1.5.2. Equipment Safety
To avoid damaging your product, please observe the following:
1.
Fuses: To avoid possibility of fire hazard, always replace fuses with the
same type and rating of fuse as recommended on the power supply rear
label.
2.
The input of the transmitter has an optional built-in bias for inserting DC
power up the coax to the LNB. Make certain any equipment or test
equipment connected to the transmitter input can withstand this bias.
3.
The output of the receiver is AC coupled and can withstand the bias from a
satellite receiver.
Do not exceed 25V DC bias.
4.
Do not allow any dirt or foreign material to get into the optical connector
bulkheads. This may cause damage to the polished optical connector end
faces.
5.
The optical fiber jumper cable bend radius is 3 cm. Smaller radii can cause
excessive optical loss and/or fiber breakage.
6.
If multiple transmitters are installed in the chassis allow sufficient room for
adequate ventilation; otherwise the units may overheat causing possible
safety hazard or equipment damage.
7.
When several units are installed on one 7000M chassis, ensure that the total
units’ current (including any LNB bias) does not exceed 2A per power
supply (e.g. if there are two power supplies the current should not exceed
4A.)
