Mounting and Installation
Mounting location
•
In a cabinet on a flat surface
•
In a cabinet on a top-hat rail
•
In a panel (cabinet door) with the optional panel mounting kit
•
The following mounting locations should be avoided:
For the types with wireless transmission (-WEM or -WEB), avoid locations that interfere with the radio signals,
o
e.g. metal boxes or devices that generate electrical interferences.
Mounting instructions
See the TCI2 installation sheet, document no. 70-00-0688 or 70-00-0893 (www.vectorcontrols.com).
Selection of sensors and actuators
Temperature sensors
Use Vector Controls NTC sensors to achieve maximum accuracy: SDB-Tn10-20 (duct), SRA-Tn10 (room), SDB-Tn10-20 +
AMI-S10 as immersion sensor.
Actuators
Choose modulating actuators with an input signal type of 0-10 VDC or 4-20 mA (min. and max. signal limitations may be set
with parameters).
3-point actuators with constant running time are recommended.
Binary auxiliary devices (e.g. pumps, fans, on/off valves, humidifiers, etc.)
Do not directly connect devices that exceed specified limits in technical specifications – observe start up current on inductive
loads.
