Rack Dimensions (H x W x D):
• 2U rack mount chassis for use in standard EIA 19” rack.
3.26” x 19.125” x 8.5” (83mm x 486mm x 216mm)
Installation Instructions:
1. Mount unit in the 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. The unit is factory set for 24VAC operation.
For 28VAC operation, adjust unit prior to mounting and applying power as follows:
a. Open bottom of the unit by removing six (6) screws (Rack Mechanical Drawing and Dimensions, pg. 4).
b. Change the wire position so that the black wire [28V] is connected to the terminal marked [P] and
the yellow wire [24V] is connected to the terminal marked [S].
c. After securing all wires for proper voltage place bottom panel back on the unit and fasten with the six (6) screws.
Note: R2416ULCB set for 28VAC operation is not Class 2 Rated, not power-limited.
4. Plug power cord into a grounded 115VAC 50/60 Hz receptacle (Fig. 1c, pg. 3), ground should be connected
- 2 - R2416ULseries
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 avoiding potential damage.
All terminals with common suffix (P) “1P, 2P...” are the same polarity.
7. Set power disconnect circuit breaker to OFF position (Fig. 1d, pg. 3).
8. Connect devices to the removable terminal blocks marked [1P & 1N] through [16P & 16N] (Fig. 1a, pg. 3).
When wiring is completed on the terminal blocks they can be locked down by tightening screw flanges.
9. Upon completion of the wiring, set power disconnect circuit breaker to RESET (ON) position (Fig. 1d, pg. 3).
10. 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 (R2416UL, R2416300UL, and R2416600UL) - Set power disconnect circuit breaker on the back
of the unit to the OFF position (Fig. 1e, pg. 3).
Remove front faceplate to access fuses. Replace with fuses rated @ 3.5A/250VA (Altronix model # Fuse1).
b. Tripped PTC (R2416ULCB, R2416300ULCB, and R2416600ULCB) - To reset PTC, set power switch on the back
of the unit to the OFF position. After approximately 30 secs. set power disconnect circuit breaker to
the ON (RESET) position (Fig. 1d, pg. 3).
11. 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 unit’s electrical load ratings as indicated in reference chart (pg. 2).
Do not place mechanical load on the 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.
For fuse protected models:

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 product’s 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
no user serviceable parts inside. Refer servicing to qualified service personnel.
