System 350
The Y350R is a rectified Class 2, 24 VAC power
supply module designed specific ally for use with
System 350™ Modular Control Systems.
As with all System 350 products, the Y350R is housed
in a compact NEMA 1, high-impact plastic enclosure.
The modular design provides eas y , plug-in
connections for quic k ins tallation and future
expandability.

IMPORTA NT: All Series Y350R Power Modules
are designed for use only in
conjunction with operat ing
controls. W her e an oper ating
control failure would res ult in
personal injury and/or loss of
property, it is the responsibility of
the installer to add dev ic es
(safety, lim it controls) t hat protect
against, or systems (alarm,

The Y350R operates f r om 240 V A C or 120 V A C
power. A 24 VAC, Clas s 2, step-down trans former
brings the voltage to a level which the Syst em 350
modules will accept. There are no adjustment s for the
power module.

nstallation and Wir ing
I
The Y350R case has provis ions for mounting to a
standard 35 mm DIN r ail, or can be mounted using t he
four key slot m ounting holes located in the rear of the
case.
Mount System 350 modules in any convenient location
using either the DIN r ail m ounts or the mounting holes
located on the back of the control case. The
components are not pos ition sensitive, but should be
mounted so they can be eas ily wir ed and adjus ted.

heckout Procedure
C
IMPORTA NT: All wiring must be inst alled to
conform to t he National Electrical
Code and local regulations.
1. Secure the module to the DIN rail, wall, or panel.
!
WARNING: Electrical S hock Hazard.
Disconnect power supply before
modules are interconnected and
wiring connections are made to
avoid possible electrical s hoc k or
damage to the equipment.
2. Connect input wiring to the Y350R power module.
Strip approximat ely 3/8 inch from the wir e
insulation, insert the wire under each terminal
screw, and tight en. (See Figure 3.)
Note: If conduit is used when installing Syst em 350
components, be sur e to connect the hub t o the
conduit before the hub is s ec ur ed to the
enclosure.
Before applying power, m ak e s ur e ins tallation and
wiring connections are acc or ding to job specifications .
After necess ar y adjus tments and electr ic al
connections have been made, put the syst em in
operation and observe at leas t three complete
operating cycles before leaving the installation.
roubleshooting
T
If the control syst em does not function properly and
the Y350R is suspect , proceed as follows:
1. Connect a Digital Voltmeter (DVM) between the
24V (+) and COM (-) terminals located on the
control module’s left-side connector. (Terminal
designations are marked on the control module.)
2. Select DC volts on the DVM and verify that the
voltage is between 16 and 38 VDC. If the DVM
reading is within range, t he Y 350R is functioning
properly.
Note: Consult the
appropriate control bulletin for a complete
system troubleshooting procedure.

3. If the DVM r eading is not within the indicated
voltage range, check wir ing and c or r ec t if
necessary. I f the wiring is correc t and the reading
remains out of range, replace the Y350R.
