Electrical Shock Hazard
If a fuse is open or earth leakage circuit breaker (ELCB) is tripped, check the wiring and the selection of the
peripheral devices.
Contact your supplier if the cause cannot be identified. Failure to comply may result in electrical shock by indirect or
direct contact. The regenerative unit can cause a residual current with a DC component in the protective earthing
conductor.
After blowing a fuse or earth leakage circuit breaker (ELCB) is tripped, do not attempt to restart the unit or
operate peripheral devices until five minutes pass and CHARGE lamp is OFF.
Failure to comply could result in death, serious injury, and damage to the unit.
Do not connect or disconnect wiring while the power is on.
Failure to comply could result in death or serious injury.
Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power
supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent
electric shock, wait for at least the time specified on the warning label; after all indicators are OFF, measure for unsafe
voltages to confirm the unit is safe prior to servicing.
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
