Protection against electric shock
The system consisting of the control card (MCHSML****), other optional cards (MCHSMLSERO, MCHSMLEY0,
MCHSML4200, MCHRTF***0, CONVONOFF0 and CONV0/10A0, etc.) represent a control device to be incorporated into
class I or class II equipments. The class concerning the protection against the electric shock depends on how the control
device is being integrated into the unit realised by the manufacturer. The output digital contacts (relay) are of the micro
switch type.
Turn off the power before working on the card during mounting, maintenance and replacement.
The protection against the short-circuits, owing to faulty wiring, must be guaranteed by the manufacturer of the equipment
into which the control device is being integrated.
