7 Further operating information for hygenic areas
The emergency stops / switch-off devices SNH 0300 are among others suitable for the use
for machines in the food industry, splash zones as well as for non-food areas (definition acc.
to DIN EN 1672-2 and DIN ISO 14159)
For such applications the following has to be considered:
Operational conditions:
Operating temperature: -30 °C up to +50 °C (short-time up to +70 °C)
A continuous contact with hydrocarbon (e.g. petrol, oil, grease etc.) has to be avoided.
Limited UV resistance, a continuous outside application without additional protection is
not recommended.
Mounting
The emergency stops / switch-off devices are designed
for the installation in an enclosure or switching cabinet
onto a plain, preferably metallic, surface (e.g. front
panel).
Prior to the assembly the sealing lip of the yellow flexi-
ble collar (see figure) has to be greased with the sup-
plied grease, e.g. with the finger.
• Wear gloves made of nitrile rubber.
• The excessive grease has to be removed without damaging the sealing lip.
• Grease surrounding edge!
Material thickness for mounting the SNH 0300: 1 to 6.5 mm
Please consider the recommended tightening torque for the fixing nut in Section 8.1 "Tight-
ening torques for the fixing nuts", p. 23.
A mounting grid of at least 50 mm between the outer edges of the actuators has to be kept
in order to allow an easy cleaning between the actuators.
We recommend an appropriate mounting position, preferably for horizontal operation in
order to allow a flow off of liquids in the nonoperated as well as in the operated condition
(fold).
