3.1 INTRODUCTION
This chapter contains necessary information for the preliminary checks
and installation of the PJRL250.
3.2 UNPACKING
Unpack the amplifier and, before any other operation, check that the
amplifier isn’t damaged and that all controls on the front and rear panel are
in good condition.
3.3 INSTALLATION
1) Check that the line voltage selector is correctly set for the local
supply.
If not, remove the cover on which the voltages are printed and rotate
it until the required value corresponds to the arrow, and reinsert
it.
Check also that the fuse (6 Fig.1) mounted inside the cover is
present and in order.
The current capacity of the fuse are as follows:
220-240V - 4.0A
110-120V - 6.3A
For this equipments it's necessary to use delayed fuses.
2) Place the Mains power switch in the off position (4 Fig.1).
3) See SETUP 1 (Fig.4), connect a dummy load with 300W power rating
at 50 Ohm to the RF output (5 Fig.2) with a through wattmeter
(BIRD 43 or similar).
4) Switch on the mains switch and check the proper led is on.
5) Internal parameters control.
Select with the Meter Selector (8 Fig.1) the internal supply voltage
"V" and check the value of 50Vdc.
Select the current "I" and check that the value is between 0 and
400mA.
