SECTION 4 : INSTALLATION
4.1.
GENERAL INSTALLATION
The THYROMAT is a complete bolt-on unit keeping the installation simple. The control unit is
encapsulated in a dust proof enclosure which is mounted to the thyristor stack. Similarly the thyristor
stack is a bolt on unit and is also secured to the equipment (differences in the mounting arrangement of
the thyristor stack depend on the model to be used). The electrical interface with the equipment is by
means of terminal lugs and/or connector blocks.
Certain THYROMAT variations have protective covers over thyristor stacks. The cover serves as a
protective screen to prevent damage to property and personal injury from accidental contact with the
exposed live components of thyristor stacks.

4.2.1.
General
The THYROMAT is a simple item to mount. THYROMAT is provided with the correct fasteners to secure the unit
on to the mounting surface. In the event that a repairable item is removed for repairs place the fasteners in
safekeeping for future use. When replacing repaired units use the original fasteners, wherever necessary replace
damaged or lost fasteners with physical equivalents.
4.2.2.
Mounting Instructions
Before mounting the THYROMAT, make sure that the mounting surface is of sufficient physical strength to carry
the weight of the complete unit. The following paragraphs list the mounting instructions for the THYROMAT,
refer to figure 4-1 for mounting details:-
Figure 4-1 : Mounting The THYROMAT - BD Crane Controller
1.
Mount the THYROMAT using the mounting holes provided by the thyristor stack. It is important to
note that the mounting screws also provide the unit with an additional earth return, make sure that the
unit’s mountings are clean and that a good earth is established.
