DT9000 N
Mounting the instrument Four M3 threaded screws are needed for mounting the
instrument (these are not accessories). The type of the
screws depends on the wa -materia , whi e the dimensions
depend on the wa -thickness. The use of cross recessed
pan head screws is recommended to make the mounting
easier. The minimum screw- ength shou d be the wa -
thickness + 10 mm.
During mounting, p ease observe a safety ru es, and use
on y appropriate too s.
Secure the screws against getting oose. For this purpose
you may use spring ock or serrated ock washers.
Depending on the materia of the wa , and in order to
ensure the most practicab e mounting method, it is not
mandatory, of course, to use the above-described threaded
joints. Depending on the situation, specia screw types for
wood or for meta sheets can a so be used, or the joint can
be riveted too.
Mounting the front cover
back to its place
1. Check if there are a ien materia s eft in the housing, ike
sma too s, wire or meta pieces, p astic chips, etc. If there
are, remove them.
2. Put back the front cover of the apparatus, taking care that
the sea ing shou d get to its p ace. There shou d be no gap,
nor cab es caught between the housing and the front cover.
3. Tighten the front cover.

Select connection cable Take note the suitabi ity of the connecting cab e.
We recommend the use of screened twisted pair cab e. The
wire cross-section shou d be 0.25-1.5 mm2.
Select connection cable In particu ar, make sure that no potentia equa isation
currents f ow over the cab e screen. In case of grounding on
both sides (for suppress the inf uence of high frequency
interference signa s) this can be achived by use of a
capacitor (e.g. ceramic capacitor 1 nF, 1500 V) or separate
potentia equa isation. The ow frequency potentia
equa isation currents are thus supressed, but the protective
effect against high frequency interference signa s remains.
Inserting the cable into
the instrument
1. Prepare the cab e for the connection.
Remove approx. 30 mm of cab e mant e, strip approx.
8 mm insu ation.
2. Remove the instrument front cover (see chapter 4.3.).
3. Loosen compression nut of the cab e entry.
4. Insert the cab e into the instrument through the cab e
entry.

switched off.
The push-in direct connector assemb ies used a ow a fast
connection of the cab es.
Their proper usage is shown by the fo owing figure:
1. Push the stripped cab e-end unti it possib e into the
termina assemb y. In the case of f exib e cab e-ends, you
can faci itate opening the connection part by pushing down
the white button.
2. By pushing the wire in, the se f-c osing connection is
being estab ished. Check it by pu ing it outwards s ight y.
(3. When you disassemb e the cab e, push down the white
button by a screwdriver, and pu the cab e-end out.)
There is no need to use great force for pushing the cab e in,
neither for remova . The button can be pushed down easi y.
P ease do not exercise forces higher than necessary, as it
may cause damages to the termina assemb y.

Finishing step 1. Check if the cab es are connected proper y (have you
connected a the cab es; have you connected them to the
right p ace; is the connection stab e; do not the cab e-ends
touch each other).
2. Pu out the cab e s igh y trough the cab e entry to eave
on y the proper cab e- ength in the instrument inside.
3. Tighten the compession nut of the cab e entry, the sea
ring must comp ete y ancirc e the cab e.
Checking the
connections
After you have comp eted the connections, put the current
oop under vo tage, in such a way that the nomina 4-20 mA
current shou d f ow in the oop. If the connection is correct,
numbers or a characters has to appear on the disp ay.
If nothing appears on the disp ay, most probab y there is no
current f owing in the oop. Check if the current is present by
using an ampermeter. If the current va ue is in the
4-20 mA range, check if everything has been done in
accordance with Chapter 5.1 Connecting into the current
loop.
You may check the vo tage at the pins 5 and 6 of the
termina assemb y, the vo tage shou d be a va ue between
1.5 and 2.2 V, whi e pin 6 is the positive one, if the
connection is correct. In the case of reverse po arity, the
vo tage va ue is ess than 1 V, and 5 is the positive pin.
With this you have comp eted the connection of DT9000 N.
