Mail-in instructions

Five minutes of good packing protects a four-figure unit. Here's exactly how to send it — and where.

Before you remove the unit

  • Get an RMA first — start a repair or quote online so your unit is expected and trackable.
  • Power down and lock out the machine per your facility's LOTO procedure.
  • Photograph the wiring and connector positions before unplugging anything — future-you will thank you at reinstall.
  • For CNC boards: back up machine parameters and programs first. That's best practice for any board removal, repair or not.
  • Note the exact part number and serial from the unit's label on your order if you haven't already.

What to send (and what to keep)

  • Send the failed unit only — no cables, mounting brackets, doors, or bezels unless we ask.
  • Keypads/covers that are part of the fault (worn membrane) should stay on the unit.
  • CF/SD cards: keep them if you prefer — we test with our own media. If the application only lives on the card, note it on the intake so we image it first.
  • Indramat/Ecodrive: leave the firmware module installed — it stays with your unit through the whole process.
  • Include a note inside the box with your RMA, name, and a one-line failure description.

Packing that survives the truck

  • Bare boards: anti-static bag first, always. No foam peanuts directly against electronics.
  • Two inches of firm padding on every side — foam, bubble wrap, or crumpled kraft. The unit should not move when you shake the box.
  • Double-box heavy units (drives over ~15 lb): padded box inside a padded box.
  • Screens face-down on a foam sheet, never against a bare box wall.
  • Tape all seams. Write the RMA large on two sides of the box.

Shipping

  • Any carrier works — USPS to the PO Box, UPS/FedEx to the street-address form of the same box (both below).
  • Insure the shipment for the unit's replacement value; carriers only honor claims on insured, well-packed boxes.
  • Machine down? Overnight it and choose rush/emergency service so it hits the bench first.
  • Units over 50 lb (large VFDs, spindle drives, industrial PCs in enclosures) ship by freight — contact us before ordering and we will arrange dock-to-dock shipping.
  • Reply to your confirmation email with the tracking number and we'll watch for arrival.
