Materials and Tools Required

Suitable tools and fasteners for mounting the unit, attaching it to an already mounted EC-BOS. DIN-rail mounting of the EC-BOS and all its option mod-
ules is recommended.

Precautions
The following are warnings relating to the installation of the EC-BOS option module.
£ Remove all power to the EC-BOS before attaching (plug in) or detaching (unplug) any option module, to prevent possible
equipment damage.
£
Removal of the EC-BOS's cover is not required. No configurable or user-serviceable items (such as jumpers or a bat-
tery) 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 any static electricity you may have accumulated. Discharge static electricity by touching a known, securely
grounded object.
Mounting
Mounting the EC-BOS and all option modules on a 35mm wide DIN rail is recommended. Mounting on a DIN rail ensures accurate alignment of connec-
tors between all modules. Tabs on the EC-BOS or module can be used for panel mounting as an alternate to DIN rail mounting.
£ Remove all power to the EC-BOS before installing or removing option modules. See
