3.5 Hot Sample Guard Assembly
The hot sample safety guard is supplied as a kit comprising the guard, the handles and fixing
screws and a warning label and fixing screws. See Fig - 2.2.4 to Fig - 2.2.6. to assemble the
handles and the warning label to the guard.
3.6 Electrical Connections
Connection by a qualified electrician is recommended.
Model ABA 7/35B is designed for connection to a range of power
supplies with the minimum of circuit modifications. It is initially supplied to
suit the voltage for which it was ordered; or for 240V 1-phase for a
‘multivoltage’ order.
Look at the rating label before connection to check the supply voltage and
frequency for which the unit is configured. If there is a difference between the actual supply and
the rating label, reconnect the wires between the terminal bock and the EMC filters according to
the appropriate diagram below.
If there is a need to connect the ABA to a voltage other than that shown on the label
when it is delivered, then it is essential to first ensure that wiring configuration shown in
table 3.6:1
is configured correctly for the intended new mains supply.
The supply should be fused at the next standard size equal to or higher than the rated
amperage. A table of fuse ratings (Table 26.2:1) is given in section 26.
Either wire directly to an isolator or fit with a line plug. An isolating switch should operate on
both conductors (single phase) or on all live conductors (three phase); it should be within reach
