Fig. 9. Transformer power wiring details for one W7760C
used in UL 1995 equipment (US only).
NOTES ON COMMUNICATIONS WIRING:
— When daisy chaining from one device to
another and using both sets of network screw
terminals on the W7760C, be aware that the
network is broken when the cover is unplugged.
If this is a problem, use one set of screw
terminals for both wire pairs.
— Do not bundle output wires with sensor, digital
input or communications LONWORKS® Bus
wires.
— Do not use different wire types or gauges on the
same LONWORKS® Bus segment. The step
change in line impedance characteristics may
cause unpredictable reflections on the
LONWORKS® Bus.
— In noisy (high EMI) environments, avoid wire
runs that are parallel to noisy power cables,
motor control centers, or lines containing
lighting dimmer switches; keep at least 3 in. (76
mm) of separation between noisy lines and the
LONWORKS® Bus cable.
— Each W7760C Plant Controller can support
three remote input/output (RIO) devices. For
more details on network topology rules, refer to
the E-Bus Wiring Guidelines, form 74-2865, or
see the W7760C System Engineering Guide,
form 74-3079.
— Make sure that neither of the LONWORKS®
network wires is grounded.
NOTE: If a 209541B Termination Module is required at the
plant controller, connect two of the three termination
module wires to the LONWORKS® network terminals.
Selecting the two appropriate wires depends on the
LONWORKS® network topology. For example, when
using a doubly terminated daisy-chained topology
with devices on either end of a LONWORKS® network
wire run, mount the termination module on the
appropriate terminals as shown in Fig. 10. Refer to
the E-Bus Wiring Guidelines, form 74-2865 and the
Excel 10 FTT Termination Module Installation
Instructions, form 95-7554.
