Terminal Dimensions And Torque Specs; Wire The Inverter Input To A Supply - Hitachi L200 Series Instruction Manual

Terminal Dimensions and Torque Specs

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.
Screw Tightening Torque
M2 0.2 N•m (max. 0.25 N•m) M3.5
M3 0.5 N•m (max. 0.6 N•m)

Wire the Inverter Input to a Supply

Step 6: In this step, you will connect wiring to the
6
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 unconnected.
The wiring example to the right shows an L200
inverter wired for 3-phase input. Note the use of
ring lug connectors for a secure connection.
