Quick Start Up for Nexus®Type S Meters
The Nexus® 1262/1272 Multiparameter Socket Meter can be
installed in three ways: Type S Meter, Type A Meter (on
an A Base) and Type Z Meter (in a Switchboard case).
This Quick Start Guide is meant to give the field technician
the basic steps for installation of the Type S Meter. Steps are
detailed in later chapters of this manual.
1.1:
Start-U U p and Bench Check
Power Up and Bench Check saves field time.
1.1.1: Meters with Auxiliary Power
If the meter has an Auxiliary Power cable
(Fig. 1.2), apply appropriate power to the
2 leads of the power cable.
Meter information scrolls on the display.
1.1.2: Meters without Auxiliary Power
To energize meters without Auxiliary Power,
apply appropriate power to the voltage
terminals of the meter. Terminals vary by
Meter Form. The Nexus® 1272 Meter Form
(FM 9S, 36S, 39S or 45S) is shown in the
white block under the display (Fig. 1.1).
See Figures 1.3 & 1.4 to determine terminals.
For Form 9S, 36S and 39S meters, connect
appropriate power to the one of the three
left most and to the right most voltage
terminals (center row of smaller terminals).
They are small, bold terminals in Figure 1.3.
(The large terminals are current
terminals for these Forms.)
NOTE: Form 39S uses the
same voltage terminals but
the current terminals differ.
Form 45S uses large terminals.
When the meter is energized,
the display lights up and
meter information scrolls on
the display. This completes a
95% test of meter functionality.
