|
INSUFFICIENT GROUNDING |
|
oUse a protective ground conductor with at least 10 mm2 (AWG 6) or two protective ground conductors with the cross section of the conductors supplying the power terminals. oVerify compliance with all local and national electrical code requirements as well as all other applicable regulations with respect to grounding of all equipment. oGround the drive system before applying voltage. oDo not use conduits as protective ground conductors; use a protective ground conductor inside the conduit. oDo not use cable shields as protective ground conductors. |
|
Failure to follow these instructions will result in death or serious injury. |
|
|
|
INSUFFICIENT PROTECTION AGAINST OVERCURRENT |
|
oUse the external fuses specified in "Technical data". oDo not connect the product to a supply mains whose short-circuit current rating (SCCR) exceeds the value specified in the chapter "Technical Data". |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |

|
INCORRECT MAINS VOLTAGE |
|
Verify that the product is approved for the mains voltage before applying power and configuring the product. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The products are intended for industrial use and may only be operated with a permanently installed connection.
Prior to connecting the device, verify the approved mains types, see chapter Power Stage Data - General.

Prerequisites for Connecting the Power Stage Supply
Note the following information:
oThree-phase devices may only be connected and operated via three phases.
oUse upstream mains fuses.
oIf you use an external mains filter, the mains cable must be shielded and grounded at both ends if the length between the external mains filter and the device exceeds 200 mm (7.87 in).
oSee page Conditions for UL 508C and CSA for a UL-compliant design.
