• Place any removed memory card on an antistatic surface or in a static shielding bag. If the card will be
returned to the factory, immediately place it in a static shielding bag.
• Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages on
the body only; ESD voltages on clothing can still cause damage.
• Do not remove the wrist strap until the installation is complete.
Cabling Guidelines
Follow these guidelines for using cables with the router:
• Position cables so that they do not place strain on the router connectors.
• Organize cables into bundles when necessary to avoid intertwining.
Inspect cables to ensure adequate routing and bend radius.
• Install cable ties that comply with your site requirements.
Connecting to AC Power
When connecting the router to AC power, you must ensure that the following conditions are met:
• AC power can be readily and conveniently removed from the router. The power should not be removed
by disconnecting the AC power connector on the unit. It should be removed by disabling AC power at
the power circuit.
The plug-socket combination must be accessible at all times, because it serves
as the main disconnecting device. Statement 1019
Warning
Before connecting or disconnecting the power cord, remove AC power from the
power cord using a suitable service disconnect.
Caution
• Protect AC power plugs and AC receptacles from water and other outdoor elements. You can use a
UL-listed waterproofing enclosure suitable for covering the AC receptacle and AC power plug that
supplies power to the unit, as described in Article 406 of the National Electric Code (NEC).
• When you install the unit outdoors, or in a wet or damp location, the AC branch circuit that powers the
unit should have ground fault protection (GFCI), as required by Article 210 of the NEC.
• If the power cord goes through a metal cover, a bushing should be installed to prevent fraying of the
cord. When using a strain relief bushing, you should follow these recommendations:
• Use properly sized parts
• Use bushings that are safety certified
• Use parts that are suitable for outdoor installation
