1. Foreword
This booklet provides information for the Medium Voltage (2.4 kV to 6.9 kV) SafeGear MCC Controller as described below.
All information in this booklet was current at the time of printing. All references in this booklet are determined from viewing the controller from the front.
DRAWOUT (REMOVABLE):
A drawout controller is a controller that may be removed from a cell without the unbolting of any connections or mounting supports. It utilizes specific interlock
devices that function according to ANSI standards, which allow for the safe removal of the device with minimal risk to personnel. It is intended for use in SafeGear
®
,
ADVANCETM, or abbreviated versions of ABB and OEM switchgear. It also contains plug-in primary and secondary disconnects with two physical ANSI operating
positions within the cell: Connected and Test /Disconnected. In the connected position both primary and secondary contacts shall be engaged. In the Test/
Disconnected position, primary contacts are separated from the bus contacts while the secondary contacts remain engaged to the controller to be tested. The
connection of secondary circuits shall be completely automatic, it shall not depend on operator interaction.
FIXED-MOUNT:
A Fixed-mount controller is intended to be mounted as a stationary device. It does not contain any racking related interlocks and/or primary leads. Primary
connections are hard bussed to the associated gear in which the controller is installed by the consumer. Secondary wiring is terminated on a 5 foot length of wire
from the compartment to secondary plugs that are the same as the draw-out versions. Plugs and associated pins can be purchased for plug in connection or the
wires may be cut to provide direct connections. The fixed mount version must be provided with the plugs in this manner to meet UL listing and to insure proper
testing of the controller. The customer is responsible for any damage to the controller that is due to mis-wiring of the controller.
