Page 6: Installation
Installation Access to Interior Step 1 TO OPEN DOORS: Access to the interior of S&C Pad-Mounted Gear is controlled by the S&C Penta-Latch® Mechanism, which must be opened with a pentahead socket wrench or tool except when hexhead actuators (Catalog Number Suffix “-B1” or “-B2”) are specified . - Page 7 Installation TO CLOSE DOORS: Close the left-hand door, where applicable, and secure it with the latch by rotating the latch downward over the stop on the outer edge of the door . See Figure 3 . The right-hand door of double-door models of pad-mounted gear is equipped with the Penta-Latch Mechanism which latches automatically when the door is closed .

Page 8: Placement
Installation Placement Step 2 At the installation site, remove all separately packaged components shipped within the pad-mounted gear enclosure, including the steel deflectors . Two-compartment models are furnished with two large deflectors; four-compartment models are furnished with four large deflectors and two small deflectors . Set these items aside in a protected area . - Page 9 Installation If excess lengths of direct-buried cable are to be fed into the termination compartments as the unit is lowered, special attention must be paid to the cable position in the fuse termination compartments. Open the doors and secure them with the door holders, to allow the cable to be fed over the door stiles .
- Page 10 Installation After mounting the enclosure to the mounting pad, the deflectors are to be assembled to the unit . First, bolt one of the large deflectors to the bottom of a switch or fuse compart- ment frame using the supplied B\zn-inch serrated nuts . Refer to Figures 6, 7, and 8 . Repeat for the other compartment(s) .
- Page 11 Installation On four-compartment models, install the two small deflectors . Refer to Figure 9 . Each small deflector is installed behind the two large deflectors . Then bolt the small deflector into place using the supplied B\zn-inch serrated nuts . Confirm that the complete deflector assembly installation matches Figure 7 on page 10 .

Page 12: Cable Terminations
Installation Cable Terminations Step 3 Ç DANGER Before energizing the gear, replace the shipping caps on all bushings and bushing wells with elbows or insulated protective covers or plugs . Failure to replace the shipping caps can result in a flashover and serious personal injury or death. Switch terminals are equipped with 600-ampere-rated bushings, and fuse terminals are equipped with 200ampere-rated bushing wells . -
