1. What’s inside the bundle?
Each 1756‑PBR2 kit contains: 2 × 1756‑PB75R supplies, 2 × 1756‑CPR2 cables, and 1 × 1756‑PSCA2 chassis adapter

Yes—models with a “K” suffix (e.g., 1756‑PBR2K) are conformal-coated for high-humidity or harsh environments.
3. What mounting space is needed?
Allow at least 12.7 cm (5") clearance on the left and underside of the redundant supplies for cable routing in Series C chassis.
4. What do I do if one supply fails?
The redundant design ensures one supply maintains power; the other recovers as it becomes available.
The PSCA2 and CPR2 cables manage smooth transitions and signaling of impending power loss .
