Installation Precautions

Observe the following precautions when installing the
ETUs to avoid static electricity damage to hardware or
exposure to hazardous voltages.
CMOS technology that is very susceptible to static is extensively used in
the ETUs in this system; therefore, extreme care must be taken to avoid
static discharge when handling ETUs.
Make all switch setting changes on the ETU before inserting it in the
KSU.
When installed, the component side of all ETUs must face the left side of
the KSU. Ejector tabs are always on top. Refer to
the ETU into the
