Fire Hazard
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire.
Verify that the rated voltage of the regenerative unit matches the voltage of the incoming power supply before applying
power.
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
Do not use improper combustible materials.
Failure to comply could result in death or serious injury by fire.
Do not install the regenerative unit to a combustible surface. Never place combustible materials on the regenerative
unit.
Crush Hazard
Only allow qualified personnel to operate a crane or hoist to transport the regenerative unit.
Failure to comply may result in serious injury or death from falling equipment.
CAUTION
Do not carry the regenerative unit by the front cover or the terminal cover.
Failure to comply may result in minor or moderate injury from the main body of the regenerative unit falling.
NOTICE
Do not disconnect the wiring to the regenerative unit while the regenerative unit is outputting a voltage.
Improper equipment sequencing could result in damage to the regenerative unit.
Connect a power supply with a capacity (kVA) that is larger than the rated input capacity (kW) of the
regenerative unit.
Failure to comply could result in damage to the regenerative unit.
Observe proper electrostatic discharge procedures (ESD) when handling the regenerative unit, circuit boards,
and CMOSIC.
Failure to comply may result in ESD damage to the regenerative unit circuitry.
Do not perform a withstand voltage test on any part of the regenerative unit.
Failure to comply could result in damage to the sensitive devices within the regenerative unit.
Do not operate damaged equipment.
Failure to comply could result in further damage to the equipment.
Do not connect or operate any equipment with visible damage or missing parts.
Install adequate branch circuit short circuit protection per applicable codes.
Failure to comply could result in damage to the regenerative unit.
The regenerative unit is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes,
240 Vac maximum (200 V Class) and 480 Vac maximum (400 V Class).
Prevent foreign matter such as metal shavings or wire clippings from falling into the regenerative unit during
regenerative unit installation and project construction.
Failure to comply could result in damage to the regenerative unit. Place a temporary cover over the top during
installation. Be sure to remove the temporary cover before start-up, as the cover will reduce ventilation and cause the
regenerative unit to overheat.
