Connecting the Router to Power
Connecting the Router to Power
The NV5128 uses the PS6000 power supply module. The NV5128 requires a minimum of one
PS6000 power supply module (plus one optional modules for redundancy). The router requires two
AC power cords.
The NV5128 has a ground lug on the back of the router. Whether to ground or not is optional and
failure to connect the ground does not affect normal operation. However, grounding helps protect
you and your equipment in case of a power anomaly such as a lightning strike.
Power Supply Monitor and Alarms Connections
The NV5128 has a ‘Power Supply Alarm’ connection, located on the rear of the frame. The con-
nection carries alarm and temperature signals to the router. This connection is connected at the
same time the power connections are made.
Power Cords and Branch Circuits
For added protection in the event of a mains power failure, it is recommended that each power cord
connected to the router frame be connected to a separate branch circuit. A wire bail can be used to
hold the power cable in place to reduce the possibility of an accidental disconnect.
The power cords are the only means of disconnecting AC power. Clearly mark the line side power
connection with its function so that in the event of an emergency, power can be disconnected
quickly.
Making Power Connections
Important! Be sure to connect to AC power before installing PS6000 power supply modules. Con-
necting to AC power after PS6000 modules are installed may result in an electric shock.
How to connect the router to a power source
1 Locate the power cords and PS6000 power supply modules.
2 If not already removed, facing the front of the router, remove all PS6000 power supply mod-
ules, as shown in Figure 3-1.
