Mounting Requirements Dynamic brake enclosures must only be installed in the vertical position.
Select a location using the guidelines below and information provided in
the Recommended Brake Configurations section.
• Each dynamic brake enclosure must be mounted outside of any other
enclosure or cabinet and exposed to unrestricted circulating air for
proper heat dissipation. Allow a minimum of 304.8 mm (12 in.)
between brake enclosures and all other enclosure or cabinets including
the drive.
• Each enclosure must be mounted in an area where the environment
does not exceed the values listed in the specification section of this
publication.
• If only one dynamic brake enclosure is required, the enclosure must be
mounted within 3.0 m (10 ft.) of the drive.
• If more than one KB050 or KC050 brake enclosure is required, a
separate user supplied terminal block must be mounted within 3.0 m
(10 ft.) of the drive. Allow a maximum distance of 1.5 m (5 ft.)
between each brake enclosure and the terminal block.
• If more than one KA005-KA010, KB005-KB010 or KC005-KC010
brake enclosure is required, the first enclosure must be mounted within
3.0 m (10 ft.) of the drive. Allow a maximum distance of 1.5 m (5 ft.)
between each remaining brake enclosure.
• Separate conduit must be provided for the control connections
between multiple brake enclosures.
• Separate conduit must be provided for the DC power connections
between brake enclosures, the terminal block (if required) and the
drive. For AC power connection and conduit requirements, refer to
your 1336, 1336VT, 1336 PLUS II, or 1336 FORCE User Manual.
IMPORTANT: The National Electrical Codes (NEC) and local regulations
govern the installation and wiring of the Heavy Duty Dynamic Brake. DC
