DURAG D-TB 100 Series Operating Manual

Operating Manual Terminal Box (D-TB 100, D-TB 200)

Safety Information

 T he installation, commissioning, operation, maintenance and dismantling of all de-
vices must only be carried out by qualifi ed specialised personnel and electrical work
only by qualifi ed electricians.
 P lease ensure that you have read and understood the operating manual, and store it
in a place where it can be referred to in future!
 I f necessary, load and unload the packages with an appropriate lifting device.
 T he applicable laws, standards or guidelines relating to the use or intended purpose
must be observed.
D evices must only be used in accordance with their proper and designated use. The

safety of operating personnel and the system cannot be guaranteed if the product is
used in a diff erent way from its designated use.
 Before commissioning the device it must be ensured that:
e lectrical work has been carried out properly and in accordance with local regula-

tions!
p rotection from electric shock is ensured!

a ll cables are suffi ciently dimensioned and secured!

 When working on an opened device, there is a:
DANGER
Risk to life due to electric current!
Improper handing will result in serious personal injury.
Once the housing or touch guard of the terminal box have been
opened, live parts are accessible.
Disconnect mains cables!
 Please also observe the operating manuals of the measuring devices to be connected.

Designated use

The terminal boxes are suitable for supplying DURAG measuring devices with the
required operating voltage. The type D-TB 200 also supplies the measuring devices with
the required purge air. In both types, mains and data cables for the measuring system
are connected to the available terminals in accordance with the relevant connection
diagram.

Installation

EN
 W hen choosing the installation location and during the installation of the terminal
box, the parameters specifi ed in the technical data must be complied with.
 T he intake air must be as dry as possible as well as free from dust and oil (please ob-
serve specifi cations on relative humidity).
 T he terminal box is installed with the cable glands facing downwards. Unused open-
ings must be sealed to prevent the penetration of moisture.
 T he terminal box must be freely accessible, e. g. for changing the air fi lter.

Planning instructions for electrical connections

 R oute cables for the mains and data cables separately.
T he mains cable should use H 07 RR – U 3 G 1.5 or the equivalent. The material of the

conductors and sheath must be appropriate to the conditions at the operating site.
 S ecure the mains cable using a 16 A circuit breaker. Install the circuit breaker next to
the terminal box and clearly mark it as the isolation switch for the device.
T he individual wires of the mains cable must be secured, e. g. using cable ties. When a

wire is released, it must not make contact with the adjacent terminals.
 C onnect the data cable to the terminals in the terminal box: with shielded lines,
twisted pairs of fi ne-wire fl exible cores, operational capacitance approx. 80 nF/km.
U se the appropriate twisted pairs of cores (e. g. RS 485 A and B, 4 ... 20 mA + and –) for

the associated connections!
 A lways connect the shielding on both ends.

Data cable connection

11
 S trip back approx. 20 mm of the outer insulating layer of the data cable above the shield-
ing in addition to the exposed cores.
Guide the data cable through the cable gland (4) and into the terminal box.

 Secure the cable and connect the shielding:
D -TB x00 Ax2-xxxxx-xx (see Fig. 1):
P ut the cable in position, place the shield terminal (3a) over the stripped shielding on

the guide rail (12) and engage it. Now move it to the desired position.
D-TB 200 Ax2-xxxxx-xx Fix the cable in place using the knurled screw (11). (Note: To remove the terminal, the

knurled screw is screwed completely upwards).
D-TB 100 Ax1-P5xxx-xx (see Fig. 2):

I f necessary, move the shield terminal (3b). To do this, loosen the hexagon socket

screw (14), set the terminal on the desired tapped hole (15), align it and tighten the
screw (14).
Using a screwdriver or other suitable tool, press the recess (13) down and slide the

stripped shielding between the clamping jaws. Now remove the screwdriver.
C onnect the wires in accordance with the connection diagram.

 F or D-TB 100 Ax1-P5xxx-xx, correctly align the housing cover before installation.
 A measuring head is connected via the factory-installed ca-
ble on the terminal box (TB – Fig. to the right) with M23
socket.
 F or measuring devices with two measuring heads (e. g.
D-FL 220) a terminal box with an additional panel jack is
7 3 4 5 6 7
used. An additional connecting cable with M23 plug and
socket to the cable ends is also required for measuring head
B. Measuring head A is connected via the factory-installed
cable on the terminal box with M23 socket. For measuring
head B, the socket of the connecting cable is inserted into
the M23 plug at the measuring head, the cable plug is then
inserted into the additional panel jack of the terminal box
(TB – Fig. to the right).
