2 Safety

2.1 Safety instructions

This chapter contains instructions to prevent personal injury and property damage.

These instructions do not lay claim to completeness. In case of questions and problems,

please consult our company technicians.

Attention!

•Non-compliance with the information and safety instructions listed in these assembly

instructions can cause serious health and safety risks!

•It is essential to observe the notes in the motor manufacturer’s assembly instructions,

which are part of the scope of supply.

It is essential to observe the following points:

•The fans are exclusively intended for use in explosive atmospheres of Zone 1 and 2

for gases or Zone 21 and 22 for dust (see rating plate).

•The conveyance of solid matter or solids content in the conveying medium is not

permissible and can lead to dangerous situations. ZIEHL-ABEGG rejects any liability

for damage of any kind as a result of such use.

•Frequency inverters are only permissible if explicitly speciﬁed, up to a maximum

frequency of 50 Hz (for 50 Hz driven motors) or 60 Hz (for 60 Hz driven motors).

•The temperature classes of fan and motor are allowed to be different, but they must

be deﬁned according to the ignition temperature of conveying media.

•The fans must be operated in the temperature ranges speciﬁed on the rating plate.

•The operating data on the rating plate are speciﬁed for an air density of 1.2 kg/m

For example:

–Protection of the motor against unusual heating according to EN 60204

–Motor protection switches must be installed and set to the rated current speciﬁed

on the rating plate (a higher value is not permissible).

–The motor overheating protection equipment must be connected.

–Circuit breakers or overheating protection equipment not properly connected will

invalidate the manufacturer's warranty. Furthermore, this might lead to explosion

hazards.

–...

If the impeller is accessible, protective grilles must be installed according to EN 13857.

These must not be changed and must be adequately fastened.

Pay attention to objects at a greater height which might fall down.

Pay special attention to material combinations according to EN 14986.

Since a residual risk due to falling objects, incorrect behaviour, etc. cannot be completely

ruled out, the designer, operator or manufacturer of the installation or system in which

the fan is to be installed, must prevent any potentially hazardous situation from arising

by means of appropriate safety measures in line with standard EN ISO 12100 and

especially standard EN 14986.

The operator is responsible for maintenance of the fan.

Compliance with the EMC Directive only exists if the fan is directly connected to the

main power supply. If the fan is installed in a system or combined with other products,

the system manufacturer is responsible for compliance with the EMC Directive.

•The fans must be arranged at a reasonable distance from transmitters or be protected

by suitable shielding.

•The components (tubular housing, grille, etc.) made of stainless steel 1.4031 can

become magnetic through impact. This must be prevented by using austenitic and

non-magnetic steels (EN 14986).
