High power did not enable within the allowed amount of time and the servos reported no other error during the timeout period. For non-Adept robots use the SPEC utility to increase the value of the high power time-out. For Adept robots double-check your installation (cabling AC power line voltages circuit breakers amplifier retaining screws cables and contactors). For information about the correct configuration for installation refer to your Robot Instruction Handbook. Make sure that the amplifier chassis is properly connected to a power source and is turned on. Try again. If the problem persists contact Adept Customer Service.
