#1, connect the module
installed. Any harness connections that remain after all
installed modules are connected
secured above the last module.
Danger - Harness must be secured such that it
cannot come into contact with primary (line volt-
age) AC wiring.

last Module Interface. If any of the Module Interfaces
are located more than 15.25 meters (50 ft.) from the
processor, the last Module Interface on the chain must
utilize a terminator across
nators that are included with the processor may be
used for this application (see Figure 3). If LT-I termina-
tors are not available, a 1/4 Watt resistor
and 150 ohms may be placed from terminal 3 to termi-
nal 4 to provide termination. Termination at the proces-
sor end of the chain is included on the processor board
so an LT-I is not required.

the terminal blocks as shown in Figure 3. The manu-
al override scene (as programmed in the HomeWorks.
InteractiveTM Utility) is activated for all modules connect-
ed to the Module Interface by closing the manual over-
ride switch wired between the two terminals (see Figure
3). A toggle switch is provided with each HomeWorkse
InteractiveTM Processor for this purpose. For maximum
reliability, group Module Interfaces on a single switch.
This arrangement should have the switch and all of the
Module Interfaces wired in parallel (see Figure 3). Note:
Proper polarity must be maintained across all units. For
manual override cable runs less than 300m (1000 feet)
connected to a single Module Interface, 0.5—1.5mm2
(16—24 AWG) wiring can be used. For manual override
cable runs exceeding 300m (1000 feet) or those con-
nected to multiple Module Interfaces, 1.0—1.5mm2
(16—18 AWG) wiring must be used. If the installer
chooses to use their own switch, the switch must be
rated for switching at least 50mA @ 28VDC. For switch-
ing multiple Module Interfaces the switch must be rated
for switching the sum of the current for all of the Module
Interfaces connected (e.g., 6 Module Interfaces wired to
a single override switch would require a switch rated for
300mA @ 28VDC).
