Installing the Monitor
The Series 4000 Precision Hygrometer monitor requires an operating environment of 0 to
40
°
C, 0 to 90 % RH.
The monitor case is designed for 19" 3U rack mounting. However, it can be used as a
bench mounted device without any special preparation.
For rack mounting, simply screw the monitor front panel to the front of the rack using
quantity 4 M6 x 15 mm screws and plastic inserts. The unit should be supported by
suitable horizontal runners. The front panel mounting alone is not sufficient to support the
weight of the entire unit.
NOTE:
A minimum depth behind the S4000 front panel of 511 mm is required for the
monitor, its connectors and wiring. Also, it is important that a sufficient flow of
ambient air reach the rear of the unit. The ventilation holes on the top of the
instrument must not be obstructed.
