MULTI-DRIVE PROCESS LINE CABINETS

MCC-style 90" high relay sections are available with gro up-mounted Alti var 58 TRX AC d rives . All drives
are installed together in one cabinet instead of individual plug-on MCC units. Thi s allows grea ter density
and reduces floor space over traditional MCC unit construction. Drives are not isolated fro m each other,
and are fed from one circuit breaker disconnect.
Multi-drive process line cabinets are suited for process line applications where a fault or maintenance
of one drive on the process requires the entire process to shut down. Applications in automotive, food
and beverage, pharmaceutical, and other process industries using multiple drives for a single process
machine are candidates for this product. Pre-engineered, pre-assembled packaging saves third-party
assembly labor and commission time on simple installations.
An efficient cooling system and current-limiting fuses provide f actory-assured, UL-certified performance
to UL 845 MCC standards. Each drive has a uniquely numbered door-mounted keypad for easy
monitoring and setup. Drives can be set up with a program from a single keypad if preferred.
Only drives rated 480 Vac are available and are pre-programmed for constant torque applications. No
control pilot devices or 120 Vac control power is a vailable, making this package more suited for simple
remote control schemes or for further integration in the field. Packages are d esi gne d for NEMA Type 1
environments. Horizontal bus is provided for splicing to existing Model 5 or 6 MCC sections or an
additional MCC incoming line section.
Any number of drives up to the maximum indicated in the tab le belo w ma y b e install ed in the m ulti-driv e
process line cabinet. However, all drives in the same cabinet must be of the same rating. Panels for
adding the maximum number of drives will be installed.
