3.4.4 Wiring
Locate the parts according to figure 3-7 ~ 3-10.
AC voltage and current may bring hazard of electric shock and cause serious personal injury or
even death. Only well-trained and experienced person can exercise the following operation.
While mounting the wiring conduit, pay attention to the following precautions:
A. Cover the transfer switch to avoid unexpected enter of metal chips before mounting the
conduit.
B. If rigid tube is applied to connect the generator set and transfer switch, it is suggested to mount
flexible pipe between the rigid pipe and generator set to absorb vibration. Waste generated from
mounting may cause the equipment failure or damage.
Pay special attention not to have the drilling debris or filings into ATS, connection terminal block,
contactor or other parts. Additionally, pay attention not to damage the parts when using a
screwdriver.

A. Test the operation of generator set with generator set controller.
B. Shut off the generator set and cut off the negative terminal to avoid start.
Do cut off the battery of generator set (first cut off the negative wire) before wiring to prevent electric
shock caused by the start of generator which may cause serious personal injury or even death..
C. Current carrying capacity of the connection lead should be wide enough to bear the rated current
required by connection between transfer switch terminal and gird, load and generator set. Phase of
the grid and the generator set should be exactly the same (refer to Fig.3-15~3-18).
D. Connect the power cord to load output terminal.
