TTI PL154 - Installation

Installation
Mains Operating Voltage
Check that the operating voltage of the instrument shown on the rear panel is suitable for the
local supply. Should it be necessary to change the operating voltage range proceed as follows:
1. Ensure that the instrument is disconnected from the AC supply.
2. Remove the screws holding the case upper and handle.
3. Lift off the case upper.
4. If the transformer primary taps are marked: A 0-110-120 B 0-110-120, rewire as follows:
240V operation: Neutral (blue) wire to A0; Link (red) wire from A120 to B0;
Live (brown) wire to B120.
230V operation: Neutral (blue) wire to A0; Link (red) wire from A110 to B0;
Live (brown) wire to B120.
220V operation: Neutral (blue) wire to A0; Link (red) wire from A110 to B0;
Live (brown) wire to B110.
120V operation: Neutral (blue) wire to A0; Link (blue) wire from A0 to B0;
Link (brown) wire from A120 to B120; Live (brown) wire to B120.
110V operation: Neutral (blue) wire to A0; Link (blue) wire from A0 to B0;
Link (brown) wire from A110 to B110; Live (brown) wire to B110.
Alternatively, if the transformer primary taps are numbered 1 to 6, rewire as follows:
230V operation: Neutral (blue) wire to 6; Link (red) wire from 3 to 4;
Live (brown) wire to 1.
115V operation: Neutral (blue) wire to 6; Link (blue) wire from 3 to 5;
Link (red) wire from 2 to 4; Live (brown) wire to 1.
Note: Units factory set to 220, 230 or 240V will have no blue link wire - this must be provided
when converting to 110/115/120V operation. When converting a 110/115/120V unit to
220/230V/240V the blue link wire should be discarded.
5. Reassemble in the reverse order.
6. Change the fuse type if necessary.
Important Note: Safety regulations state that the AC line voltage to which the apparatus is set
must be clearly marked on the outside. If the line voltage setting is changed, it is imperative that
the voltage marked on the label close to the power lead entry point is also changed.
Fuse
The AC fuse is located on the back panel; note that the PL320QMT and PL330QMT have an
additional AC fuse for their logic output sections. The correct fuse type is 20mm x 5mm 250V
HBC time-lag with the following rating:
