Rack Dimensions:
3.25”H x 19.125”W x 8.5”D
Installation Instructions:
1. Mount unit in desired rack location (Space unit at least 3” from any video monitors), Do not obstruct side air vents.
2. Set power disconnect circuit breaker to OFF position (Fig. 1D, pg. 3).
3 All units are factory set for 24VAC operation.
For 28VAC operation, adjust unit prior to mounting and applying power as follows:
Change the wire position so that the wire marked [28V] is connected to the terminal marked [P] and
the wire marked [24V] is connected to the terminal marked [S].
Note: R248ULCB set for 28VAC operation is not Class 2 Rated, not power limited.
4. Plug power cord into grounded 115VAC 50/60 Hz receptacle (Fig. 1C, pg. 3), ground should be connected
as indicated in (Fig. 1E, pg. 3).
5. Set power disconnect circuit breaker to RESET (ON) position (Fig. 1D, pg. 3).
6. Measure output voltage before connecting devices. This helps avoid potential damage.
All terminals with common suffix (P) “1P, 2P...” are the same polarity.
6. Set power disconnect circuit breaker to OFF position (Fig. 1D, pg. 3).
7. Connect devices to removable terminal blocks marked [1P & 1N through 8P & 8N] for eight (8) output models
(Fig. 1A, pg. 3).
When wiring is completed on terminal blocks they can be locked down by tightening screw flanges.
8. Upon completion of wiring, set power disconnect circuit breaker to RESET (ON) position (Fig. 1D, pg. 3).

9. Green power LEDs on faceplate will illuminate when power is present. When an output is in a trouble condition
(blown fuse or tripped PTC) the corresponding LED will not be illuminated (Fig. 1, pg. 3).
a. Blown fuse (R248UL) - Set power disconnect circuit breaker on back of unit to the OFF position (Fig. 1D, pg. 3).
Remove front faceplate to access fuses. Replace with fuses rated @ 3.5A/250VA (Altronix model # Fuse1).
b.Tripped PTC (R248ULCB) - To reset PTC, set power disconnect circuit breaker on back of unit to the
OFF position. After approximately 30 secs. set power disconnect circuit breaker to the ON (RESET) position
(Fig. 1D, pg. 3).
10. Illuminated power disconnect circuit breaker with manual reset:
OFF position - Switch not Illuminated. Outputs not powered.
RESET (ON) position - Circuit breaker illuminated. Outputs powered.
Circuit breaker tripped - Circuit breaker is not Illuminated. Power LEDs on faceplate are not illuminated.
Outputs not powered.
To reset circuit breaker set power disconnect circuit breaker to RESET (ON) position (Fig. 1D, pg. 3).
Note: Do not exceed units electrical load ratings as indicated in reference chart (pg. 2).
Do not place mechanical load on unit. Unit is designed optimally for normal data room office installations.
Data racks should always be properly ventilated.
WARNING: To reduce the risk of fire or electric shock, do not expose the unit to rain or moisture.
This installation should be made by qualified service personnel and should conform to all local codes
and in accordance with the National Electrical Code.

The lightning flash with arrow head symbol within an equilateral triangle is intended to alert the user to the
presence of an insulated “DANGEROUS VOLTAGE” within the products enclosure that may be of sufficient
magnitude to constitute an electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the literature accompanying the appliance.
CAUTION: To reduce the risk of electric shock do not open enclosure. There are
