THE DELTAMAX™ SYSTEM
INSTALLATION (continued)
When deciding how to best ground the controller in
a particular system, note that the controller's input
and output XLR-type connectors have pin 1 refer-
enced to chassis ground through a 20 k resistor
and a .01bF capacitor. This minimizes the possibil-
ity of a ground loop. Circuit ground ties to the chas-
sis ground internally at one point. The input to the
controller is active differential and the output is
transformer isolated.
Ventilation
Adequate ventilation should be proved in the rack
to maintain a reasonable operating temperature.
The ambient temperature inside the rack cabinet
should not exceed 60°C (140°F) under any condi-
tions.
Security
A security cover and attachment screws are sup-
plied to protect the control settings against uninvit-
ed adjustments.
Maintenance
Use a soft damp cloth to clean the unit. No other
maintenance is required.
