INTRODUCTION Page 5 It is the intent of this manual to provide a guide for the installation of Toshiba medium voltage control components in NEMA Class E controllers manufactured by original equipment manufacturers (OEMs). This manual consists of a section of general safety instructions and is marked throughout with warning symbols.
Each JK Series OEM power cell is a modular unit containing a vacuum contactor, isolation switch, power fuse clips and other basic components necessary for the OEM to construct an AC general-purpose NEMA Class E medium voltage controller.

GENERAL DESCRIPTION Page 7 POWER CELLS WITH FIXED-TYPE CONTACTORS - MAJOR COMPONENTS A. Isolation Switch (Fig. 3) Power is switched on and off by a fixed- mounted, externally operated, three-pole isolation switch. When the switch is in the OFF position, incoming power is isolated from the power cell interior by an automatic shutter.

GENERAL DESCRIPTION Page 8 D. Interlocks – Mechanical The isolation switch is mechanically interlocked with the vacuum contactor and the compartment door. Three separate interlocks are provided, as described below. a. Door Interlock Bracket A door interlock bracket is provided to prevent opening closing medium...

GENERAL DESCRIPTION Page 10 POWER CELLS WITH WITHDRAWABLE TYPE CONTACTORS - MAJOR COMPONENTS A. Isolation Switch (Fig. 10) The isolation switch is the same design as that used for the fixed-type contactor, except in this configuration the switch accepts a direct connection from the line stabs of the removable contactor carriage.

GENERAL DESCRIPTION Page 11 C. Service Drawer (Fig. 12) The withdrawable contactor carriage is moved in and out of the power cell on a built-in slide-out service drawer. The drawer has four locating pins on top of it. When the contactor carriage is placed on the drawer, these pins engage four holes in the bottom of the carriage, which serve to align it properly.

INSTALLATION Page 18 MAIN CIRCUIT CABLING Cables which connect to the power cell should be routed to avoid interference with sharp edges and moving parts. Minimum bending radius for the type of cable used should be observed. Power cables should be braced and/or laced to withstand short-circuit forces wherever such cables are unsupported.
The medium two-high stacking arrangements voltage compartment door cannot be closed requires the use of a Toshiba JK lifting unless the release lever is pushed in. A device. mechanical interlock prevents the isolation switch from being closed unless the medium Manually lifting heavy voltage door is closed.
