2 Description
The PSU is available in two separate versions defined in
Specification on page 5.
The unit is housed in a metal case fitted with mounting lugs.
Cable gland entries are provided at opposite ends of the case
for supply voltage input and output cables respectively.
A printed circuit board assembly (see Figure 1) contains the
circuit components. The supply voltage input is connected to
terminal block (TB1) located on the pcb, adjacent to the fuses
F2 and F3. The constant current output terminal block (TB2) is
located on the gland assembly at the opposite end of the
assembly. The auxiliary 10 V output terminal block (AUX 10V) is
located on the PCB near to TB1. The pcb is mounted on a steel
chassis and secured by six screws. The cover is perforated to
allow ventilation for cooling.
IMPORTANT (NOTE)
The PSU has NO serviceable parts.
Two identical fuses (L & N) are mounted within the unit on the
mains input. A third fuse is connected in the DC line circuit of
the transformer. A fourth fuse is connected in the auxiliary
10 V DC line. The L & N fuses are a high breaking capacity type
and must be replaced only with identical types. See
Specification on page 5 for rating.

4 Mechanical installation
The PSU must be mounted in a clean, dry, well ventilated
position (on a wall or panel) in a safe area by means of the four
fixing lugs. Figure 2 gives dimensions and fixing details for the
unit.
Before commencing installation, ensure that the unit supplied
is suitable for the supply voltage available – see Specification
on page 5 and Figure 3.

Interconnection diagrams and cable
requirements
See Figure 4 for interconnections for typical gas analysis
systems.
Katharometer connections
Cable connecting the constant current DC supply from the PSU
to the katharometer should be selected so that the maximum
length between the katharometer and its associated PSU.
Note that the cable gland accepts a cable between 5 and 9 mm
in diameter.
Temperature control circuit
The cable connecting the auxiliary 10 V DC supply to the
katharometer temperature control circuit must have cable
conductance capable of passing 1 amp without undue voltage
drop or excessive heating.
Note also that the cable gland will accept a cable between 5 and
9 mm in diameter.

…5 Electrical installation
Accessing the PSU terminals
WARNING. HAZARDOUS VOLTAGES
If the PSU is cubicle mounted or has its cover removed
for test purposes, AC mains supply voltage is exposed
at certain locations within the assembly when
supplies are connected. Thus, there is a risk of
electrocution.
All normal precautions must be taken to avoid the risk
of accidental electrical shock during installation and
maintenance of the equipment. Ensure that the
supply cable is disconnected at its source before
touching any electrical connections.
CAUTION – PROPERTY DAMAGE
Ensure that the correct version of the unit has been
supplied for the supply voltage available. A 115 V unit
cannot be used with a 230 V supply or vice versa.
Check that the current output meets the
katharometer input requirements (see katharometer
data label) – see Figure 7. If in doubt contact ABB
Limited.
Remove the power supply unit cover to obtain access to the
separate labeled terminal blocks – see Figure 5.
To gain access, remove the four
screws and lift off the cover
Figure 5 PSU cover removal
Electrical connections
The mains terminal block, TB1, is situated next to the
transformer, T1, and fuses, F2 and F3.
Connect the AC mains input cable as in Figure 6.
IMPORTANT (NOTE)
Earth bonding to be made via M5 earth stud.

6 Servicing
Fuse replacement
There are no serviceable components in the PSU; the only
servicing that can be performed is fuse replacement – see
Figure 8. The fuses must be replaced only with those stated in
the specification. If a fault occurs, return the PSU to the nearest
ABB Service Centre or to the factory for repair.
