Making Power Connections

Perform the following steps to apply power to the TSG-3800:
1. Ensure all fuses are removed.
For the TSG-3800 19-inch and TSG-3800 23-inch shelves, the fuses are located
above the POWER terminal block as shown in
A is controlled by fuses F1 and F3. Power B is controlled by fuses F2 and F4.
For the TSG-3800E 19-inch shelf, the fuses are located below the POWER
terminal block, as shown in
2. Locate the POWER terminal block and make the connections using 16 AWG
(minimum) stranded wire.
3. Connect primary power to the POWER A terminals and the secondary power to
the POWER B terminals. A #6 spade lug termination for each power lead is
recommended.
4. Measure the voltage at POWER A and POWER B (if used) and verify that it
measures from –38 to –72 volts DC (–48 vDC nominal). The inputs are protected
against reverse polarity.
5. Using a digital voltmeter, measure between ground and chassis and verify that
no voltage potential exists between them.
6. Insert the modules as described in
