4.
DO NOT
use any part of the DMA or the mounting
bracket of the DMK/6 assembly as a lever to

Wiring the DMA
1. Remove all power supplies.
2. Use minimum AWG #16 class 1 wiring for all terminals.

Terminal Block for DMA
WIRING
5. The cover has an intergrated protective barrier that
physically separates the wiring from the moving
adjustment switches and cams. Wiring must be
properly routed so that the cover can be installed.
6. For terminals 8 and 10, use properly sheilded wires, that
are grounded on both sides, and run through conduit
containing only low voltage (24V) wiring.
