Electrical Hazard Classifications
The following table describes electrical hazard classifications as per SEMI S2-0200.
Brooks Automation has designed the robot to require minimum need to conduct test-
ing or maintenance on subsystems that may be energized. Calibrations and adjust-
ments are performed with the power on and live circuits covered. No equipment
should ever be repaired or replaced with the power on.
The following are the four types of electrical hazards:
Table 2-1: Electrical Hazard Classifications
Classification
Description
Type 1
Equipment if fully de-energized.
Type 2
Equipment is energized. Energized circuits are covered or insu-
lated.
Type 3
Equipment is energized. Energized circuits are exposed and inad-
vertent contact with uninsulated energized parts is possible.
Potential exposures are no greater than 30 volts RMS, 42.2 volts
peak; 60 volts DC or 240 volt-amps in dry locations.
Type 4
Equipment is energized. Energized circuits are exposed and
inadvertent contact with uninsulated energized parts is possible.
Potential exposures are greater than 30 volts RMS, 42.4 volts peak,
60 volts DC, or 240 volt-amps in dry locations.
