Protection against impermissible temperature rise
Every machine must be protected against an inadmissible temperature rise. Observe the
following notes:
● Protect every machine according to IEC / EN 60079–14 using a current-dependent,
delayed, circuit breaker with phase failure protection corresponding to IEC / EN 60947 or
a similar device in all phases.
● Set the protective device to the rated current (value is stamped on the rating plate).
● Select the protective device so that the motor is thermally protected even with a locked
rotor.
● For explosion-protected electrical machines with type protection "Increased safety", also
monitor the starting (starting monitoring with EC type examination certificate according to
Directive 94/9/EC or IECEx–Scheme with Certificate of Conformity). When the rotor is
locked, the protective device must trip within the tE time (safe locked rotor time). This
requirement is satisfied if the tripping time is not longer than the specified tE time.
● Protect the windings in a delta connection in such a way that the tripping unit or relay is
connected in series with the winding phases. When selecting and setting the tripping unit,
define the rated value of the phase current. The phase current is 0.58 times the rated motor
current. Any thermal motor protection via direct temperature monitoring to be used in
addition to the motor starter protector is stated on the rating plate if required.
4.8
System-inherent frequencies
NOTICE
Machine damage caused by system resonances
The system consisting of the foundation and machine set must be configured and matched
in such a way that no system resonances can arise and result in the permissible vibration
levels being exceeded. Excessive vibrations can damage the machine set. The vibration limit
values according to DIN ISO 10816-3 must not be exceeded.

Transport and storage
4.9.1
Transport markings
The packing differs depending on the transport type and size. If not otherwise contractually
agreed, the packaging corresponds to the packing guidelines for International Standards for
Phytosanitary Measures (ISPM).
