2.4 INSTALLATION PROCEDURE OUTLINE
WARNING:
The SAGEON PSMC I utilizes connections to battery for power and sensing
connections that must include inline protection (fuses or current-limiting resistors) to
eliminate potential hazards to personnel and equipment due to accidentally shorted
battery connections.
GENERAL PROCEDURE OUTLINE
2.4.1 Verify the part number on the SAGEON PSMC I conforms to the voltage of the power
plant before installation. The SAGEON PSMC I functions with +/-24 Vdc or +/-48 Vdc
input power without adjustment. Maximum voltage input is 60 Vdc; minimum is 20 Vdc.
2.4.2 Locate the unit as directed in the “Selecting a Location” section and mount with four
standard rack-mount screws; two of the screws must have “Paint-Cutting” washers
installed to assure proper grounding for ESD protection.
2.4.3 Locate power source and sense points for battery power, plant voltage and load voltage
connections. These connections must be fused at the source with inline protection or utilize a
sense and control panel connection. Ideally, both the battery and ground leads should be
protected. The minimum requirement is a fuse in the battery leg. A separate ground lead
should be run to one of the common
Plant Ground
(PLANT GND, TB2 pins 2-12 and 21-
24) screw terminals. This connection references the SAGEON PSMC I internal ground to the
power plant ground reducing noise levels and providing a convenient plant ground
connection point for ground closures on output relays.
2.4.4 A list of connections should be created for all the SAGEON PSMC I wiring before actual
wiring begins using the Datasheet in the back of this manual. The Datasheet will greatly
simplify the wiring process and provide a permanent record of the SAGEON PSMC I
wiring.
2.4.5 Locate each sense point for plant voltage and shunts to determine what type of inline
protection and cable routing is required. Note connection and protection requirements on
Datasheet.
2.4.6 Locate rectifier connections for
Equalize
,
Restart
,
HVSD
inputs, and
RFA
outputs to
determine connection requirements. The connections for
Equalize
,
Restart
, and
HVSD
MUST all be battery OR ground closures simultaneously e.g.
Equalize
CANNOT be a
battery closure while
HVSD
and
Restart
are ground closures. This information determines
the connection to the common “control return” (CTRL RTN) on the SAGEON PSMC I. The
RFA
inputs are ground closures.
Note:
Add this information and any lug requirements on the Datasheet. Determine best cable routing to
the rectifier connections. The
Equalize
,
Restart
, and
HVSD
connections can be “daisy chained”
as necessary. The SAGEON PSMC I accepts up to 16 individual
RFA
inputs.
2.4.7 Locate fuse alarm (
FA IN
) connection points. Five individual inputs are provided for
Charge
,
Discharge
,
Battery
,
Sense/Control
, and one
Spare
. Multiple discharge fuse
alarms can be “daisy chained” if desired.
