PSU2 spare power-supply module for SIMOVERT MASTERDRIVES units in design sizes J through M

Siemens identifies this exact order number as the PSU2 power-supply module for MASTERDRIVES devices with design sizes J through M. It is a discontinued spare, so the installed drive design and board identity must be established before procurement.

PSU2 replacement gate: Match the complete 6SE7038-6GL84-1JA1 number, the PSU2 designation, the host drive order number and design size, the existing board revision and every connector position before any exchange.

Drive Compatibility

Treat PSU2 compatibility as a host-drive and revision question, not as a visual board match.

Exact identity

Read the full host-drive and board order numbers; do not confuse the final -1JA1 suffix with another PSU variant.

Design size

Confirm that the installed MASTERDRIVES unit is within the Siemens J-through-M design range.

Revision evidence

Record the original board revision, connector keying and service history before selecting a spare.

Description

6SE7038-6GL84-1JA1 is not a universal control-power board. It belongs to the SIMOVERT MASTERDRIVES spare-parts system and Siemens limits the product description to PSU2 use in devices with designs J through M.

A controlled replacement begins with the complete drive nameplate, the fitted board label, connector photographs and the original fault record. Power must remain isolated until the DC link has been made safe under the machine service procedure.

Install & Service

Preserve the machine evidence and use the approved drive isolation procedure before moving the module.

Safe isolation

Isolate all power sources and verify the DC link is discharged according to the machine service documentation.

Connector map

Photograph and label every plug, ribbon cable and grounding point before removing the existing PSU2.

Controlled start

After installation, energize under a monitored service procedure and stop if abnormal control voltage, odor, heat or drive faults appear.

FAQ

How can I confirm that 6SE7038-6GL84-1JA1 fits my SIMOVERT MASTERDRIVES unit before purchase?

Provide the complete host-drive order number, design size, existing PSU label and clear board photographs. The Siemens description limits this PSU2 spare to designs J through M, and a similar connector layout alone is not sufficient evidence.

What should be documented before removing 6SE7038-6GL84-1JA1 from a failed drive?

Record the drive nameplate, PSU2 label and revision, connector locations, ribbon-cable orientation, grounding points and the first fault symptoms. Preserve the parameter and diagnostic records from the control unit whenever they can be obtained safely.

Why should 6SE7038-6GL84-1JA1 not be installed only by comparing the board shape?

MASTERDRIVES internal boards can look similar while serving different power-supply roles or revisions. Verify the full order number ending in -1JA1, the PSU2 designation and host-drive compatibility before applying power.

What safety checks are required before installing 6SE7038-6GL84-1JA1?

Follow the machine lockout procedure, isolate external and auxiliary supplies, wait the specified discharge time and prove the DC link is safe with suitable equipment. Do not unplug the module while the drive is energized.

How should I investigate a drive that still will not initialize after fitting 6SE7038-6GL84-1JA1?

Do not keep cycling power. Recheck every connector and ground, compare the replacement revision with the original, verify the upstream auxiliary supply and record the control-unit fault display. Continue with the Siemens drive service procedure before replacing more boards.

What information is needed to source a replacement for 6SE7038-6GL84-1JA1 in a discontinued system?

Send the exact PSU2 order number, host-drive order number, design size, board revision, serial information and photographs of labels and connectors. Also state whether the request is for an operational spare, repair exchange or a planned migration to SINAMICS.
