FULL WIRING SHEET 8 — BED ENCLOSURES (§6.5.1, rev 3.54)
Waterproof CONTROL BOX (logic only) · SEPARATE power section · everything enters through 3 glands + 1 breather
glands on the BOTTOM/SIDE face, never the lid · drip loop below each gland · match gland to cable OD

POWER SECTION — SEPARATE box/bracket
high current stays OUT of the control box:
big holes · heat · noise beside data
