Figure 11: Installing a Three-Input 240-A Power Supply
Replacing the T640 Cable Restraint on a Three-Input 240-A Power Supply
Each three-input 240-A power supply is shipped with the standard cable restraint,
as shown in “Standard Cable Restraint on a Three-Input 240-A Power Supply” on
page 13. 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 “Optional Cable Restraint on a Three-Input 240-A
Power Supply” on page 14) 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.
