• Once the modification is complete, install the lid ensuring all the screws are
Note that if the user fits a lower value of internal resistor to allow higher transient
dissipation, then the user's software must ensure adequate thermal protection for the
resistor. Failure to do so can cause the resistor to rupture. Consult the manufacturers
data sheet carefully.
1.6.3.3
The reverse voltage protection MOSFET dissipates an appreciable amount of power.
If the user is satisfied that this is not required, they can easily remove it by using the
following procedure. Alternatively, the user can use the auxiliary DC input on the 7-pin
output connector but this also bypasses the DC input current transducer and its
associated trip protection.
• Follow the procedure given in Section 1.6.2 “Accessing The System” for

1.6.3.4
All the non-isolated feedback signals are brought to a series of links that run along the
edge of the isolation barrier. In order to access these signals, the user should rigidly
carry out the procedure given below. Failure to do so could represent a safety hazard
to the user.
• Follow the procedure given in Section 1.6.2 “Accessing The System” for
• Disconnect the input wiring from the DC supply outlet.
• Ensure that the earth (ground) continuity is maintained to the unit.
• In order to make the links for the non-isolated signals, it is recommended that two

accessing the unit.
0.3" pitch, 14-pin DIL resistor packages are used. These should be of the
"straight-through" type with 7 independent resistors. The suggested value is
330Ω, as this will provide some ESD protection without too high a source
impedance being introduced. Note that LK28 has no circuit connections and is
provided to allow the second DIL resistor package to be installed. If the user
decides to fit links or individual resistors, these should be installed so that not
more than 4 mm of lead protrudes beneath the PCB.

connected to the enclosure chassis and is therefore also referenced to ground.
