American Fibertek PSR-1S - Manual (Page 5)

Up to fourteen plug in cards can be powered by the PSR-1.
LINE VOLTAGE
The input line voltage should be a nominal 115 VAC or 230 VAC, 47 - 63 Hz power
source, properly grounded and conforming to all local codes. A universal power
connector is provided on the rear of the unit to facilitate connection to the power mains.
INSTALLATION
This installation should be made by a qualified service person. All wiring methods should
be in accordance with the National Electric Code, ANSI/NFPA 70. Before inserting the
PSR-1 the line voltage selector switch must be set to the proper line setting. A small
screwdriver may be used. The unit slides in and is locked into place by four ¼ turn
fasteners. The line cord is then plugged in from the rear. Be sure that the power switch is
in the off (O) position before connecting the power source.
OPTIONS
Optional features include redundant supplies with automatic take-over. An SR-20R is
required for this feature. Also two supplies (master and slave) are required. The Master
supply powers the system as the Slave monitors the power bus. In the event of an over
voltage or under voltage condition, the Slave supply will disconnect the Master from
the bus.
CONTROLS AND INDICATORS
Front panel LEDs indicate positive (+DC) and negative (-DC) voltages and the AC line
(AC) being present.
Also available on the front panel, is the line fuse. A 5 X 20 millimeter fast blow type
should be used. There is a spare fuse behind the front handle. It is accessible by
removing the supply and sliding the plate to either side. Insert the handle cover back to
the original position and replace the unit. Qualified personnel should only attempt fuse
replacement.
CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE
ONLY WITH THE SAME TYPE FUSE. For 115VAC operation a 1A fuse is required. For
230VAC operation a 0.5A fuse rating is required.
