Installation Safety Precautions, continued
CAUTION!
CONTAMINATION AND THERMAL HAZARD
Ensure the 17S drive is mounted within an appropriately vented and closed
switchgear cabinet that is free of conductive and corrosive contaminants. Ensure
the ventilation clearances above and below the drive conform to requirements.
(Refer to Chapter 3 for additional information.)
Failure to observe this precaution can result in injury or equipment damage.
DANGER!
ELECTRIC SHOCK HAZARD
Residual voltages on the DC link capacitors can remain at dangerous levels for up
to five minutes after switching off the mains supply voltage. Therefore, measure the
voltage on the DC Link (+DC/-DC) and wait until the voltage has fallen below 40 V.
Control and power connections can still be energized, even when the motor is not
rotating.
Failure to observe these instructions will result in death or serious injury.
