Working Inside the WAVE-574 with the Power On
The WAVE-574 is designed to operate safely with the cover removed for short
periods (less than 30 minutes). You might need to remove the cover while the
power is on, for example, to observe the diagnostic LEDs when troubleshooting.
When you work inside an appliance that is powered on, follow these guidelines:
•
Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts
before working inside the appliance; do not wear cuff links while you are
working inside the appliance.
• Do not allow your necktie or scarf to hang inside the appliance.
•
Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting
wristwatches.
•
Remove items from your shirt pocket (such as pens or pencils) that could fall
into the appliance as you lean over it.
•
Do not drop any metallic objects, such as paper clips, hairpins, or screws, into
the appliance.
•
Be aware that there are hazardous moving parts exposed inside the appliance
when the cover is removed.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside the appliance. To prevent
static damage, discharge static electricity from your body before you touch any of
your system’s electronic components. You can do so by touching an unpainted
metal surface on the chassis.
You can also take the following steps to prevent damage from electrostatic
discharge (ESD):
•
When unpacking a static-sensitive component from its shipping carton, do not
remove the component from the antistatic packing material until you are
ready to install the component in your system. Just before unwrapping the
antistatic packaging, be sure to discharge static electricity from your body.
•
When transporting a sensitive component, first place it in an antistatic
container or packaging.
