
the user has to take suitable measures in order to prevent longer or
continuous disturbances that cause the supply voltage to exceed by 10% or
more;

the product must be protected against overheating due to mechanical or
electrical overloading.
1.3 Mechanical safety

Install the device following strictly the information in the section “4 -
Mounting instructions”;

mechanical installation has to be carried out with stationary mechanical
parts;

do not disassemble the encoder;

do not tool the encoder or its shaft;

delicate electronic equipment: handle with care; do not subject the device
and the shaft to knocks or shocks;

respect the environmental characteristics declared by manufacturer.
1.4 Operational safety

The described products are category 3 certified and are designed for use in
potentially explosive zones 2 (according to EN60079-15) and 22 (according
to EN60079-31). They are suitable for a safe use and a normal level of
protection in areas in which explosive atmospheres caused by mixture of
gases and vapors (zone 2) or dust (zone 22) are unlikely to occur and if they
do occur do so for a short period of time. They comply with the
constructional safety requirements of the temperature class T5 (T100°C =
+212°F).
They are not to be used in Zones 0, 1, 20 and 21
;

protection requirements: Zone 2, gas explosion protection (G): protection by
non sparking equipment: the construction minimizes the occurrence of
sparks, arcs or hot surfaces, which in normal operation might give the risk of
explosion; Zone 22, dust explosion protection (D): the construction of the
product protects against the penetration of dust in hazardous quantities
(min. IP5x) and guarantees that the surface temperature is under the ignition
temperature of dust/air mixture as well as under the smoldering temperature
of dust deposits;

the manufacturer's specifications (temperature, speed, …) must under no
circumstances be exceeded;

max. permissible environmental temperature: -20°C +40°C (-4°F +104°F) at
continuous rotational speed of max. 6000 rpm;

the maximum surface temperature (in °C) of the product must not exceed
2/3 of the ignition temperature of the dust/air mixture;

in continuous operation the plastic parts must be able to withstand a
temperature 10°C higher than the maximum temperature that can be
reached in the hottest point of the product while the environmental
temperature is the highest allowed during operation.
