Section 1: General informa-
tion about the updated drawout
secondary terminal blocks
These instructions detail the upgrade process from
the Digitrip drawout secondary terminal blocks
to the PXR drawout secondary terminal blocks.
The number of terminal blocks and contact points
change slightly from the Digitrip design to the
PXR design (see Table 1). The number of terminal
blocks mounted depends on a number of consid-
erations, such as whether the circuit breaker is
electrically or manually operated and how many
features are required.
A number of graphics in this instruction leaflet use
N ote:
the standard frame (IZM32) circuit breaker for illustrative
purposes only. The double frame circuit breaker (IZM63)
is handled in a similar fashion. Some components, such
as the trip unit, are not shown for clarity.
