Installing Cables
NOTE
This document uses the dual-input top cable routing and single-input bottom cable routing as
examples. Cable connections for other scenarios are similar.
NOTICE
1. Ensure that all circuit breakers, including upstream output circuit breakers, are switched to OFF
before connecting cables.
2. The PDC ground cable is secured to the equipment room ground bar. The resistance between
the PDC ground cable and the equipment room ground bar is less than 0.1 ohm.
3. The N and PE cables are bound separately from the L1/L2/L3 or L cables for each circuit
breaker. Cables are converged at the beam and bound in groups by cable ties.
