3 Installation
Skilled personnel
The unit may only be installed by persons
who have suitable technical training and the
necessary experience or who have been
instructed by the end-user of the product.
The TPG 261 is suited for incorporation into a 19" rack
or a control panel or for use as desk-top unit.
DANGER
Putting a product which presents a visible
damage into operation can be extremely
hazardous. If the product presents a visible
damage do not put it into operation and make
sure it is not inadvertently put into operation.
The TPG 261 is designed for installation into a 19" rack
chassis adapter according to DIN 41 494. For this pur-
pose, four collar screws and plastic sleeves are supplied
with it.
DANGER
DANGER: protection class of the rack
If the product is installed in a rack, it is likely
to lower the protection class of the rack
(protection against foreign bodies and water)
e.g. according to the EN 60204-1 regulations
for switching cabinets.
Take appropriate measures for the rack to
meet the specifications of the protection
class.

In order to reduce the mechanical strain on the front
panel of the TPG 261, preferably equip the rack chassis
adapter with a guide rail.
For safe and easy installation of heavy rack chassis
adapters, preferably equip the rack frame with slide rails.

DANGER
DANGER: protection class of the rack
If the product is installed in a control panel, it
is likely to lower the protection class of the
control panel (protection against foreign
bodies and water) e.g. according to the
EN 60204-1 regulations for switching cabi-
nets.
Take appropriate measures for the control
panel to meet the specifications of the pro-
tection class.
For mounting the TPG 261 into a control panel, the fol-
lowing cut-out is required:
M3 or ø3.5

55.9
The admissible maxi-
mum ambient tem-
perature (→9) must
not be exceeded nei-
ther the air circulation
obstructed.
For reducing the mechanical strain on the front panel,
preferably support the unit.
3.2.2 Installation in a
Control Panel

18 BG 5195 BEN / A (2011-05) TPG261.oi
nSlide the TPG 261 into the cut-out of the control
panel …
… and secure it with four M3 or equivalent screws.
The TPG 261 is also suited for use as desk-top unit. For
this purpose, two self-adhesive rubber feet as well as a
slip-on rubber bar are supplied with it.
nStick the two supplied rubber feet to the rear part
of the bottom plate …
… and slip the supplied rubber bar onto the bot-
tom edge of the front panel.
3.2.3 Use as Desk-Top
Unit

BG 5195 BEN / A (2011-05) TPG261.oi 19
Select a location where the admissible maxi-
mum ambient temperature (→9) is not ex-
ceeded (e.g. due to sun irradiation).
DANGER
DANGER: line voltage
Products that are not professionally
connected to ground can be extremely
hazardous in the event of a fault.
Connect the product according to the local
regulations and ground it correctly.
The unit is supplied with a power cord. If the mains con-
nector is not compatible with your system, use your own,
suitable cable with protective ground (3×1.5 mm3).
The socket must be
fuse - protected with
10 Amax
If the unit is installed in a switching cabinet, the mains
voltage should be supplied and turned on via a central
distributor.
3.3 Mains Power
Connector

20 BG 5195 BEN / A (2011-05) TPG261.oi
Do not unfasten
this screw
(internal ground
protection)
Connect the gauge to the sensor connector via
a sensor cable set available from us (→sales
literature) or your own, screened (electromag-
netic compatibility) sensor cable. Make sure the
gauge you are connecting is compatible
(→9).
