MTC64 Power Board

Mains Switches Expansion for MTC64 Main Board

Installation and User's Manual

Important Notes

•

DANGER TO LIFE !

•

Dangerous mains voltages (115V AC / 230V AC) appear at the pc board,

electronic parts and wires during operation.

•

Because of electrical safety installation, wiring and operation of the MTC

power board has to be carried out by qualified personnel only that is

familiar with all safety rules valid in the country where the MTC power board

is installed.

•

Not qualified personell is not allowed to install and run the MTC power

board !

•

If you are not sure if your knowledge is sufficient to install and run the MTC

power board do not install and operate the device.

•

The user has to read the installation manual carefully and follow all

instructions in the manual meticulously !

•

The complete construction has to be mounted into an isolating case before

the mains voltage is applied. It has to be impossible to touch any part that

may lead mains voltage (including cables, electronic parts, fuses, fuse

holders, connectors, pcb tracks, wires, cables and so on).

•

Operation of the MTC power board outside such a housing is strictly

forbidden!

•

In case that a metal housing is used it has to be connected to earth/shield.

The cross section for the earth/shield cable has to be more than for the

mains cables. In Germany only yellow/green cables are allowed for

earth/shield wiring. This color is not allowed to be used for any other

connection.

•

Connecting and wiring the boards has to be carried out without mains

voltage applied to the board. Therefore the board has to be disconnected

completely from mains during any work at the board (even for fuse

replacement !).

•

For all main connections and wiring (i.e. all connections to mains and to the

loads) connectors and cables have to be used that are suitable and licenced

for the voltage (115/230V AC) and current in question.

•

The single fuses (i.e. the fuses located at the MTC power board for each

output) are equipped with 1A from the factory and must not be replaced by

higher values or bridged (exception: if only 8 or less outputs are used the

value may be increased to 2A max.).

•

For the mains input a fuse (fast blow) has to be installed that is equal to the

sum of all loads that are driven (depends even upon the number of outputs

that are actually wired). The maximum allowed value for this fuse is 16A !

•

Because of the heat emmission of the sold state relays the complete

construction has to be cooled to avoid overheating. Possibly a housing with

ventilation slits or an additional fan has to be used.

•

The complete construction must never be operated outdoors but only in

dry, closed rooms. Never use it in a humid or wet environment nor near

inflammables.
