Emission

Danger!
Depending on the operating status, high surface temperatures are reached!
ƒ Risk of burns when touching.
– Surface temperature of the motors up to 95°C
ƒ If required, provide for protection against contact.
ƒ A limit value of 70dB (A) is not exceeded during rated operation. In the case of AC
motors, operating states during which higher noise emissions occur can appear.
ƒ The carbon brush debris inside GN and PM motors is composed of different metals,
graphite, possibly epoxy resin, or other binders.
Electrical connection
Important notes

Danger!
ƒ Have the electrical connection carried out by qualified personnel for
electronics only!
ƒ Carry out all connection operations in the deenergised state only! Danger
of unintentional start-ups or electric shocks.

Stop!
It has to be ensured that the supply voltage and the nameplate data comply
with each other.
The PM motors are to be operated with DC voltage. The voltage supply has to provide the
opportunity to start up the motors in a current-limited manner!

Stop!
ƒ Never exceed the maximum permissible peak current ”I
max
”! (15)
ƒ The motors as of size 55 may not be switched on directly when the rated
voltage is applied, as the starting current would exceed the permissible
peak current ”I
max
”.
