6. A fuse, internal to the three-phase power module, is
located in series with each of the 3 incoming AC
lines. The fuses are 3/4 amp, 600 volt, 200kA
interrupting rating. These fuses are internal to the
power module. You can access them by removing
the three screws holding the cover in place (see
Figures 2.1 and 2.2).
Required:
The voltage terminal block has four
terminals for wiring (one is neutral). The neutral
must be connected to Neutral or Ground depending
on your configuration.
7. The communication port, located on the lower right
chassis, is designed to connect with the optional
communication module (a PONI module). See
Section 2.1.4 for a detailed description.
8. The discrete input can be configured to be either a
reset input or a sync pulse input. The input is
activated by a contact closure across terminal block
contacts 1 and 2. See Section 5.15.1 (p.34) for
configuring this input.
9. Watt-hour Pulse. The Watt-hour pulse initiator is a
set of contacts that completes a circuit and sends a
