Nexus® 1262/1272 Socket Meter Quick Start

Hardware Installation:

The Nexus® 1262/1272 Socket meter can be mounted outside or in an enclosed and protected environment, such as in a
switchgear cabinet.
• Examine the labels to verify that the meter you are installing is, in fact, the correct form factor and service type.
Make sure that the socket and meter current class ratings are compatible.
• Make sure that all communication and auxiliary power wiring is accessible in case disconnection is required for
any reason.
• Before applying power to the meter, install batteries if not installed at the factory and check the connections if they
are installed. POWER MUST BE OFF TO INSTALL THE INTERNAL BATTERY! To install the Internal
Battery, remove the Internal Shroud and place the battery into the battery compartment with the + facing UP.
Replace the Internal Shroud. To install the Modem Battery, with the Outer Shroud on the meter, locate the battery
cable at the back of the meter and insert the cable connector into the cable. Use the velcro (peel and stick) to
attach the battery somewhere outside of the meter.
• Make sure that any communications wiring from the back of the meter is fed through the appropriate openings in
your socket to allow for clean connections with external devices.
• Insert the meter into the socket, making sure that the unit blades are firmly within the jaws of the socket.
• Connect external devices to the appropriate communications wiring, as shown below.
• Make sure the meter is functioning properly by running it through a test circuit.
NOTE: Refer to the Nexus® 1262/1272 Installation and Operation Manual on the enclosed CD for
information on Cable color, optional external displays, and optional external Output modules.
NOTE: The 1262/1272 Socket meter can also be inserted into an A-Base. See the dimensions shown on the next
