4 Recurring technical checks
In order to guarantee faultless and durable function, inspections must be performed regu-
larly. The inspection intervals are determined by the machine designer according to danger
assessment. Those responsible for safety should text the emergency stop button at least
once per year by activating the button and checking for proper function. The following
points must be tested in every case:
• Mechanical and electrical function according to Section 3
No recognisable manipulation or damage
•
• Secure fastening of the components
Leak tightness of the cable entries
•
• No loosened cable connections
5 Behaviour in the case of an error
Complete functional test after rectification of the error.
Carry out a complete functional test after the rectification of an error according to Section

6 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 sourrounding edge!
Material thickness for mounting the SNH 0300: 1 to 6.5 mm
