ATTENTION: To avoid an electric shock hazard, verify that the

voltage on the bus capacitors has discharged completely before

servicing. Check the DC bus voltage between the DC+ and DC-

terminals, between the +DC terminal and the chassis, and between

the -DC terminal and the chassis. The voltage must be zero for all

three measurements.

ATTENTION: HOT surfaces can cause severe burns. Do not

touch the heatsink surface during operation on the SCR Bus

Supply. After Disconnecting power, allow time for cooling.

ATTENTION: The SCR Bus Supply contains ESD (Electrostatic

Discharge) sensitive parts and assemblies. Static control

precautions are required when installing, testing, servicing or

repairing this assembly. Component damage may result if ESD

control procedures are not followed. If you are not familiar with

static control procedures, refer to Allen-Bradley publication

8000-4.5.2, “Guarding Against Electrostatic Damage” or any

other applicable ESD protection handbook.

ATTENTION: Only qualified personnel familiar with SCR Bus

Supplies, adjustable frequency AC drives, and associated

machinery should plan or implement the installation, start-up, and

subsequent maintenance of the system. Failure to comply may

result in personal injury and/or equipment damage.
