B. Install TT-NRM assembly
1. Attach the TT-NRM components to the DIN rail
The TT-NRM-BASE comes assembled. To remove a
module, pull up on the orange release tab until the mod-
ule releases from the DIN rail. Do not remove modules
while power is on.
To install additional TT-NRM-2RO relay modules, you
must first remove the End termination module (3)
and the adjacent DIN rail end stop. Slide the additional
relay modules into place and ensure they snap on to the
DIN rail. Replace the End termination module and DIN
rail end stop to the right of the last relay module added.
Refer to the TT-NRM Assembly diagram on page 2 for
the proper order of module assembly.
Important: Modules and/or external equipment may
be damaged if modules are not installed in the correct
sequence.
2. Attach the RS-485 network connection module to the
DIN rail.
Locate the module to the left side of the Network pro-
cessor. Press the module down onto the DIN rail to lock
it in place.
Connect the supplied ribbon cable between the Network
processor and the RS-485 connection module.
Use the screws provided to secure the ribbon cable con-
nectors.
3. Mount the power supply.
Mount the power supply on the DIN rail to the left of the
RS-485 network connection module.
