Preparation for Mounting
Open the knockouts as required on the base unit. The holes are sized for the PG-9 threaded strain relief provided in the kit.

For Wall Mounting
Use the two holes in the
back plate to mount the
TTC-1 base unit to the
wall using suitable wall
fasteners. The mounting
holes are 4mm diameter,
separated by 85mm (center
to center). The mounting
screw holes are recessed
into a molded well that
is 7 mm in diameter. It is
recommended to use a J15
metric screw with a head
diameter small enough to
fit into the molded well.
For proper orientation, the
terminal strip must be on the left, as shown in Figure 2.

LEADER
Loosen the two captive screws at least 10 full turns. You may
hear a click when screw is fully released. Use a gentle rocking
motion to pull the module top away from the base.
Note: If the screws are not fully released the base can
be damaged during this step. The screws are captive
and will be retained with the module when separated from the
base.

For DIN 1 Rail Mounting
Attach the optional rail
mounting clip (TTC-DRC)
to the base unit and clip
base unit on rail. Remove
the top housing from the
TTC-1. Place one of the
hex nuts in the molded
hex cavity in the center
of the DIN rail plate. Align
the DIN rail plate with
the bottom of the TTC-1
base and insert one of
the screws through the
insulating collar and the hole in the center of the base. Turn the
screw to secure the base. Insert the second hex nut into the
remaining molded hex cavity at the end of the hex plate and use
the second screw to secure the plate.
