7 Electrical Installation and Wiring
Pay attention when choosing the cable. It must meet and be installed according to all locally
applicable codes, and must be suitable for the environment it is going to be installed in.
Always use a shielded cable when possible. Make sure to connect the shield to a protective
earth potential at a single location.
Use a minimum of 0,3 mm
When connecting the cabling make sure to leave enough slack to allow for the device to be
removed from the process for cleaning without disconnecting the cables form the dust
monitor.
Always turn off and unplug the Dumo when you are not using it, when you intend to clean it, or in
the event of a malfunction.
Only connect the Dumo if the line voltage of the socket corresponds to the data on the rating plate.
Stand on an insulating pad and make it a habit to only use one hand when checking components.
Always work with another person in case an emergency should occur.
Disconnect power before checking the Dumo or performing maintenance.
Make sure all equipment is properly grounded.
Always wear safety glasses when working on the power supply.
Read and understand User Manual before installation.
