Electrical connection
8.3 System integration
Outer protective conductor or potential bonding conductor
Note
For 1FW328☐ and for 1FW3204-3* / 1FW3206-3* / 1FW3208-3*, there is an additional
connection point on the frame to connect an outer protective conductor or potential bonding
conductor.
Motor and cable protection
NOTICE
Damage due to cables being overloaded
If the electric power is transferred using several cables connected in parallel, then when
one cable fails, the other motor cables could be overloaded.
• Provide each individual cable with an overcurrent protection device.
Current-carrying capacity for power and signal cables
The current-carrying capacity of PVC/PUR-insulated copper cables is specified for routing
types B1, B2, C and E under continuous operating conditions in the table with reference to
an ambient air temperature of 40° C.
For other ambient temperatures, the values must be corrected by the factors from the Table
"Derating factors".
