Installation and user reference guide
The 42-CIB2-24MO provides 24V DC power to operate two low voltage motors. The motors can be manually
operatedwith the switches on the lid, or operate automatically when driven by an Advancing Alternatives
Environmental Control or a third party ventilation controller.
Motor connections should be made with SJOOW wire and use the following sizing guidelines. Up to 100' use
14/2 awg; 100' to 200' use 12/2 awg.
There are 2sizes of circuit breakers included. Use the following guidelines to properly protect your motor. 60
-100 nm motors use 5A and 180 nm motors use 7.5A.
24 VDC motors only
Shock hazard. Always remove power before opening box.

Environmental Control Inputs
Your ventilation control must provide
"Dry Contacts". The 42-CIB2-24MO
when operated in "Auto" mode sends
out a 24V DC power Signal. Contact
your Control Manufacturer if you are not
sure. Connecting input and output wires
to anything other than a dry contact will
cause a fire hazard or serious damage
and will void the warranty.
If your Environmental controller does
not provide Dry Contacts we have an
add on module that can be connected
directly to the 42-CIB2-24MO that will
allow the use of powered contacts.
Please contact our Sales department,
877.546.2257 and request item
number 42-DRYCONTACT.

Connected motors may run in the
opposite direction as indicated by the
manual control switch. If this occurs
reverse the polarity of the motor by
reversing the wire positions connected
to that motor's terminal screws.

There are 4 circuit breakers in this box. They are designed to
give protection from overloads.
When a breaker trips (a tab pops out of the breaker) check
curtains for any electrical issues or mechanical obstructions.
Then press the tab back into the breaker to reset it.
Two of these breakers are on the circuit board. Each protects
one unit. If one breaker trips, the other unit will function.
Note: The breaker may not connect immediately after being
reset. The breaker needs to cool to resume operation
The two circuit breakers on the bottom of the box protect the
transformer. If either one trips, there will be no power to any
units.
