Connecting The Power Cord; Connecting The Ac-Input Power Cord - H3C AR 46-20 Installation Manual

H3C AR 46 Series Routers Installation Manual
Connect the PGND to the earth ground using a PGND cable with a grounding
resistance less than 5-ohm. If you install the chassis in a 19-inch standard rack, you
must also ground the rack.
Warning:
Lightning strikes can damage your router and even the connected devices. For secure
lightning protection, make sure that your router has a good ground connection when it
is operating.

3.6 Connecting the Power Cord

The AR 46 series is available with both AC-powered and DC-powered units. Except for
PSU type, they have the same features and functions.

3.6.1 Connecting the AC-Input Power Cord

I. AC-input power supply
AC input range: 100 VAC to 240 VAC, 50 to 60 Hz.

II. AC power socket (recommended)
You are recommended to use a three-terminal single-phase power socket with ground
contact, which must be grounded reliably. Normally, the ground contact of the power
supply system in a building was buried during construction and cabling. Still, before
connecting the AC-input power cord, you must make sure that the power supply of the
building is well grounded.
