3.1 Personnel
3.2 Installation, Setup
Skilled personnel
The unit may only be installed by persons
who have suitable technical training and the
necessary experience.
The VGC401 is suited for incorporation into a 19" rack or
a control panel or for use as desk-top unit.
3.2.1 Rack Installation
DANGER
DANGER: damaged product
Putting a damaged product into operation can
be extremely hazardous.
In case of visible damages, make sure the
product is not put into operation.
The VGC401 is designed for installation into a 19" rack
chassis adapter according to DIN 41 494. For this purpose, 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. the EN 60204-1 regulations for switching
cabinets.
Take appropriate measures for the rack to
meet the specifications of the protection
class.
tinb01e1-f (2011-07) VGC401.om 13
Guide rail
In order to reduce the mechanical strain on the front
panel of the VGC401, preferably equip the rack chassis
adapter with a guide rail.
Slide rails
For safe and easy installation of heavy rack chassis
adapters, preferably equip the rack frame with slide rails.

3.2.2 Installation in a
Control Panel
DANGER
DANGER: protection class of the control
panel
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 control
panel to meet the specifications of the protection class.
For mounting the VGC401 into a control panel, the following cut-out is required:

tinb01e1-f (2011-07) VGC401.om
3.2.3 Use as Desk-Top
Unit
The VGC401 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.
n Stick the two supplied rubber feet to the rear part
of the bottom plate …
… and slip the supplied rubber bar onto the bottom
edge of the front panel.
Select a location where the admissible maxi-
mum ambient temperature (
→ 9) is not ex-
ceeded (e.g. due to sun irradiation).
tinb01e1-f (2011-07) VGC401.om 19
3.3 Mains Power
Connector
DANGER
DANGER: line voltage
Incorrectly grounded products can be ex-
tremely hazardous in the event of a fault.
Use only a 3-conductor power cable
(3×1.5 mm
2
) with protective ground. The
power connector may only be plugged into a
socket with a protective ground. The protecttion must not be nullified by an extension
cable without protective ground.
The unit is supplied with a 2.5 m power cord. If the mains
cable is not compatible with your system, use your own,
suitable cable with protective ground.
The socket must be fuseprotected with
10 A
max
Disconnecting device
acc. to EN 61010-1
If the unit is installed in a switch cabinet, the mains voltage should be supplied and turned on via a central
power distributor.

tinb01e1-f (2011-07) VGC401.om
Grounding
On the rear of the unit, there is a screw which can be
used to connect the unit to ground, e.g. using the
grounding of the pumping station.
Do not unfasten this
Ground screw

ground protection)
tinb01e1-f (2011-07) VGC401.om 21
3.4 SENSOR
Connector
The VGC401 is equipped with two different gauge connectors.
Caution
Caution: one channel measurement unit
Connecting more than one gauge at the
same time may lead to gauge destruction.

at once
only
Make sure that there is never more than one
gauge connected to the VGC401 at the same
time.
Connect the gauge to one of the two SENSOR connectors on the rear of the unit. Use a screened 1:1 cable
(electromagnetic compatibility). Make sure the gauge is
compatible (
→ 9).
DANGER
DANGER: protective low voltage
According to EN 61010, voltages exceeding
30 VAC or 60 VDC are hazardous.
Only connect a protective low voltage (SELV).

4.2 Turning the
VGC401 On and Off
Turning the VGC401 on
Turning the VGC401 off
Make sure the VGC401 is correctly installed and the
specifications in the Technical Data are met.
The power switch is on the
rear of the unit.
Turn the VGC401 on with
the power switch (or centrally, via a switched power
distributor, if the unit is incorporated in a rack).
After power on, the VGC401 …
• automatically performs a self-test
• identifies the connected gauge
• activates the parameters that were in effect before the
last power off
• switches to the Measurement mode
• adapts the parameters if required (if another gauge
was previously connected).
Turn the VGC401 off with the power switch (or centrally,
via a switched power distributor, if the unit is incorporated in a rack).
Wait at least 10 s before turning the VGC401 on
again in order for it to correctly initialize itself.
