1.3.3 Repair Service
All warranty repairs are performed at no cost. Positron reserves the right to repair
or replace any equipment that has been found to be defective.
For information about out-of-warranty repairs, contact Positron’s Repair
Department. Due to the varied nature of repairs, no specific turnaround can be
guaranteed, but average turnaround time is 20 working days from date of receipt.
In emergency situations, special arrangements can be made. All repaired items
are warranted for a period of 90 days.
Before returning any items to Positron for repair, warranty repair or replacement,
call the Repair department to obtain a Return Material Authorization (RMA)
number. Parts returned without RMA numbers cannot be accepted. The RMA
number must always be clearly marked on all boxes, crates, and shipping
documents. Bulk repairs (more than five items) will require additional processing
time, so please take this into consideration when requesting an RMA number.
To accelerate the repair process, whenever possible, include a report detailing the
reason for return with the unit(s). Also, please include the name and phone
number of a person who can be contacted should our Repair department need
further information.
When packing items being returned for repair, please ensure they are properly
packed to avoid further damage. TeleLite plug-in cards should never be shipped
while installed in a shelf; this will cause damage that can extend the repair period.

Wall-Mount Power Supply Chassis model 750003
2.1 Introduction
The Wall-Mount Power Supply Chassis provides a means to use any of the
Teleline Power Supplies (751313MC, 751316, 751318MC, 751319MC, 751324)
or Battery Backup Module (751312) outside of the Teleline Shelves. The Chassis
mounts either flat on a wall or perpendicular to the wall to save space. Multiple
modules can be used to provide redundancy or backup. The Chassis has an
input/output terminal block and a battery backup terminal block to connect other
Chassis to it. The Chassis is equipped with spring-loaded locking mechanisms to
prevent cards from dislodging due to vibration.
The Wall-Mount Chassis allows the user to configure the output to floating
(24 Vdc/48 Vdc), negative voltage (-24 Vdc/-48 Vdc) or positive voltage
(+24 Vdc/+48 Vdc) through a jumper setting (W1) located on the backplane of the
Chassis.
QThe default setting is for -24 Vdc/-48 Vdc.
For a view of the Power Supply Chassis, see Figure 1 on page 15.
For a view of the jumper W1, refer to Figure 3 on page 19.

2.2 Description
Below is a description of the Chassis. For a view of the detailed section, please
refer to Figure 1 on page 15.
2.2.1 Input/Output terminal block
Input power is brought to the Chassis through the bottom three contacts of the
terminal block. Depending on the Power Supply being used, it can be fed either
120 Vac, 130 Vdc, 48 Vdc or 24 Vdc. Although the Power Supply Modules are not
polarity-sensitive, the power has to be wired according to the polarity indications
on the terminal blocks.
The output from the Power Supply comes out of the top three pins of the terminal
block. The top contact is the positive lead, the second contact provides the
negative lead of a 24 V power output and the third contact provides the negative
lead of a 48 V power output.
The fourth and fifth output pins provide alarm contacts. Whenever the output of a
Power Supply fails, the alarm contact on the unit will close, these alarm contacts
are provided through these two pins. When two Power Supplies are used with two
Power Supply Chassis, the alarm contacts of each of the Chassis can be wired in
parallel or separately to provide an alarm for the system or each Chassis. If one
unit fails, then an alarm is raised while the second unit still provides power to the
system.
For a view of the terminal block, refer to Figure 2 on page 17 and
Table 2 on page 18.

2.2.2 Power Supply/Battery Back-up terminal block
This terminal block provides charging power to a second Chassis used to house a
Battery Back-up Module 751312.
When a second Chassis is used to provide redundancy, its output will be
connected to this terminal block on the primary Chassis.
It is also possible to provide 48 V battery back-up using two 751312 units by
wiring the output accordingly. See section 3.5 on page 25 for more information.
For a view of the terminal block, refer to Figure 2 on page 17 and Table 2 on page
18.
2.2.3 Input fuse
The input fuse is connected in series with the Live lead of the input power feeding
the Chassis to provide overcurrent protection in case of damaging surges or
failure of the Power Supply Module. The fuse is a FAST, 5A/125V, 3AG type fuse
and must be replaced with the same type of fuse.
2.2.4 Ground lug
The Chassis must be grounded through the ground lug to a solid local ground
using a #10 AWG or bigger, wire.

2.2.5 Ground jumper setting
The backplane of the Wall-Mount Chassis is equipped with a jumper setting, W1,
that allows the output to be configured as floating, negative voltage or positive
voltage referenced to ground. The unit is set at the factory to provide negative
voltages (-24 Vdc/-48 Vdc) for Teleline/TeleLite installations.
The configurations are well indicated on the backplane at the different locations
where W1 can be installed.
QFor a view of the jumper W1, see Figure 3 on page 19.
