Caution:
The rectifier must be mounted on a vertical surface so that it stands vertically, and is not
laid flat on its side. Observe orientation arrow printed on front panel.
Do not mount rectifiers above each other.

Cabling
It is important that all cables (except AC) are less than 10 feet in length. The rectifier is not designed for cables
greater than 10 feet or for connection to outside cables.
Parallel/Redundant Wiring Configuration
AC:
The length of the AC cable to the SPS is not critical. The unit only draws 300W and they will accept a wide
range of input voltages. The AC cable to the rectifier should have a disconnect switch at its supply, so the unit
can be isolated for installation or servicing. It is recommended that an un-switched permanent outlet be used,
so the rectifier will not be accidentally unplugged from the supply. When hard wiring AC input, the IEC AC cord
provided should be wired as follows:
BLK
WHT
GRN

Load and Battery:
It is important that the lengths of these cables are kept to a minimum to reduce voltage drop. A
fuse MUST be installed between the battery and the SPS, to protect the unit, load and battery. The fuse should be
mounted close to the battery, and have a high rupture current capability just above the unit’s capability. This fuse
protects the wiring and the SPS from over current.
Note:
For 48 volt positive ground (-48V) systems, install this fuse
on the negative (-) side.

* For 48 volt systems, install
battery fuse on negative (-)
lead.
** For long cable runs to
battery, use both sets of battery
output fast on terminals and
parallel cables at battery.
