Mod
E301
ANSI #61 Enclosure paint
Provides option to configure enclosure paint to industry standard ANSI#61 light gray paint in lieu of ANSI #49 dark gray
Mod
E302
Free standing enclosure (1– 20 HP CT/1– 25 HP VT 460 VAC)
Converts all standard wall mounted enclosure configurations to a floor-mounted 90 in. high enclosure.
Mod
E303
Oversized enclosure (1– 50 HP CT/1– 60 HP VT 460 VAC)
Converts all standard wall and floor-mounted enclosures up one enclosure size.
Mod
E304
Barriered enclosure expansion
Uses Barriered enclosure for non-bypass drives controllers. Bypass space is configured with circuit breaker disconnect
and handle only.
Mod
E401
Dynamic braking resistors (Top mounted)
Provides dynamic braking resistor top mounted on the enclosure. Resistors are 10% duty cycle rated. Overload
protection for externally mounted dynamic braking resistor is mounted inside the drive controller enclosure.
Note: Drives rated 125–500 hp @ 460 V do not provide internal dynamic braking transistors. Consult factory
Mod
E402
Top mounted motor protecting filter
Provides a factory mounted and wired dv/dt filter on the drive output for long motor lead lengths considerations in
excess of our published guidelines, up to 1000 feet.
Mod
E403
NEMA rated contactors
Provides NEMA rated contactors for isolation and bypass configuration in lieu of the IEC rated contactors.
Note: Devices rated 250–400 hp @ 460 V use NEMA rated contactors as standard.
Mod
E404
380V/50Hz system configuration
Provides device modifications to control power transformer, power contactors (when provided) and firmware
configuration to 380 V/50 Hz utilization voltage and alters nameplate rating to reflect “KW” in lieu of hp ratings.
Note: CE Marking not available
Mod
E405
Transient Voltage Surge Suppressor
Provides supplementary surge protection using a Class 1310 TVSS XF Series Transient Voltage Surge Suppressor
hard-wired and factory mounted.
