1.2 Safety precautions during installation

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
