If the remote sense leads are not attached the unit will automatically revert to internal sensing. The
internal sense point is at the output terminals of the cabinet. The sense leads should be twisted to
-
gether prior to minimize noise pickup.
Control & alarm wires should be bundled and routed through the clips provided.
Secure the control, sense and alarm cables in the cable clips. Insert each wire into the appropriate
terminal on the termination block and tighten. See Figure #10 or Figure #11 . The control and
alarm connections may exit either side of the cabinet.
The AC Fail, Minor Alarm, and Module Fail 1-4 terminals are connected to relay contacts on the
interface board. The relay contacts can be individually set to be normally open (NO) or normally
closed by configuring jumpers P21 through P26. The jumpers are located directly beneath terminal
block TB5 on the RSM 48/50 & 24/100 and beside terminal block TB3 on the RSM 48/30 & 24/50.
Refer to Table #2 or Table #3 for the required settings. Please note that the Module Fail relays
are normally 'energized' and the Minor Alarm & AC Fail relays are normally 'de-energized' when the
unit is powered up. This means that the contact states will be complementary to the 'normal' states
when the unit is not powered up.
The Remote Common terminal on the interface board is connected to the hot bus at the factory.
Thus if any of the four Remote Shut Down lines are connected to the ground bus (such as the
chassis) then the corresponding module will be shut down. This connection to the hot bus should
be removed if an external remote common is desired to activate remote functions. Assure that the
wire is completely removed.
The Remote Equalize should be connected between cabinets. When Remote Equalize is con-
nected to the ground bus, it will put all units into Equalize mode.
The +Sense and -Sense lines, if used, should be connected to the desired regulating point - most
likely at the battery terminals or charge bars. If multiple cabinets are used, the sense lines should
be connected from EACH cabinet to the sense point.
The +Forced Parallel and -Forced Parallel lines on the RSM 48/50 & 24/100 are used when multi
-
ple cabinets are present and and forced paralleling is desired and should be connected in parallel
between the cabinets. The RSM 48/30 & 24/50 have a single CURRENT SHARE line which works
the same way.
4.5.2 D.C. Output Connections
D.C. output wire must be UL approved File # B64801, XHHW or RHH/RHW (Canadian users;
RW90 Type). Control and sense wires must be UL approved Style 1015 (Canadian users; TEW
type). For ease of cable manipulation, the output cover plate can be removed until the end of this
sequence. Feed the cable assembly through the notch in the cabinet.
The output terminals are 3/8" studs with nuts and washers on 1" centers.
Crimp on the appropriate lugs to the two output cables. Secure the output cables to the output post
of the same polarity. Install the washers and nuts on top of the lugs in the same order in which
they were shipped from the factory. Refer to Figure #12 .
WARNING: Ensure that the polarity of the output of the cabinet and
the sense lines (if used) are correct. Verify polarity using a hand held
voltmeter. :WARNING
