+DC Brake Power Wiring
-DC Brake Power Wiring
All DC Brake Power Wiring must be twisted pair
and run in conduit separate from Control Wiring.
Minimum required DC Brake Power Wiring sizes
are listed in tables 1b, 2b and 3b.
Control Wiring
All Control Wiring must be twisted pair and run
in conduit separate from DC Brake Power Wiring.
Interconnection Control Wiring between the
brake terminals must be twisted pair,
1 mm2 (18 AWG) minimum.
Optional Brake Fault Contact Wiring
A separate 115V AC power supply is required if
the brake fault contacts are to be monitored.
Refer to your 1336, 1336VT, 1336 PLUS, or
1336 FORCE User Manual for wire selection
and installation details.
Connect to AUX at TB3 — Terminal 24 for L6 Option
— Terminal 28 for L3 Option.
When more than KB050 or KC050 brake
is required, a separate user supplied Auxiliary Term
Block is also required — A-B Catalog Number 1492-PDM3141 or equivalent.
A separate 115V AC power supply is required to operate fans and enable the brake.
The MASTER OUT terminals are factory jumpered and must remain jumpered for single brake
applications. For multiple brake applications, remove the jumpers in all but the last enclosure.
Contact is shown in a de-energized state. Contact is closed when 115V AC power is applied to TB3 and
pilot relay is energized. Loss of power or a brake malfunction will open contact.
Connect the brake frame to earth ground. Refer to the connected drive's User Manual for grounding instructions.
