HONEYWELL EXCEL 5000 OPEN SYSTEM
BEFORE INSTALLATION
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
Digital Wall Module (DWM) wiring can be sized from 16 to 22
2
AWG (1.5 to 0.34 mm
), depending on the application. The
max. length of wire from a device to a DWM is 164 ft (50 m).
Twisted pair wire is recommended for wire runs longer than
100 ft (30.5 m).
CAUTION
EMI Noise Introduction.
Risk of erratic system operation.
Keep wiring at least one ft (305 mm) away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels. During
installations, try to avoid areas of high EMI noise.
Run DWM wiring separately from 50 Vac or greater
power wiring.
WARNING / CAUTION
Risk of electric shock or equipment damage!
Do not touch any live parts inside the DWM housing.
►
Disconnect the power supply before making connections
►
to or removing connections from the DWM's terminals.
Do not reconnect the power supply until you have com-
►
pleted the installation.
If the DWM is powered via terminal 8 and connected to
►
earth ground, then the cable must be shielded.
Observe precautions for handling electrostatic sensitive
►
devices.

NOTE: A software module (ModAL module GNRSC02A) is
available to adapt the DWM to the respective Excel
20, 50, 100, 500, 600, or 800 controller, making any
further configuring obsolete. Contact your local
Honeywell distributor for further details.
DWM DISASSEMBLY
The T7560A,B,C comes packed with a sub-base that mounts
separately for ease of installation. The cover is fixed by a
latch on the underside of the unit. Remove the cover as
shown in Fig. 1 (T7560A,B) or Fig. 2 (T7560C):
1. Insert the tip of an awl or a similar narrow, pointed object
into the small hole in the latch (T7560A,B) or simply
depress the latch by hand (T7560C).
2. Pry off the cover.
