WARNING
The high flow velocities during the injection process can result in an
electrostatic charge.
Static discharges can result in fire and explosions.
Make sure that the machine is correctly grounded!
➤
Always use open, electrically conductive containers!
➤
Set the container down on a grounded surface.
➤
Never convey cleaning agents or materials containing cleaning agents
➤
into narrow-mouthed cans or barrels with a bung opening!
When using metal containers, make sure that the mixing unit is in
➤
continuous contact with the container wall.
Only use conductive material hoses.
➤
All original material hoses from WIWA are conductive and designed for
our machines.
WARNING
If the machine becomes contaminated with coating material during spraying,
a static charge may result due to the increasing coating thickness. Static
discharges can result in fire and explosions.
Clean the machine of contaminants through injection material
➤
immediately.
Perform the cleaning work outside of potentially explosive areas.
➤
WARNING
Machines that are not explosion-protected must not be used in operating
facilities that fall under the explosion protection ordinance!
Explosion-protected machines can be identified by the corresponding
mark on the type plate and/or the ATEX declaration of conformity provided.
Explosion-protected machines meet the requirements of the ATEX Directive
for the device group, device category and temperature class cited on the type
plate or in the declaration of conformity.
The owner is responsible for designating the zoning in accordance with ATEX
Directive, Appendix II, No. 2.1–2.3 in accordance with the stipulations of the
responsible regulatory body. The owner is required to check and ensure that all
technical data and labeling comply with the applicable stipulations according to
ATEX.
Please note that some parts have their own type plate with separate labeling
according to ATEX. In this case, the lowest explosion protection of all labels
displayed applies to the entire machine. For applications, whereby a failure
of the machine could lead to dangers to personnel, the owner is required to
implement appropriate safety measures.
