QUICK INSTALLATION GUIDE
A.
Read all cautionary warnings in Section 1.
B.
Remove the charger from the packaging and inspect for damage. See Section 5.1 for information on
moving and lifting the charger. Notify SENS immediately
(1-800-742-2326)
if damage from shipping is
evident.
C.
See Section 5.2 for mounting options.
D.
All models except 400VAC and 480VAC include a 3-way AC input voltage selection jumper. Ensure the
AC voltage selection jumpers are in the correct position for your AC supply as shown below:
E. Connect
AC
wires—
Ensure that the AC input supply is de-energized and the charger AC input circuit
breaker is opened
. Wire the AC input circuit to the empty lugs of the AC input breaker. Connect the
earthed conductor of the AC input circuit to the grounding lug inside the charger. See
TABLE 2
for AC
input breaker wire size. See
FIG 1
,
FIG 2
and
DIA\00568
(back of manual) for wiring and breaker
location.
F. Connect
DC
wires—
Ensure that any battery disconnect device in the system, if used, is opened
(batteries disconnected from DC bus), and that the
DC output breaker in the charger is opened
. Connect
the DC output wires to the load side of the DC output breaker,
observing the correct polarity
as labeled
on the charger next to the output breaker. Make sure small signal leads also attached to the breaker remain
connected. See
TABLE 3
for DC output breaker wire sizes. See
FIG 1
,
FIG 2
and
DIA\00568
(back of
manual) for wiring and breaker location.
G.
Connect optional alarm wires
—
Alarm wiring enters the charger on the upper left side of the enclosure.
Knock out the conduit opening and connect alarm wiring, taking care to route the wiring through
appropriate cable guides provided within the charger. See
FIG 1
,
FIG 2
,
FIG 3
and
DIA\00568
(back of
manual)
for alarm wiring. See
TABLE 4
for alarm wiring connection locations.
H.
Energize the AC input supply at supply panel
—
With the charger input AC and output DC breakers still
opened
, energize the AC input supply, and check the voltage at the line (left) side of the input AC breaker,
making sure it is the correct value for the charger.
