Installation

Electrical Installation of the Wall Mount Electronics Version
Connect the TCM to the TCE (see chapter 3.2.1)
Open the safety screw at the display cover of the TCE with the provided Allen key.
Remove the display cover of the TCE by turning it counter clockwise.
Pull out the display.
Prepare the cable for installation:
Separate the single wires for about 4 ¾ inches (12 cm)
Strip the end and cover it with a cable end sleeve
Connect an about 2 ¾ inches (7 cm) long stranded wire to the shield
Feed the cable through the cable gland.
Connect the shield to the PE screw.
NOTE:
In bigger installations a separate PE connection with a high cross section (> 1.5 mm²) is recommended for
avoiding high equalizing currents in the shield.
Connect the individual conductors to the cage clamp terminals as required.
Push a small screwdriver into the upper (smaller) opening of the terminal, feed the cable into the bigger opening
and pull out the screwdriver.
For the right connections refer to chapter 2.3.
Adjust the position of the cable in the cable gland in that way that the single conductors remain short but free of
tension and fix the cable in the cable gland.
Put in the display again. The display can be positioned in four different orientations, separated by 90°.
Perform
– if necessary – a function test and make the necessary settings (see chapter 4.5).
Close the display cover.
Fasten the safety screw if necessary.

Power Supply and Grounding
3.2.3.1.
24 V DC Power Supply
The TCE requires a regulated DC power supply of 24 V ±20%.
The power supply input of the TCE is protected by a fuse. As a protection against fire in case of a short in the
supply cable, the output of the power supply must be equipped with a fuse with a rating not higher than the
current carrying capacity of the cable used.
For connecting the TCE use shielded cables. If several cables are used, each cable should be shielded
properly.
Connect the ground of your power supply to terminal 51 and the 24 V to terminal 50. (see Fig. 11)
