GTNR terminal Narrow-head terminal
GTNR terminal brand: Suzhou Yuanli (The model varies with the brand.)
SG narrow-head terminal brand: Suzhou RCCN (The model varies with the brand.)
Note:
 If you select a cable model larger than a recommended model in the table, check whether the
wiring terminal width exceeds the allowed width in section 4.3.2 Terminal diagram of the main
circuit.
 If yes, select an SG narrow-head terminal and matching cable since an SG narrow-head terminal
has smaller width.
 The cables recommended for the main circuit can be used in scenarios where the ambient
temperature is lower than 40°C, the wiring distance is shorter than 100m, and the current is the
rated current.
 The terminals (+) and (-) are used by multiple VFDs to share the DC bus.
D.4.4 Cable arrangement
Motor cables must be arranged away from other cables. The motor cables of several inverters can be
arranged in parallel. It is recommended that you arrange the motor cables, input power cables, and
control cables separately in different trays. The output dU/dt of the inverters may increase
