Mains Operation - WIKA CPH62I0 Betriebsanleitung

3. Safety
Pressure sensor
Only use model CPT62I0 pressure sensors! The use of other pressure sensors can
■
result in the destruction of the measuring instrument and of the pressure sensor.
When using two model CPT62I0 pressure sensors, make sure that these don't rest on
■
EN
surfaces nor are screwed into items which are at a different potential!
For the electrical connection between the model CPT62I0 pressure sensor and the
■
CPH62I0-S1 or CPH62I0-S2 hand-held pressure indicator, use only the original WIKA
sensor connection cable intended for this. This also applies to the extension cable,
thus reaching a maximum permissible overall cable length of just under 5 m (16.4 ft).
Analogue output
The use of the analogue output is not permitted in hazardous areas!
■
Only connect passive voltmeters to the analogue output.
■
Equipotential bonding
All components (pressure sensor, power supply unit, interface, etc.) connected to the
■
instrument must be at the same potential or connected via equipotential bonding.
For use in potentially explosive atmospheres, only connect pressure sensors!
■
With two connected pressure sensors, take care that these are connected to the same
electrical potential, or an equipotential bonding exists.
Non-intrinsically safe use
The hand-held pressure indicator can also be used as a non-intrinsically safe instrument
for connection to non-intrinsically safe instruments (e.g. interface cables).
In this operating state also, only use approved accessories!
■
Before reusing the hand-held pressure indicator as an intrinsically safe instrument,
■
prior to insertion into the leather case, make a general check for external damage and
functionality of the instrument and the leather case!
Transport and storage cases
The optionally available transport and storage cases are not approved for use within
hazardous areas! The cases must always be stored outside the hazardous area.

3.6.2 Mains operation

DANGER!
Danger to life due to loss of explosion protection
Non-observance of these instructions and their contents may result in the
loss of explosion protection.
