Internal Components
The Auxiliary Load Module (ALM) is designed for multiple applications and
allows for simple installation. Components provided are listed below.
Relays
There are three single-pole, double-throw relays, rated at 10 amps/250 VAC
(8 amps/30 VDC–for resistive loads), with gold contacts providing “dry contact”
closures to increase the low-end signal range.
• Relay RY9 and RY10 are used for battery voltage related functions.
• Relay RY11 can be connected to an external indicator device to display or
sound an alarm whenever the inverter AC output is lost.
• The common, normally open , and normally closed contacts are available on
each relay.
Relay Connections
• Common (COM) - The COM contact switches between the N.C. and N.O.
terminals depending on whether the relay is energized or not (de-energized).
• Normally Closed (N.C.) - The N.C. contact is connected to the COM terminal
of the relay when the relay is de-energized.
• Normally Open (N.O.) - The N.O. contact is connected to the COM terminal
of the relay when the relay is energized.
CAUTION: These relays are not intended to directly
control a load or charging source. Rather they are used
to send a signal or operate the coil of another, higher
amperage device which does the actual switching of
power. A 6.3-amp fuse is included to help protect each
of the relays. Connection to a high amperage device
will open the fuse in the common line and possibly
damage the relay. Damage to these relays from
overloading is not covered by warranty and requires the
ALM to be returned to a repair center.
Relay Terminal Block
Connections to the ALM are accomplished by the nine position, spring-clamp,
terminal block with quick connect levers. All relay contacts (N.O., COM, and N.C.)
are available at this connector, which accepts wire sizes from #28 AWG to #14 AWG.
No tools are required to secure the wires as the spring clamp holds the wires
securely in place.
