FAQs - Mainframes
How do I modify my mainframe to work on single-phase 240V?The back panel has a full schematic of where each wire should be attached in the mainframe. The brass terminals have “fast-on” connectors attached to the end of each wire that you need to move according to the schematic on the back panel. You can also consult your user manual or section-Q in the D-M-E catalog.
What is the anti-arc clip used for in the mainframe?
The clip is used to inhibit the triac from outputting any power until the module is fully inserted into the mainframe. This will assist in preventing arcing of the gold fingers when the controllers are accidentally inserted or removed while the power is turned on. The clip is installed in the 3rd position of each of the white edge connectors in the mainframe. Newer anti-arc equipped modules will not output any power until this anti-arc clip is installed in the mainframe. All mainframes built after January 1999 have this clip already installed in them.
What is the part number for the anti-arc clip used in the mainframe?
D-M-E replacement part number RPM0046 (sold in packs of 20).

What is the replacement part number for the inserts used in the connectors on the side of my mainframe?
The mainframe uses male inserts for the thermocouple connectors, D-M-E replacement part number RPM0072, and it uses female inserts for the power connectors, D-M-E replacement part number RPM0073.
