Electrical Installation
AtmosAir 500 series systems require an average of 50 watts
per unit. A replaceable T 500mA, slow-blow 5mm x 20mm
fuse protects the unit.
Follow proper electrical procedures, guidelines, and codes
for providing power supplies to the systems,
including
requirements for conduit, sufficient ampacity, phase
balancing, etc. Electrical installation should be performed by a
qualified electrician.
1.
Field-install a junction box within 2.44 meters (8’) of the
unit(s). Each 500 series unit is typically shipped with a 10-
foot power lead in a flexible metallic conduit with a quick-
connect power plug on one end and bare wires on the other.
!!!WARNING!!!
The secondary voltage to the ionization tubes can be as high as 3000 volts AC. Do NOT connect to power before the installation is complete and all
personnel are aware of imminent operation. Always disconnect power to the unit before handling any of the components.
2.
The unit is equipped with a normally open relay that closes
on ionization start-up and opens on loss of power. This relay
can initiate a local alarm or be tied into a building automation
system. Connection is via a DB-9 connector. Pins 1 and 5,
starting from the top left, are the active pins. There is no
electrical power across the terminals.
