In potentially explosive areas, MKE037, -047, -098 and -118 motors
must only be operated with Rexroth drive control devices.
When mounting the drive control devices in potentially explosive areas, the
following components must fulfill the Ex protection requirements.
●
Motor with attached parts
●
Circuits leading into the potentially explosive area

Potentially explosive area
Use in zone 1 and 2
It is allowed to use MKE motors of Rexroth Indramat in hazardous areas of zone
1 and 2.
The related drive control devices and connections of the connection cables
(power and encoder connection) must lie outside of the potentially explosive
area.
DANGER
Danger of explosion, danger to life, heavy injury and material damage
⇒ Do not set up drive control devices or connectors in potentially explosive
areas.
⇒ Make sure that connectors cannot reach into the hazardous areas.
⇒ Do not disconnect the connections under load!
⇒ Make sure that no ignition sparks could occur within the hazardous area.
