Distillation Process Analyzer DPA-4.5

Safety

2.5.2 Warnings

Danger of explosion

Sticker 1 (see p. 34)

WARNING
Danger of explosion due to ignition sources
inside

Hot surfaces inside the measuring unit box can
ignite an explosive atmosphere.

For this reason:

– Turn off the power supply before opening and

wait for 25 minutes.

Sticker 2 (see p. 34)

WARNING
Danger of explosions due to electrostatic
discharge

Cleaning plastic surfaces with a dry cloth can result
in static discharge. Any sparks could ignite a
potentially explosive atmosphere.

For this reason:

– Always clean plastic surfaces with a damp cloth.

Sticker 4 (see p. 34)

WARNING
Danger of explosion due to ignition sources
inside

Hot surfaces and residual charges of electronic
components inside the control box can ignite a
potentially explosive atmosphere.

For this reason:

– Switch off the voltage supply and secure it from

being switched on again and wait 5 minutes to
ensure that hot surfaces have cooled and
residual charges have discharged before
opening.
