Such risks may occur in the following circumstances:

Failure   to   heed   the   operating   instructions   and   all   the

safety notes these contain 

Any form of unauthorized tampering or alteration inside

the device 

Use   of   the   device   in   environments   or   conditions   for

which it is not suited 

Use of the device with an unsuitable power supply and /

or in conjunction with unsuitable peripheral equipment 

Use of the device  for any purpose other than that for

which it is intended 

Damage caused by electrostatic discharge or lightning.

DANGER

Risk of fatal injury through exposure to dangerously high

voltage

Such risks may occur in the following circumstances:

Use of the device with an unsuitable power supply and /
or in conjunction with unsuitable peripheral equipment 

Damage caused by electrostatic discharge or lightning 

Do  not  run  sensor  lines  in  the  vicinity  of  high-voltage

power cables. 

Before you touch any sensor lines, ensure that all static

electricity has been discharged.

DANGER

Warning - explosive atmospheres or substances

In the vicinity of various fuels or chemicals there is a risk of ex-
plosion.
