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
mm
2
(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.
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.
