Making Power Connections
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 NV6257 power supply 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.
Connecting Power to the NV6257 and the Router
The NV8256-Plus uses both power connections on the NV6257. To make this connection, NVI-
SION provides two power cables (WC0085-00).
How to Connect Power:
1 Locate the power cords, PS6000 power supply modules, and cables supplied by NVISION.
2 If not already removed, remove all PS6000 power supply modules.
3 Facing the rear of the NV6257, using one of the two power supply cables (WC0085-00), con-
nect to ‘Output Power 1’, as shown in Figure 3-1.
Caution Make power connections between the router and NV6257 before connecting the
NV6257 to an AC power source. Insert PS6000 power supply modules after con-
necting the NV6257 to an AC power source.
Connecting to AC power before the router is connected, or after PS6000 modules
are installed, may result in an electric shock.
