The actual connection procedure is straightforward. Simply connect the leads to the RFL
3000 unit, beginning with ground. Ensure that each lead is securely tightened.
Note: The GND should be hooked up first. The 4K unit has a floating ground, so the
user may elect to Ground or = terminal to suit the customer’s use.
Before connecting hot lines to the Terminal Block of –48VDC, 24VDC or 125VDC,
always use a digital voltmeter to measure the output voltage of the power supply and
determine the lead which is more “+ve potential”. The more “+ve” voltage lead from
48V or –48V supply must be connected to the post labeled “+”.
An ON-OFF manual switch is optional for DC power. This can be used to cut off
power connections and as a RESET for the 4K-Series Switch.
B4.1 UL Requirements
1.
For power and earthing wiring, use minimum 22 AWG size wiring.
2.
Fastening torque of the lugs on the terminal block: 9 inch pound max.
3.
Use only with listed 2A circuit breaker provided in the building installation.
4.
Equipment for use in a Restricted Access Location only.
5.
Centralized DC Power Source cable securement, use at least four cable ties to
secure the cable to the rack at least 4 inches apart with the first one located
within 6 inches of the terminal block.
B5.0 OPERATION
Operation of the RFL 3000 Ks with the optional -48VDC, 24VDC & 125VDC
power supply is identical to that of the standard AC-powered models.
B6.0 ORDERING
INFORMATION
To order the optional -48VDC power supply factory installed, add a suffix of “--
48VDC” after the product’s standard model #. Example:
RFL 3000 4K24-48VDC.
Similarly, to order the optional 24VDC or 125VDC industrial specific power
supply factory installed, add a suffix of “ 24VDC” or “125VDC” after the product ‘s
standard model #. Example:
RFL 3000 4K24- 24VDC
or
RFL 3000 4K24- 125VDC
.
