NOTE:
Keep the packaging material for later use. The MG14 must be stored and transported in the
original packaging material only.
3 Examine the MG14 for completeness
4 Visually inspect the MG14 for signs of damage
DANGER
!
Damaged product.
Putting a damaged product into operation can be extremely dangerous.
Never attempt to put a damaged product into operation. Secure the damaged product
from unintended operation. Send a damage report to the haulage company or the
insurer.
3.2 Mechanical Installation
The MG14 can be used as follows: As a desk-top device, mounted in a control panel, or mounted in
a 19" rack. In each of these cases you must pay attention to the following safety note:
WARNING
!
Ambient temperature.
Exceeding the maximum permitted ambient temperature may damage the device.
Make sure that the maximum permitted ambient temperature is not exceeded and that
the air can flow freely through the louvers. Do not expose the device to direct sunlight.
3.2.1 Desk-Top Device
MG14 is delivered with four stuck gummy legs –no other protection is needed. The device can be
use as a desk-top like it is.

MG14 operating manual Rev 1.4
13
3.2.3 Rack Installation
The MG14 is designed for installation into a rack according to DIN 41 494 (19", 1 HU).
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 from foreign bodies and water) e.g. according to the EN 60204-1
regulations for switching cabinets.
Take appropriate measures to restore the required protection class of the rack.
In order to use MG14 in the rack there is necessary to remove four stuck gummy legs. For this purpose
proceed as follows:
1. Switch off the MG14 and disconnect it from mains power
2. Turn the MG14 upside down as shown in Fig. 3-1,
3. Remove ( unstuck ) the four stuck gummy legs
4. Turn the MG14 back to normal orientation and place it on the required location
Fig. 3-1 Unstuck gummy legs from the device
NOTE:
In order to reduce the strain on the front panel it is recommended to equip the rack chassis
adapter with a guide rail.
1. Insert the MG14 into the rack chassis adapter
2. Fasten the MG14 with the supplied collar screws and plastic sleeves to the rack chassis adapter

DANGER
!
Mains power.
Improperly grounded devices can be extremely dangerous in the event of a fault.
Use three-wire mains or extension cables with protective ground only.
Plug the mains cable into wall sockets with protective ground only.
1. Connect the European appliance connector of the mains cord with the mains connection of the
device
2. Connect the plug of the mains cable with the wall socket
NOTE:
If the device is installed in a switching cabinet, the mains power can be supplied via a
switchable central power distributor.
3.3.3 Ground
The ground screw (Fig. 3-4, item B) can be used to connect the MG14 with the protective ground of
the pumping station.
If required: Connect the protective ground of the pumping station with the ground screw. Use a
protective conductor.
The metal flanges of the B-A gauge sensors are connected to the ground via the measuring lines
inside of the MG14.
