Power Cable Shielding
Power cables must be shielded, and the cable shield must connect to a ground.
Verify the separate brake wire shield connects to the overall chassis ground by looping back this brake
wire pair as shown in the figure Shielding of Brake Wires Within the Power Cable.
Shielding of Brake Wires Within the Power Cable
ATTENTION
High voltage can be present on the shields of a power cable, if the shields are not
grounded.
Verify there is a connection to ground for all shields in the power cable.
Failure to observe these safety procedures could result in personal injury or damage to
equipment.
Power cable contains brake wires with
separate ground shield.
Cable insulation is removed to expose
overall power cable shield.
Loop brake wires and signal shielding to contact
the overall power cable shield.
