2 Workspace Preparation
2.1 Power Source
The standard BarrettArm system requires a 3-phase, 60 Hz, 220 VAC electrical supply capable
of at least 20 amperes output. For other international voltages and/or for 50 Hz operation, an
isolation transformer may be added to convert several voltages to 220 VAC.
The circuit breaker on the control cabinet protects internal power components from power
surges. This breaker should not be bypassed for any reason.
2.2 Mounting Requirements
The lab mounting-surface for the BarrettArm should be designed to handle the large reaction
forces generated at the base of the arm during high-acceleration operation. The BarrettArm can
be fastened to the prepared mounting-surface through the integrated bolt flanges in the base
plate. Four M8-1.25 (or 3/8”-16) taps should be machined into the lab mounting-surface
according to Figure 6 in order to mate with the arm pattern.
