NOTE
Bypass volts are calibrated only at the System Control Cabinet (SCC). Input amps, DC volts,
DC amps and temperature are calibrated only at the UPS modules.
!
CAUTION
Meter calibrations are factory-set and should not require adjustment. Contact Liebert Global
Services for meter calibration.
!
WARNING
Do not attempt to calibrate meters without adequate training. Meter calibration requires
special test equipment, access to test points in sensitive circuitry and exposure to hazardous
voltage.
