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
°
°°
°
C.
Before operation the device should have a temperature of at least 10
°
°°
°
C.
•
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.
