Alpha Technologies APB HFC Voltage Booster - Manual (Page 17)

17 016-559-B0-001 Rev. A
2.0 Installation, continued
2.7 Power Up and Test
2.7.1 Initial Power Up
Tools Required:
• True RMS Volt Meter
• Clamp-On Amp Meter
Procedure:
1. Plug the Output Connector from the RF Module
into the J4 Output Connector (item 1) of the PCB.
2. Plug the Input Connector from the RF Module into
the J5 Input Connector (item 2) of the PCB. Verify
the GREEN LED (item 3) on PCB is lit.
4. Place a Clamp-on amp meter over the output wire
coming from the Output connector J4 on the PCB
and the RF Module. The current must be less than
8A RMS. If the current exceeds 8A RMS, resolve
the cause of the short-circuit or overload condition.
3. Using the volt meter, measure the output voltage
between TP13 and the enclosure chassis. The
voltage should be approximately 87Vac for the
87Vac confi guration or 63Vac for the 63Vac
confi guration.
There will be up to 90Vac present on the PCB when a live connector is plugged into the
input or output connectors.
