mark
Meaning
The UL Recognized Component Mark (UL recog-
nized) identifies recognized component parts
which are components of a bigger product or
system. The recognition refers to the UL standards
1004-1 „Rotating electrical machines –General
requirements“, UL 1004-6 „Servo and stepper
motors“, CSA C22.2 No. 100 „Motors and genera-
tors“.
0158
The CE-marking confirms the conformity of a
product with relevant EC-regulations.
The conformity of MKE motors is confirmed
according to low voltage directive 2014/35/EU,
ATEX directive 2014/34/EU, EN
60034–1 and
EN
60034–5. In addition, the (4-digit) identifica-
tion number of the notified body is indicated
25
2021
Motors labelled with the symbol EFUP 25 (enviro-
mental-friendly use period) can be use for 25 as
intended before substances limited in their concen-
tration according to China RoHS2 may leak and
subsequently pose a risk to environment and
health.
The year of manufacturing is notified under the
symbol.
