2 INSTALLATION
A broad range of 469 applications are available. Although it is not possible to present typical connections for all
possible schemes, this section will cover the interconnections of instrument transformer inputs, other inputs,
outputs, communications, and grounding. See Figure 2–9: TERMINAL LAYOUT on page 2–6 and Table 2–1:
469 TERMINAL LIST on page 2–7 for terminal arrangement.
The 469 control power must match the installed switching power supply. If the applied voltage
does not match, damage to the unit may occur!
CAUTION
The order code from the terminal label on the side of the drawout unit specifies the nominal control voltage as
one of the following:
LO:
20 to 60 V DC
20 to 48 V AC
Ensure applied control voltage and rated voltage on drawout case terminal label match. For example, the HI
power supply will work with any DC voltage from 90 to 300 V, or AC voltage from 70 to 265 V. The internal fuse
may blow if the applied voltage exceeds this range.
Extensive filtering and transient protection are built into the 469 to ensure proper operation in harsh industrial
environments. Transient energy must be conducted back to the source through the filter ground terminal. A
separate safety ground terminal is provided for hi-pot testing.
All grounds MUST be hooked up for normal operation regardless of control power supply
type.
