Connection Techniques

Check the fit and precision of the connection before carrying
out the electrical connection.
Danger of explosion due to improper handling
when connecting the motor!
⇒ Ensure that the power is off and that the motor is
connected only in an atmosphere that is not capable
DANGER
of explosions.
⇒ Before working on the system, always use a suitable
measuring instrument (e.g. multimeter) to assure
that the parts no longer have a residual voltage (e.g.
due to the residual energies of capacitors in filters,
drive devices, etc.). Wait for their discharging time.
⇒ The connection between the ground-reference lug
and the grounding conductor must be made before
any other connections.
⇒ In particular, heed a sorted and de-energized laying
of the connection cables within the terminal box to
avoid abrasion or pressure marks on the cables.
⇒ The connection points to or on the control device
must be located outside of the hazardous area.
⇒ The motors may be operated only with Rexroth
IndraDrive drive control devices. Control devices
from other manufacturers are not permitted.
The motors have to be grounded over the motor cable and a separate
grounding wire with min. 4 mm² cross-section (see. Fig. 5-7). The power
connection is located on the top and is provided only as a terminal box in
the case of explosion-protected motors.
The following connections must be made to ensure safe operation of the
motors:
• power connection (incl. temperature sensor and holding brake)
• encoder connection
• equipotential bonding conductor connection (according to EN
50014:2000, Chapter 15)
• Coolant Connection
• Connection of the scavenging device with safety control.
