Power Cable Shielding
HPK-Series motors with brakes integrate the brake signals (BR+ and BR-) with the 380…460V
power at the terminal block. The separate shield surrounding the brake signals must be grounded
to the overall system ground. To properly ground the brake ground shield, or any separately
shielded signal, follow these wiring guidelines.
Verify each cable shield connects to the overall chassis ground by routing as shown in diagram.
Clamp all shields together at the power cable (chassis) ground connection on the drive.
Power Cable Shielding
ATTENTION: High voltage can be present on the shields of a power cable, if
the shields are not grounded.
Verify that there is a connection to ground for each shield in the power cable.
Failure to observe these safety procedures could result in personal injury or
damage to equipment.
