The +24 V auxiliary power supply and also the power supply for the +24 V-
BR holding brake supply must be galvanically isolated with SELV output volt-
age according to EN 60950.
Failure to observe these precautions can result in severe injury and
equipment damage.
Caution! Hot surface
During operation, the housing of the servo drive can become hot and may
reach temperatures above 80 °C (176 °F).
Especially the rear side of the module carrier will get hot, if the system is not
mounted on a mounting plate in the cabinet. This is due to the related dissi-
pated breaking energy in the ballast resistor. See technical data of module
carrier.
Check (measure) the housing and the module rack temperature and wait until
it has cooled down below 40 °C (104 °F) before touching it.
Failure to observe this precaution can result in severe injury
Caution! Electromagnetic Fields (EMF)
Mortal danger!
Due to the electromagnetic fields generated during operation of the servo
drive system, people with pacemakers or implants are particularly at risk if
they are in the immediate vicinity of the device.
Caution must therefore be take to ensure that such persons maintain
the necessary safety distance of at least 2 m.
