15-4 Commissioning, Operation and Maintenance MKE UL/CSA
DOK-MOTOR*-MKE*UL/CSA*-PR01-EN-P
Battery exchange
Rexroth Indramat drive control devices reliably monitor the battery voltage
and issue the warning “F248 Low battery voltage” in time.
DANGER
Danger of explosion! Death, severe injury and
damage to equipment by opening the motor
housing in explosion-endangered areas!
Þ Do not unscrew the housing screws if the motor is
located in an explosion-endangered area.
Þ In order to exchange the battery, the MKE motor must
be removed from the Ex area.
The battery should be exchanged when the control voltage is switched on.
This is required to prevent data loss in the motor feedback (switching off
the control voltage can lead to the loss of absolute values).
Prepare the following tools and spare parts:
· Allen key for
MKE037 size 2.5
MKE047 size 3
MKE098 size 4
· pointed pliers
· torque wrench with 1.3 – 6.8 Nm adjustment range
· new ready-made battery for
MKE037 and MKE047 part No. 277 133
MKE098 part No. 281 394
DANGER
Danger to life and limb due to electrical power!
In order to exchange the battery, work must be carried
out while the control voltage is switched on.
Therefore:
Þ work on the electrical system may only be carried out
by professional electricians.
Þ switch off the power supply on the drive control
devices and ensure that it cannot be accidentally
switched back on!
DANGER
Dangerous movements!
Danger to life and limb, extreme injury and
damage to material!
Þ Switch off the power supply on the drive control
devices and ensure that it cannot be accidentally
switched back on.
Þ Replace the battery only when the control voltage of
the drive control devices is switched on. If the control
voltage is switched off while the battery is removed,
the dimensional references are lost and can lead to
improper movements after the voltage is switched
back on.
