Stampa la paginaThe 1.75" (4.45cm) high chassis fills a uniform one rack unit (RU) in height.
IMPORTANT NOTE:
There can be a tremendous amount of weight applied to the face plate when the unit
is fully cabled. Users are encouraged to provide a means of cable management at
the rear of the rack to avoid excessive cable weight force on the unit.
Because the device consumes very little power (<25 Watts) there are no venting
restrictions. This allows stacking devices without the need or provision for spacing in
between units.
4 Test Cable Wiring
Much like the internal circuitry, the R232's input and output connectors are a
precision component and must be treated as such. Therefore, it is critical that NO
EXCESSIVE FORCE BE APPLIED TO THE INPUT/OUTPUT CONNECTORS.
Do not exceed 10 in/lbs. (1.12 N/m) of torque on any F-connector!
OVER TORQUING THE CONNECTORS MAY CAUSE IRREPARABLE INTERNAL
Please be aware that generally available cable F-connector torque wrenches are
typically set for 20 in/lbs. used for outdoor connectors. Moreover, they are
notoriously unreliable in delivering proper torque for these precision components and
therefore it is strongly advised not to use them in this application.
4.1 F-Connection Rule of Thumb:
Finger tighten the cable to the F-connector, then tighten no more than a quarter (1/4)
turn if at all. This should provide a secure connection without applying a damaging
amount of torque to the connector.
