DANGER
Do not enter the system enclosure unless trained, certified, and authorized to do so by
S&C Electric Company. Physical entry into the PureWave UPS System should never be
attempted while the system is enabled or when the modules are online. Voltages up to
800 Vdc and 600 Vac should be expected under normal operating conditions. Dc voltage
is present even without the utility power connected.
The enclosure is meant to provide access for field troubleshooting purposes only when
the unit is properly grounded. Never, under any circumstances, open the enclosure doors
while it is online or has not been fully discharged and grounded. Failure to do this can
result in equipment damage, personal injury, or even death.
Figures 1 through 4 show the different enclosure configurations for the 250-kW, 500-kW,
750-kW, and 1000-kW PureWave UPS System enclosures, respectively
