating switch must be
installed near the device.
5. For machines controlled by a central control system, a sign stating "This machine may start without
warning" must be affixed near the instrument panel.
6. In multiple compressor systems, manual valves must be installed to isolate each compressor. Non-
return valves (check valves) must not be relied upon for isolating pressure systems.
7. Never remove or tamper with the safety devices.
Also consult following safety precautions: Safety precautions during operation and
Safety precautions during maintenance or repair.
These precautions apply to electrical devices.
For precautions applying to the connected equipment consult the relevant instruction
book.
Some precautions are general and cover several machine types and equipment; hence
some statements may not apply to your device.
