Power Input and Power Cord Rating
The 458-3SLB input voltage is rated for 85 to 240 VAC-RMS, 47 to 63 Hz. Before connecting
power verify that the
Power Entry switch is set to off
and that the Power Cord to be connected
to the 458-3SLB Power Entry is properly rated for the input voltage applied before connecting or
setting power on.
The cold start of the 458-3SLB is 20A at 110VAC-RMS and 40A at 220VAC-RMS. The 458-3SLB
Power Entry contains a 3-
Ampere Slow Blow fuse that is rated at 250VAC and is 0.250”Dia x
1.250” Long (6.35mm x 31.75mm). For replacement of the fuse use Littlefuse 0313003.HXP or an
equivalent rated fuse. Do not use smaller or larger current rated fuses and verify that the fuse is a
Slow-Blow type.
Enclosure Grounding
When installed in a Rack verify that the Rack is grounded and that the bolts holding the enclosure
to the Rack are tightened in order to properly Earth Ground the enclosure.
When not installed in a Rack connect an AWG-18 gauge (0.823mm
2
) wire between the lug at the
rear of the 458-3SLB and a good facility Earth Ground to ensure personnel Safety. Failure to
connect the enclosure to Earth Ground compromises Safety conditions and may also affect
system performance by exposing the system to various signals that are in the vicinity.
Disassembly
The top cover of the system may not be removed as it exposes personnel to hazardous power
line voltages. In addition, it voids the Telebyte warranty.
Equipment Safety
Do not remove or insert Line Modules with the 458-3SLB Power in the ON state. Set the Power
Entry switch at the rear of the system to the OFF state prior to Module removal and set it to the
ON state after removal or after the Module is replaced.
