Precautions
General Precautions
The following are warnings relating to the installation of the EC-BOS-8
UUKL option module.
•
Remove all power to the EC-BOS-8 UUKL before
attaching (plug in) or detaching (unplug) any option
module, to prevent possible equipment damage.
•
Removal of the EC-BOS-8 UUKL's cover is not
required. No configurable or user-serviceable items
(such as jumpers or a battery) are inside the option
module.
Static Discharge Precautions
Static charges produce voltages high enough to damage electronic
components. The microprocessors and associated circuitry within the
devices are sensitive to static discharge.
•
Work in a static-free area.
•
Discharge

accumulated. Discharge static electricity by touching a
known, securely grounded object.
Mounting
Mounting the EC-BOS-8 UUKL and all option modules on a 35mm wide
DIN rail is recommended. Mounting on a DIN rail ensures accurate
alignment of connectors between all modules. Tabs on the EC-BOS-8
UUKL or module can be used for panel mounting as an alternate to DIN
rail mounting.
