9.2 Fan Maintenance

9.2.1 Fan Assembly Troubleshooting

Any safety hazards stemming from the device must be re-evaluated once it is installed in the end device.

Do not make any modifications, additions or conversions to the fan assembly without the approval of Vertiv.

WARNING! Risk of electric shock. Can cause serious injury or death. Open all local and remote electric power
supply disconnect switches and verify with a voltmeter that power is off before opening the fan motor
electric connection enclosure. Use only fully trained and qualified HVAC technicians to replace or perform
maintenance on the EC fans.

WARNING! Risk of contact with high speed rotating fan blades. Can cause serious injury or death. Open all
local and remote electric power supply disconnect switches, verify with a voltmeter that power is off, and
verify that all fan blades have stopped rotating before working in the unit cabinet or on the fan assembly. If
control voltage is applied, the fan motor can restart without warning after a power failure. Do not operate the
unit with any or all cabinet panels removed.

CAUTION: Risk of exposure to harmful noise levels. Can cause hearing injury or loss. Depending on the
installation and operating conditions, a sound pressure level greater than 70 dB(A) may arise. Take
appropriate technical safety measures. Operating personnel must wear appropriate, OSHA-approved PPE
and observe all appropriate hearing protection safety requirements.

CAUTION: Risk of contact with hot surfaces. Can cause injury. The fan motor, and some electrical
components are extremely hot during unit operation. Allow sufficient time for them to cool to a touch safe
temperature before working within the unit cabinet. Use extreme caution and wear appropriate, OSHA-
approved PPE when working on or near hot components.

NOTICE

Risk of improper power supply connection. Can cause equipment damage and loss of warranty coverage.

Prior to connecting any equipment to a main or alternate power source (for example: backup generator
systems) for startup, commissioning, testing, or normal operation, ensure that these sources are correctly
adjusted to the nameplate voltage and frequency of all equipment to be connected. In general, power source
voltages should be stabilized and regulated to within ±10% of the load nameplate nominal voltage. Also, ensure
that no three phase sources are single phased at any time.

NOTE: Do not assume that the fan blades will not start to spin. If the motor is in a fault condition, it will safely shut
down. Once the fault condition is cleared, there are certain conditions in which the motor will automatically resume
operation.
