Siemens servomotor:
GRA326, GNA326, GGA326.
Motorized fire dampers electical wiring
To connect the dampers to the power supply, proceed as follows:
• Check that the voltage and electrical frequency are equivalent to
those of the motor of the servomotor (check the motor's informa-
tion label);
• Make the connections as shown in the below diagram.
1 Negative (DC) or neutral (AC)
2 Positive (DC) or phase (AC)
3 Phase
4 Neutral

MAINTENANCE AND INSPEC TIONS
Fire dampers and control mechanisms do not require routine main-
tenance.
Extraordinary maintenance (repairs) and periodic inspection opera-
tions are the responsibility of the ventilation system operator.
