York Medium Voltage Variable Speed Drive MVVSD30002K-84

Ensure all switches and circuit breakers are opened

Disconnect devices not intended for dielectric test, such as input surge suppressors

Perform dielectric test at 2.25 times the nominal system voltage plus 2,000 V phase-to-ground and phase-to-phase

Is the light or buzzer calibrated to indicate failure with an output current between 1.5 mA and 2.0 mA for every 1,000 V applied?

Check for hazardous voltages during dielectric testing

Set all devices to their normal off position before energizing incoming power

Verify MVVSD ratings match system data

Remove all blocks or temporary braces used for shipment

Clean out all metal chips, scrap wire, and other debris

Is there an appreciable accumulation of dust or dirt?

Clean the enclosure using a brush, vacuum cleaner, or a clean lint-free brush

Check the integrity of all bus bar supports for secureness and damage

Inspect the unit to ensure all components have been delivered

Check for any damage occurred during transit

Note any damage on the carrier's freight bill

Enter a claim for any evident damage

Report major damage to the local Johnson Controls representative

Describe necessary repairs or replacements made

Ensure all safety signs are visible and not obscured

Manually exercise all switches, relays, and other operating mechanisms

Check operating mechanisms for proper function

Check fan overload relays for correct selection and adjustment

Power Circuit Fuses Verification

Follow all installation safety precautions

Is the correct power source available?

Does the installation site meet all environmental specifications for NEMA 1?

Is the chiller in the correct working condition and ready to be started?

Are power factor correction capacitors (PFCCs) located on the power source side of the drive?

Ensure drive positioning allows ample clearance for cabinet doors and accessibility to controls

Describe any issues found during the check
