2.4 Installation and Setup
The FLM-1 units are delivered completely assembled. The units are designed
for desktop installation or mounting in a 19-inch rack. Installation
procedures for the FLM-1 unit are provided in the following paragraphs. For
rack installation of FLM-1, refer to the Rack Mounting Kit for 19-inch Racks
guide that comes with the RM kit.
To complete the installation of FLM-1, you must perform the following (in
the given order):
• Determine the required configuration of FLM-1, according to your
application, and set the internal jumpers accordingly.
• Connect the subchannel and main link interfaces.
• Connect power to the unit.
Setting the
Internal Jumpers
Before connecting the interfaces and power to the unit, determine the
required configuration of FLM-1 and position the straps accordingly. To do
this, proceed as follows:
Warning
Access to the inside of the equipment is permitted only to authorized
and qualified service personnel.
To avoid accidental electric shock, always disconnect the power cord
before removing the unit from its casing.
1. Unscrew the upper cover screw located at the back of the unit.
2. Slide the rear drawer out.
3. Locate the strap marked “SELECT 6 OR 12 CHANNELS” on the circuit
board. For up to 6 channels with no control applications, place the strap
to 6. For any other application, place the strap to 12 (see Figure 2-1).
4. Locate the strap marked GND. According to your requirements, set the
signal ground to be connected to shielding (chassis) ground or floating
(NC). The factory setting is GND connected to Chassis ground. This
setting is strongly recommended unless it is absolutely necessary to do
otherwise.
5. Slide the rear drawer back to its place.
6. Fasten the upper cover screw at the back of the unit.
Caution
The safety status of the 4W port is TNV-1, operating within the limits of
SELV. If the 4W network does not fulfill this requirement, the signal ground
must be connected to the chassis ground.
