Installation Precautions
Observe the following precautions when installing
the ETUs to avoid static electricity damage to
hardware or exposure to hazardous voltages.
The ETUs used in this system make extensive use of CMOS
technology that is very susceptible to static; 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.
When carrying an ETU be sure to keep it in a conductive
polyethylene bag to prevent damage due to static electricity.
When handling an ETU the installer must wear a grounded
wrist strap to protect the ETU from static electricity.
When inserting or removing an ETU, be sure the wrist strap is
connected to the Frame Ground Terminal on the KSU. Refer
