The terminal screw dimensions for all L200

 inverters are listed in table below. This 

information is useful in sizing spade lug or ring lug connectors for wire terminations.

CAUTION: Fasten the screws with the specified fastening torque in the table below. 
Check for any loosening of screws. Otherwise, there is the danger of fire.

When connecting wiring, use the tightening torque listed in the following table to safely 
attach wiring to the connectors.

Step 6: In this step, you will connect 
wiring to the input of the inverter. First, 
you must determine whether the inverter 
model you have requires three-phase 
power only, or if it can accept either 
single-phase or three-phase power. All 
models have the same power connector 
terminals [R/L1], [S/L2], and [T/L3]. 
So, you must refer to the specifications 
label (on the side of the inverter) for 
the acceptable power source types! For 
inverters that can accept single-phase 
power and are connected that way, 
terminal [S/L2] will remain uncon-
nected.

The examples to the right show single-
phase and 3-phase input wiring. Note the 
use of ring lug connectors for a secure connection.
