An EMC filter is internal to the Z1000U Matrix drive and is standard on all Z1000U Matrix bypass packages. |
| Drive Input Circuit |
G
|
UL Type 1
UL Type 12
UL Type 3R |
For drive service switch that removes power from the drive. |
| 3-Contactor Bypass |
B
|
UL Type 1
UL Type 3R |
For a 3-contactor bypass that removes power from the drive. |
| Output Reactor |
K
|
UL Type 1
UL Type 3R |
No form of output impedance is normally required. A 5% load reactor, option (K), is available if additional output impedance is desired (usually for long lead-lengths or noise reduction). |
| Soft Start Bypass |
W
|
UL Type 1
UL Type 3R |
Provides a solid-state adjustable soft starter for use when switching to bypass mode. Option (W) provides a solid-state soft-starter with adjustable ramp to reduce mechanical system stress typically associated with across-the-line bypass motor starts. Select option (W) if the application cannot tolerate the mechanical load stress caused by across-the-line bypass motor starts. |
| Surge Suppressor |
2
|
UL Type 3R |
This option provides a degree of protection from ansient surges coming through the power line cables. Lightning strikes are the most common source of surges. |
| Space Heater |
