Installation location and clearances for the brake resistor
A Micromaster 4 brake resistor is required when you use a non-self-locking gear for the drive
unit of the EMS carrier. Plant engineering specifies the type of brake resistor that suits the
plant conditions.
The brake resistor dissipates heat in form of radiation and convection. Install the brake
resistor so that a thermal effect on the carrier controller is prevented. Observe the necessary
clearances around the carrier controller.
For information about the mounting and wiring of the Micromaster 4 brake resistor, refer to
the corresponding product documentation. This documentation is available at:

Wiring information
Note
Observe the following points:
•
Safety instructions
Read the "Safety instructions" section in the "EMS400S Carrier Controller for Electric
Monorail Systems" system manual.
•
Device failure
Moisture and condensation lead to malfunction. Moisture in form of condensation at or in
the device is the result of extreme fluctuations in temperature that occur, for example,
when the device is transported at low temperatures. Bring the device to room
temperature before operating.
•
Condensation
Wait for approximately 4 hours to completely dry out any condensation before you
connect or power up the device. Do not expose the device to direct heat radiation from a
heater.
