account:
w Ensure that the supply voltage corresponds to the specifications on the type label.
w All covers required for contact protection must be fitted.
w If the controller is connected with other units in the same signal loop, check
that the equipment in the output circuit is not affected before switch-on. If
necessary, suitable protective measures must be taken.
w The unit may be operated only in installed condition.
w Before and during operation, the temperature restrictions specified for
controller operation must be met.
SHUT-DOWN
For taking the unit out of operation, disconnect it from all voltage sources and
protect it against accidental operation. If the controller is connected with other
equipment in the same signal loop, check that other equipment in the output cir-
cuit is not affected before switch-off. If necessary, suitable protective measures
must be taken.
