The earth strap comes with a bolt (+ star washer) and tag on one end which is
attached to the hole situated below the power supply on the PCB (see Figure 7 for
position of ground hole).
The switches on the PSU PCB should be set as follows:

(See Figure 8 for diagrams of switch settings)
S1 - PC Address
This should be set to '1'. If a second rack is fitted in the Instation then the position
of the switch, on the PSU Board in the second rack, does not matter. If there is
more than one PC connected to the same Ethernet link, the switch should be set
to 2 for the PSU Board connected to the second PC, 3 for the PSU Board
associated with the third PC, etc. The switch setting should correspond to the last
digit of the TC12 PC SCN in the associated UTC System’s database.

S2 - Audio Alarm Configuration Switch
This is a 4-way DIL switch. The usual setting for this switch is as follows:
switch position 1 should be closed
switches 2, 3 and 4 should be open.
switches 2, 3 and 4 should be open.
The function of this switch is to enable certain inputs to the board, to cause the low
frequency alarm tone to sound.

The high frequency alarm tone is sounded if the Audio 2 Signal becomes active.
This is not configurable. It can only be disabled using the audio on/off switch (see
below).

Closing the appropriate switch causes the input signal indicated to cause a low
frequency alarm tone, should the signal become active. Note if more than one
switch is closed, any of the associated input signals becoming active, will cause
