Overview of installation procedures for TT-NRM
1. Select a location for installation.
The TT-NRM may be installed in any panel or enclosure
suitable for electronic control devices.
The TT-NRM assembly is powered with line voltage and
switches relay contacts that may be connected to line volt-
age. Select an electrical panel or enclosure considering the
area classification (i.e., non-hazardous or hazardous), the
location (indoors or outdoors, exposure to moisture and/or
dust), and the chemical environment.
If ambient temperatures below freezing are expected,
install the TT-NRM unit in a heated location or use an
enclosure heater. If moisture is expected, install a drain in
the enclosure.
2. Size and install DIN rail.
Use the supplied DIN 35 rail. The rail may be shortened
if necessary. The width of the TT-NRM assembly is deter-
mined based on the number of TT-NRM-2RO relay modules
used.
A. Mount TT-NRM assembly in enclosure selected for the application.
B. Connect power and relay contact wiring.
C. Connect RS-485 cables and set address.
D. Update the TTDM-128 network.
