Conditions on site

1)
With fitted plugs of the same protection class.
PAD4001A/4003A
The PAD is hermetically encapsulated by laser welding
and is made from materials that do not rust. They are
therefore largely impervious to humidity and moisture.
The devices achieve protection classes IP68 (test condi­
tions: 100 hours under 1 m water column) and IP69K
(water at high pressure, steam cleaning), as per DIN
1)
EN 60529 . The devices should nevertheless be protec­
ted against the long-term effects of moisture and humid­
ity.
Important
Note that when using a steam cleaner, the conditions
stated in EN 60529 under degree of protection IP69K
such as max. pressure, max. temperature, etc., must be
met.
Protection against corrosion
The device must be protected against chemicals that
could attack the steel of the housing, the plugs or the
cables.
Information
Acids and all substances that release ions also attack
stainless steels and their seam welds.
Subsequent corrosion can cause the device to fail. If this
is the case, you must provide appropriate means of pro­
tection.
