Ratings Input terminals (top lugs on CBA) are marked L1, L2, and L3 for the source
connections. Output terminal blocks are marked X1, X2, and X3 for the load
connections (See
Figure 5 ). In 4-wire models only, connect both input and
output N conductors to the NEUTRAL bus bar. Do not connect to the
NEUTRAL bus bar in 3-wire models. Replace all shields and covers when wiring
is completed. The doors must be closed and latched securely.

• Input/Output mechanical lugs accept AWG 4 to 350 kcmil [25 to 150 mm
2
] conductors. Tighten lugs to 250 lb-in [28.2
N-m]. Lugs require 5/16” hex key tool for installation.
• Output lugs are mounted on threaded studs and may be removed if desired. Studs are 3/8” [9.525mm] diameter and
nuts should be torqued to 192 lb-in [21.7 N-m].
• NEUTRAL Bus and Ground Bus are provided with 3/8”-16 threaded studs (9.525mm diameter). Tighten nuts to 25 lb-ft
(300 lb-in) [33.9 N-m].
WARNING: The HC-DySC must be safety-grounded according to the National
Electrical Code. In addition, all local, state, and federal regulations applicable to
the installation of electrical systems as well as accident prevention regulations
must be strictly observed
