PowerFlex DC Stand-Alone Regulator (SAR)

Field SCR Module and Dual Diode Module

What This Kit Includes

Rockwell Automation recommends that the field SCR module and dual diode

module be replaced at the same time.

• One field SCR module or one dual diode module

• Two mounting screws with captive lock washers

• Static strap

Tools That You Need

• Phillips

screwdriver

• Hexalobular screwdriver

• Isopropyl alcohol

• Thermal grease

ATTENTION: Only qualified personnel familiar with DC 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.

ATTENTION: To avoid an electric shock hazard, ensure that all power to

the SAR has been removed before performing the following.

ATTENTION: This SAR 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, reference A-B publication

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

applicable ESD protection handbook.
