3.2 Principle of operation
The overvoltage arresters B63-48, B63-32 are completely enclosed in
a stainless steel housing. They can be used for VEGA sensors of the
plics® family.
• Type B63-48 for 4 … 20 mA and 4 … 20 mA/HART sensors
• Type B63-32 for Probus PA and Foundation Fieldbus sensors
B63-48, B63-32 overvoltage arresters reduce any voltage surges that
may reach the signal cables to a harmless level. The devices contain
voltage-limiting components as well as gas conductors for bleeding
o impulses of up to 10 kA to ground.

3.3 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.
The packaging of standard instruments consists of environment-
friendly, recyclable cardboard. For special versions, PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out in due consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or con-
cealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
• Not in the open
• Dry and dust free
• Not exposed to corrosive media
• Protected against solar radiation
• Avoiding mechanical shock and vibration
• Storage and transport temperature see chapter "Supplement -
Technical data - Ambient conditions"
• Relative humidity 20 … 85 %
With instrument weights of more than 18 kg (39.68 lbs) suitable and
approved equipment must be used for lifting and carrying.

B63-48, B63-32 • For 4 … 20 mA/HART, Probus PA and Foundation Fieldbus circuits
33012-EN-190904
4 Mounting instructions
B63-48, B63-32 overvoltage arresters are screwed into the position
of the cable gland on the sensor housing. The thread of the overvolt-
age arrester must match with the thread on the sensor housing. The
cable gland of the sensor is screwed into the overvoltage arrester. No
further assembling necessary.
Note:
The attached O-ring seal must be used to reach the housing protec-
tion rating of the sensor with version M20 x 1.5.
Note:
In order to reach the housing protection rating of the sensor, PTFE
gasket strip must be used with the ½ NPT version. First of all, screw in
by hand; if necessary, use grease and nally tighten with a ½ turn with
a SW 27 wrench.2).
2) Do not use any grease for sensors with plastic housing

5 Connecting to power supply
5.1 Preparing the connection
Always keep in mind the following safety instructions:
• Connect only in the complete absence of line voltage
Danger:
The stainless steel housing of B63-48, B63-32 has no electrical
function and therefore provides no internal or external connection to
ground or potential equalization.
The plant operator is responsible for ensuring an adequate connec-
tion, for example within the context of protective grounding, depend-
ing on the installation and protection rating.
The B63-48, B63-32 exhibit a voltage resistance of 0.5 kV for one
minute in the signal circuit with respect to the stainless steel housing,
but not with respect to the green/yellow cable in the sensor circuit.
This must be taken into account for the electrical installation.
Before starting setup make sure that the power supply corresponds to
the specications on the type label.
5.2 Connection procedure
Proceed as follows:
1. Unscrew housing cover of the sensor
2. If a display and adjustment module is present, remove it accord-
ing to the operating instructions of the sensor
3. Unscrew the cable gland
4. Push the connection cables through the cable gland into the sen-
sor
5. Screw B63-48, B63-32 into the opening of the cable gland ac-
cording to the description under "Mounting instructions"
6. Shorten the connection cables of B63-48, B63-32 to the suitable
length, strip o the wire ends approx. 1 cm (0.4 in)
Note:
To ensure an eective overvoltage protection, the connection cables
should be as short as possible. Unnecessary cable should not be
wound up and placed inside the sensor housing. This could inuence
the protective function of B63-48, B63-32.
7. Connect wire ends red and black according to chapter "Wiring
plan" and operating instructions of the respective sensor
8. Connect wire end green/yellow to the internal ground terminal in
the sensor housing, connect external ground terminal to potential
equalisation
9. Pull out terminal block inside B63-48, B63-32 with pliers
10. Push signal cables and screen through the cable gland and con-
nect according to chapter "Wiring plan" to the terminals

11. Check all cable connections, especially the ground connection, to
make sure they are tightened suciently
12. Insert terminal block into its position by using the pliers. A me-
chanical coding ensures the correct position
13. Screw cable gland into the thread of B63-48, B63-32, tighten
compression nut. The seal ring must completely encircle the
cable

6.1 Maintenance
If the device is used properly, no special maintenance is required in
normal operation.
6.2 Rectify faults
The operator of the system is responsible for taking suitable meas-
ures to rectify faults.
The rst measure to be taken is to check the input/output signal as
well as the power supply. In many cases, the causes can be deter-
mined and faults can be quickly rectied.
On-site repair of B63-48, B63-32 is not possible.
Should these measures not be successful, please call in urgent cases
the VEGA service hotline under the phone no. [phone].
The hotline is manned 7 days a week round-the-clock. Since we oer
this service worldwide, the support is only available in the English
language. The service is free, only standard call charges are incurred.
Depending on the reason for the fault and the measures taken, the
steps described in chapter "Set up" may have to be carried out again.
6.3 How to proceed if a repair is necessary
You can nd an instrument return form as well as detailed informa-
tion about the procedure in the download area of our homepage:
www.vega.com.
By doing this you help us carry out the repair quickly and without hav-
ing to call back for needed information.
If a repair is necessary, please proceed as follows:
• Print and ll out one form per instrument
• Clean the instrument and pack it damage-proof
