General safety recommendations

•
Keep the router and installation tools away from walk areas.
•
Place the router in a dry and flat location and make sure anti-slip measures are in place.
•
Remove all external interface cables and power cords before moving the router.

Electricity safety

•
Locate the power switch of the power source before installation. Shut off the power
immediately if an accident occurs.
•
Make sure the router is reliably grounded.
•
Connect the interface cables correctly.
•
Use an uninterrupted power supply (UPS).
•
Always make sure the power has been disconnected during installation or replacement.

ESD prevention

WARNING!
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between a human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the router and the floor are reliably grounded.
•
Keep the equipment room clean to reduce the negative effects of dusts and particles.
•
Maintain the humidity and temperature levels in the acceptable range.
•
Always wear an ESD wrist strap. Make sure the wrist strap makes good skin contact and is
reliably grounded.
No ESD wrist strap is provided with the router. Prepare it yourself.
To attach an ESD wrist strap:
1. Wear the wrist strap on your wrist.
2. Lock the wrist strap tight around your wrist to maintain good contact with the skin.
3. Secure the wrist strap lock and the alligator clip lock together.
4. Attach the alligator clip to the rack or workbench where the router is installed.
