______________________________________________________________________________________________
!
SPECIAL CONDITIONS FOR SAFE “X” USAGE :
Risk from electrostatic charges
Prevent electrostatic charging of external insulating surfaces by using the appropriate installation and cleaning
measures. To clean external insulating surfaces use a damp cloth.
Connect the conditioning units to the earth.
When combined with other conditioning units, ensure that all metallic and conductive parts are always intercon-
nected and linked to the earth to avoid significant electrostatic charges being created.
The earth is connected to the unit or to the combination of conditioning units by the downstream and upstream
use of metal pipes connected to the earth. If the pipes are non-conductive, earth connection should be performed
by the assembly and/or fixing devices adapted to the ATEX products.
______________________________________________________________________________________________
Installation, commissioning and servicing and maintenance
These operations may only be carried out by authorised personnel and in accordance with the usage instructions.
Only carry out maintenance in zones where there is no explosive atmosphere.
If during maintenance it is established that wearing and spare parts need exchanging, contact an ASCO
Numatics reseller.
Any modification of the product with parts not supplied by the manufacturer will invalidate the certification.
