Connection Power Stage Supply (CN1)

General

This product has a leakage current greater than 3.5 mA. If the protective ground connection is interrupted, a hazardous touch current may flow if the housing is touched.

DANGER
	INSUFFICIENT GROUNDING Use 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. Verify compliance with all local and national electrical code requirements as well as all other applicable regulations with respect to grounding of all equipment. Ground the drive system before applying voltage. Do not use conduits as protective ground conductors; use a protective ground conductor inside the conduit. Do not use cable shields as protective ground conductors. Failure to follow these instructions will result in death or serious injury.

DANGER

INSUFFICIENT GROUNDING

Use 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.
Verify compliance with all local and national electrical code requirements as well as all other applicable regulations with respect to grounding of all equipment.
Ground the drive system before applying voltage.
Do not use conduits as protective ground conductors; use a protective ground conductor inside the conduit.
Do not use cable shields as protective ground conductors.

Failure to follow these instructions will result in death or serious injury.

WARNING
	INSUFFICIENT PROTECTION AGAINST OVERCURRENT Use the external fuses specified in section "Technical data". Do not connect the product to a supply mains whose short-circuit current rating (SCCR) exceeds the value specified in the section "Technical Data". Failure to follow these instructions can result in death, serious injury, or equipment damage.

WARNING
	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 drive, verify the approved mains types, see Power Stage Data - General.

Prerequisites for Connecting the Power Stage Supply

Note the following information:

Three-phase drives may only be connected and operated via three phases.
Use upstream mains fuses.
If 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 drive exceeds 200 mm (7.87 in).
See section Conditions for UL 508C and CSA for a UL-compliant design.
