Vertiv | NetSure 7100 Series -48V DC Power System Installation Manual (IM582127000) | Rev. BB
Connections to AC Input Termination Assemblies (582127000 List 40, 41, 42, 43) (For System Mounted
in an Enclosure)
The enclosure provides conduit plates attached to the top of the enclosure. Two types of conduit plates are
available. Select and install the conduit plate appropriate for your application. See “AC Input Conduit Options”
on page 17. It is recommended that AC input wiring be provided to all rectifier mounting positions, including
currently unused positions. This wiring will ease future installation of rectifiers to meet increased load
requirements.
NOTE!
A grounding conductor must be provided with each conduit.
Procedure
Refer to Figure 42, Figure 43, Figure 44, or Figure 45 as these procedures are performed.
Accessing Connections and Routing Wire
1. Ensure the proper conduit plates are attached to the top of the enclosure. See “AC Input Conduit
Options” on page 17.
2. Install conduit fittings as required in the conduit plates attached to the top of the enclosure. Plug
buttons are provided, and must be installed in the openings not being used.
3. Inside the distribution cabinet, remove the two AC input connector covers by first loosening the
fasteners that secure each of them.
4. Route wiring into the enclosure through the previously installed conduit fittings.
Making AC Input Connections
1. Make AC input connections as shown in Figure 42, Figure 43, Figure 44, or Figure 45. Connect each
wire by inserting the stripped end into the wire opening, and then tightening the screw. Torque
connections to value shown in the appropriate illustration.
NOTE!
Terminal blocks for a system with maximum possible rectifier shelves shown. Your system may
have fewer terminal blocks than shown.
Making Equipment Grounding Connections
NOTE!
Make equipment grounding connections to earth ground,
not
to the branch circuit neutral
conductor.
1. Connect equipment grounding leads to the frame ground studs using installer-provided ring lugs and
factory-supplied mounting hardware. Torque connections to value shown in the appropriate illustration.
Reinstalling Covers
1. After all AC input and equipment grounding connections have been made and checked, reinstall the two
AC input connector covers inside the distribution cabinet. Secure each by tightening the fasteners.
