DESCRIPTION
Please read these instructions and keep them in a safe place.
These instructions must be followed carefully to ensure
proper operation.
The nVent RAYCHEM TraceTek TTA-SIM must be installed in
an ordinary (non-hazardous) location. It may be used with any
TraceTek sensing cable, point sensor and/or normally open, dry
contact devices (float switch, pressure or vacuum switch, optical
probe with adapter, limit switch, etc.). Up to 150 m (500 ft) of
sensing cable can be monitored by the TTA-SIM. Contact factory
for information regarding longer monitoring distance.
An external disconnect device and appropriate branch circuit
protection (no more than 20 amp rating) should be provided for
the TTA-SIM. The disconnect device should be clearly marked
as such. Follow all national and local codes and regulations
applicable to the installation.
INSTALLATION ITEMS (NOT SUPPLIED)
• Wall fasteners for surface mounting (four screws)
• TT-RS485 telemetry cable (optional)
TOOLS REQUIRED
• Drill for making conduit / cable gland entries
• Phillips (cross-head) screwdriver
• Small flat-blade screwdriver
• Small needle nose pliers (required only for device
programming if digital communication is used)
• Tools to mount enclosure
STORAGE
Keep the TTA-SIM modules in a dry place prior to installation.
Avoid damage to components.
ADDITIONAL ITEMS
An agency-approved zener barrier must be used where sensing
cable connected to the TTA-SIM will be located in Class1 Div 1
(Zone 0 or 1 in Europe) Hazardous Locations.

Page 2: Selecting The Mounting Position
: In order to provide maximum electrostatic discharge Note protection, and to be CE compliant, the TTA-SIM must be grounded. Figure 3. Power connections 2 | nVent.com/RAYCHEM... - Page 3 The TTA-SIM can be used with any of the TraceTek family of Sensor connections (R G Y B) sensing cables including nVent RAYCHEM TT1000, TT3000, TT5000 and TT5001, as well as float switches and point probes. Connect the TraceTek leader cable to the lever operated sensor terminals on the relay unit as shown in Figure 4 and the following table.
