Input Feed B and the Grounding Lug for the RPS AB6
Before you connect a power supply to the Remote Power Switch, test the voltage of your
power supply:
·
Connect the black common lead of a voltmeter to the ground terminal of the battery, and connect
the red lead of the voltmeter to the battery's –48 VDC terminal. The voltmeter should read
between –43 and –53 VDC . If the reading is outside this range, test the power supply.
To connect the RPS to a power supply:
Warning: Before connecting power feeds, make sure that the breaker for the power feed you're
connecting is switched off.
1. Use the grounding lug to connect the unit to earth ground. The grounding lug is next to the
symbol. Insert the eyelet of the earth ground cable between the two nuts on the grounding lug
(Ground cable not included). Tighten the grounding lug into place using your 7/16" nut driver.
2. Insert a battery ground into the lower terminal and tighten the nut down on the ground cable
using your 7/16" nut driver. If using the dual feed connector displayed in the example above,
tighten both nuts down on the connector.
3. Insert a –48 VDC line to the unit's upper terminal and tighten the nut down on the -48 VDC line.
If using the dual feed connector displayed in the example above, tighten both nuts down on the
connector.
4. Repeat Steps 2 and 3 for the remaining power inputs.
Note: You must connect A and B side power inputs to separate power supplies for your Remote
Power Switch to properly function
.
