Each three-input 240-A power supply is shipped with the standard cable restraint shown
in Figure 130 on page 284. Two optional cable restraints are shipped in the accessory box.
If your DC power cables are too large or inflexible to fit into the standard cable restraint,
we recommend that you remove the standard cable restraint and install the optional
cable restraint (see Figure 131 on page 284) on each three-input 240-A power supply.
NOTE: Before you remove a chassis from a rack or cabinet, you must remove
the optional cable restraint from the three-input 240-A power supply.
