WARNING
Before you connect a voltage source, observe the
following power supply voltage guidelines.
Otherwise, you will void your warranty if the wrong
voltage is applied.
c
Be sure the voltage source is within the permitted
ranges shown above. Otherwise, your modem and
any attached devices may be damaged.
c
Customer-supplied cables must be suitable for the
site environmental conditions.
c
Screw terminals on the power interface accept 24 to
16 AWG. However, surge protection is guaranteed
only if the ground wire is greater than 18 AWG and
if there is a solidly earthed ground connection.
c
Be sure the power source is not controlled by a wall
switch, which can be inadvertently turned off,
shutting off power to the modem.
