MTC64 Relay Board

Relay Expansion Board for MTC64 Main Board

Installation and User's Manual

Important Notes

•

Dangerous voltages may appear at the pc board, electronic parts and wires

during operation if the relays are used to switch voltages beyond 40V.

•

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

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

with all safety rules valid in the country where the MTC relay board is

installed.

•

Not qualified personell is not allowed to install and run the MTC relay board!

•

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

relay 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 !

•

If the relays are used to switch voltages beyond 40V the complete

construction has to be mounted into an isolating case. It has to be

impossible to touch any part that may lead any voltage beyond 40V

(including cables, electronic parts, connectors, pcb tracks, wires, cables

and so on).

•

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

forbidden if voltages beyond 40V are used!

•

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

•

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

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

completely from the power supply during any work at the boards.

•

For all connections and wiring connectors and cables have to be used that

are suitable and licenced for the voltage and current in question.

•

Because of heat emmission 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.

•

No liquids or conducting materials must get into the construction. If this

should happen the board must be disconnected from power immediately

and be examined, cleaned and eventually be repaired by a qualified person.

•

Never subject the construction to temperatures above +50

°°

C or below -10

°°

Before operation the device should have a temperature of at least 10

°°

•

Do not place the device into direct sun light. Do not install the instrument

near heat sources.

•

Never use the device in the immediate proximity of other electronic devices

(e.g. monitors, computers) since this could create disturbances within both

devices.

•

The terminal screws have to be tightened very fast to avoid slipping out of

the cables.
