Wiring Details
See
on page 7 to locate connectors and other components on the T-600 controller.
Note
If biasing is needed for the controller's RS-485 base port, controller disassembly and reassembly is
needed. See
Make connections to the controller in the following order.
1.
Install any option cards (LON, RS-485, RS-232, etc.) in option slots 1 and 2. See
page 9 for a general procedure. For complete details, refer to the specific installation document
that shipped with the option card.
2.
Connect supplied earth grounding wires (with spade connector) from the earth ground lug on the T-600
and any accessory modules (if used) to a nearby earth grounding point. See
3.
Prepare power wiring (leave the unit powered off). See
for details.
4.
Connect communications cables. See
page 14 for ports available on the T-600
base unit. For ports on any installed option board (LON, RS-485, modem) see the specific mounting and
wiring guide for any additional details.
5.
If IO accessory modules are installed, connect the I/O wiring. Refer to the appropriate mounting and
wiring guide for complete details.
6.
Connect the backup battery to the T-600 battery connector, and apply power to the unit. See
Grounding
An earth ground spade lug (0.187") is provided on the base of the T-600 for connection to earth ground. For
maximum protection from electrostatic discharge or other forms of EMI, connect the supplied earth grounding
wire to this lug and a nearby earth ground (see
on page 12). Keep this wire as short as possible.
Power is provided for plug-in accessory modules through the 20-pin accessory connectors. However, you should
also connect the earth ground spade lug of
each accessory module
to ground in the same manner.
Power Wiring
The T-600 controller must be powered by an approved 15 Vdc power source. This can be
either
1
a DIN-mount
24Vac/dc-powered module (NPB-PWR), a DIN-mount line-powered (90–263 Vac) module (NPB-PWR-UN),
or an external wall mount AC adapter (WPM-
XXX
).
The T-600 controller does not include an on/off switch. To apply power, you either:
•
if
, plug in its 2-position power connector.
•
if
, energize the AC circuit (90–263 Vac) wired to that module.
•
if
, plug in the power connector to the T-600.
Caution
Do not connect
both
the WPM-
XXX
and NPB-PWR / NPB-PWR-UN supplies at the same time, or
equipment damage may result.
1. A fourth power option is available: a T-IO-34 accessory module, which is a combination of the
module and two
T-IO-16 modules (plus two extra relays). Please refer to its mounting and wiring instructions document for more details.
