Figure 4-2 : Electrical Mounting of The THYROMAT Controller
1.
Check that the integrity of the earth between the THYROMAT and mounting surface is good
(the measured resistance should be 0 ohms). In the event that the earth does not conform,
make sure that the THYROMAT mountings to the mounting surface are stripped clean of paint
and other contamination
and if necessary install an earth strap.
2.
Make sure that all the leads to the THYROMAT unit have a fair amount of slack so that they do
not assert unnecessary mechanical stresses to the electrical terminals.
2.&3. When connecting the electrical cables to the THYROMAT and thyristor stack (
&
), make
sure that the correct connector lug sizes are used (refer to Table 4-4
Connector Lug Data).
Where fasteners are used to connect the electrical lugs to the THYROMAT, make sure that
they are torqued down to the correct values (refer to Table 4-4
Connector Lug Data).
The THYROMAT must always have an earth connected to the earth terminal provided on the
controller’s terminal strip.
3.
Make sure that all the leads to the thyristor stack have a fair amount of slack so that they do
not assert unnecessary mechanical stresses to the electrical terminals.
