5. Installation
This device must be installed by qualified personnel. The installation consists of mounting the device,
connecting the antenna, connecting inputs and outputs, providing power, and configuring via a web
browser. This device must not be installed directly outdoors.
Attention! Before installing the SIM card in the card slot, please ensure that the PIN code is disabled.
5.1. Mounting
TCG120-4 should be mounted in a clean and dry location on a non-flammable surface. Ventilation is
recommended for installations where the ambient air temperature is expected to be high.
Mount the device to a wall by using two plastic dowels 8x60mm (example Wür th GmbH 0912 802
002) and two dowel screws 6x70mm (example Würth GmbH 0157 06 70). See Appendix C, fig. 1 for
mechanical details.
Maintain spacing from adjacent equipment. Allow 50 mm of space on all sides, as shown in fig.2 in
Appendix C, this provides ventilation and electrical isolation.
5.2. Connectors
Attention! Disconnect the power supply before wiring.
The correct wiring procedure is as follows:
•
Make sure power is turned off;
•
Make wiring connections to the terminals;
•
Apply power.
It is recommended to test and configure TCG120-4 without any controlled device.
Make sure that wires are properly attached to the terminals and that the terminals are tightened.
Not proper wiring and configuration can cause permanent damage to the module or the equipment
to which it is connected or both.
