Power Connector
The GranDSLAM 4200 is powered by a –48 VDC source providing –40.5 to
–57.0 VDC. Dual power feeds are provided (A and B) for redundancy. The terminal
block accepts 16 or 18 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.
CAUTION:
Make sure that the DC power source wires are not powered (that is, the
circuit breakers or fuses are open at the source).
Procedure
To supply –48 VDC power to the GranDSLAM 4200 from a single –48 VDC power
source:
1. Strip the tips of the power source wires (about 1/2 inch or 12.7 mm in length)
before inserting the wire into the 2-position plug.
2. Insert the wires into the supplied 2-position plug with screw flange and
securely fasten each wire by tightening the screw above it. The insulation
should be fully within the plug and no bare wire should be exposed outside of
the plug.
NOTE:
You should clearly label these power source wires as – 48V and RTN
respectively.
