Honeywell 500-XCL5010 Furnace User Manual


 
EXCEL 500/600 INSTALLATION INSTRUCTIONS
Type XW569 13 in. (330 mm) long (for housings one
above the other)
CAUTION
Incorrectly inserted bus cables can destroy the
modules installed.
The internal bus begins at the first housing, containing the
power supply and computer modules, and ends at the last
housing.
The protective bus connection covers must be removed.
Fig. 5. Removal of bus connection cover
The overall internal bus length (bus cable and bus in the
housings) must not exceed 6 ft (2m).
Bus cables must be routed at least 2 in. (50 mm) away from
power cables to prevent possible inductive and capacitive
interference.
Module Locations (not XCL5010)
Each housing has four plug-in module locations.

Coding the Terminal Block (not XCL5010)
The terminal block is coded with pins to prevent mixing the
module types during commissioning or servicing. Mixing the
modules can damage them.
You can code the terminal block by inserting pins into
designated location holes on the terminal block in the base.
Fig. 7. Inserting the code pin in the terminal block
Table 2 shows the coding pin positions for the individual
module types:
