Connecting to Power
The GranDSLAM 4200 is powered by a nominal –48 or –60 VDC source
providing –40 to –72 VDC. Dual power feeds are provided for redundancy. The
terminal block accepts 18 to 14 AWG wire.
The 4200 GranDSLAM contains two external fuses, each with a visual spring
indicator and an alarm circuit indicator in case the fuse is blown.
Using a Single DC Power Source
Procedure
✔ Make sure that the DC power source wires are not powered (that is, the circuit
breakers or fuses are open at the source).
✔ The ends of the power source wires (18–14 AWG or 0.75–2.5 mm
2
solid or
stranded wire) must be stripped of insulation. If the wires are not stripped, strip
the tip of each wire about 1/2 inch (13 mm) before inserting the wire into the
appropriate terminal on the –48/–60V input terminal block.
To supply –48/60 VDC power to the GranDSLAM 4200 from a single power
source:
1. Insert the following wires into Terminal A and securely fasten each wire by
tightening the screw above it. The insulation should be fully within the terminal
block and no bare wire should be exposed outside of the block.
2. Clearly label these power source wires as –48V (or –60V) and RTN.
3. Turn on power to the GranDSLAM 4200.
4. Make sure the STATUS LED on the front panel is ON (green). See Chapter 3,
LEDs.
Insert the . . . Into the . . .
Negative wire from the power source –48/–60V A input terminal.
Positive wire from the power source Left RTN (return) terminal.
