Conditions for UL applications
Note
Conditions for UL applications
• Only use copper cables rated for 75 °C.
• For line and motor connections, only use UL-approved ring cable lugs (ZMVV) that are
certified for the particular voltage. The permissible current-carrying capacity of the cable
(routing type B2) must be at least 125 % of the input or output current.

DRIVE-CLiQ signal cables and MOTION-CONNECT power cables
DRIVE-CLiQ signal cable
The various options for connecting a direct measuring system with DRIVE-CLiQ and M12 plug via
MOTION-CONNECT cables to a DRIVE-CLiQ component are described in Chapter "Connection
system" of the SINAMICS S120 Equipment Manual Booksize Power Units (

8.9.3
Current-carrying capacity and derating factors for power cables and signal
cables
The current-carrying capacity of PVC/PUR-insulated copper cables is specified for routing types
B1, B2 and C under continuous operating conditions in the table below with reference to an
ambient air temperature of 40°C. You must calculate the current-carrying capacity for deviating
ambient temperatures. To do this, use the derating factor listed in the table below.
