5.2 Meter Board Connections (continued)
3. External Switch Mechanism/In-Line Fuse Installation
To ensure a safe installation, the Class 4000/4100 requires an external
switch mechanism, such as a circuit breaker (max. 15 amps), be
installed to the Class 4000/4100 MAINS input wiring. The switch
mechanism must be installed in close proximity to the Class 4000/4100
and easily reachable for the operator. This device must also be marked
as the disconnecting device for the Class 4000/4100. Install 1/10 amp
Slow Activation inline fuses with the suitable voltage rating for
each conductor Phase at the MAINS input to the meter. The fuses must
be labeled to indicate voltage and current rating as well as element
characteristics. The fuse element must be slow activating type.
5.3 Current Sensor Installation & Wiring
The meter board contains two plug-in connectors located at the bottom center
of the board, TB2 and TB3. (See Figure 1.1.1) Connector TB2 is the input for
Phase A, and TB3 is the input for Phase B.
The Class 4000/4100 meter can be used with two types of current sensors:
1. Split-core current sensor. This sensor opens so that it can be attached
around the circuit being monitored without interrupting power. Unless
otherwise specifi ed, all Class 4000/4100 meters are supplied with this
sensor type.
2. Solid-core current sensor. This sensor does not open and requires the
monitored conductor to be removed from the circuit to install the current
sensor. This type is only supplied when specifi ed at time of order.
5.3.1 Installing the Split-Core Current Sensor Assembly
1. Each phase being monitored will require one two-piece current sensor
assembly. Open the two-piece current sensor assembly by releasing
the nylon clamp using a fl athead screwdriver.
