DANGER
Danger from unintentional activation of the product
Severe injury including death possible
•
Any work on the electrical grid and on live components may only be performed by
an electrician.
•
Follow the safety rules for working on electrical products.
•
When working on the product, switch off all products connected to the potential-free
contact at their main switch and secure them with a padlock against reactivation.
•
Isolate all products connected to the potential-free contact; e.g. pull all mains con-
nectors.
An option for connection is start-up via an external potential-free contact between the
product and the processing machine. The product is started or stopped by the processing
machine. The external potential-free contact is connected to a plug connector at 1 and 2.
The potential equalisation is connected to “protective earth”. Additional details are listed in
the accompanying circuit diagrams.
The toggle switch must be set to “AUTO” for this operating mode.
As soon as the main switch is set to “ON”, the contacts of the product’s black socket carry
live voltage.
During maintenance work on the connected processing machines and products or control
units, the control line to the dust extractor must be disconnected. Set all main switches to
the “0” position and secure with a padlock against unintentional start-up. Disconnect all
mains connectors.
Always disconnect the power cable from the control box when performing maintenance
work on the
dust extractor
. The main switch must be located in the "0" position and se-
cured against unintended commissioning with a padlock. The dust extractor is to be dis-
connected from the mains.
When performing maintenance work on the connected
processing machine
and devices
or control units, disconnect the power cable from the dust extractor; all main switches
must be in the "0" position and are to be secured against unintended commissioning with
a padlock if possible. Disconnect all mains connectors. If this is not possible, take all suit-
able measures to ensure that all machines are isolated voltage-free. This applies to all
machines connected to the plant.
