Custom Rack Design
1. A custom rack is required for mounting the SL4 Receiver for a
rack/chamber application.
2. Determine the number of SL4 receivers that are needed.
3. Determine the vertical spacing of the SL4 receivers. The
height and recommended spacing is shown in Figure A. This
spacing may vary depending on the ITA xture height that
will be used. It must be possible for the ITA xture to clear
the bottom of the SL4 directly above.
4. Determine the number of SL4 receivers that will be placed
side by side. The SL4 mounting bracket allows receivers to
overlap and share a common center mounting bar (Figure
B).
5. The rack should include 10-32 mounting holes for each
receiver. It is recommended that these holes be placed at
.765” intervals, vertically, to allow for future expansion.

KEYING PIN KIT, RECEIVER AND ITA
PART # 310 113 501
The SL4 keying kit includes two pins and screws which
provide six different keying options. The SL4 system is
designed to accept two kits which increase the keying
options to 36.
Figure A. In order to mate the SL4, the keying pins must be in opposite positions on the receiver and ITA.
INSTALLATION
1. Align the keying pin in the desired location. Place the keying pin in the hexagonal opening in the SL4 receiver (See Figure 1).
2. Secure the keying pin with the 4-40 screw.
3. Secure the other keying pin in the corresponding location in the SL4 ITA (Figure A).

Prior to engaging an ITA with the receiver for the rst time, ensure all modules (ITA and receiver) are properly installed. This involves
inspection of modules to ensure proper mounting and to verify module positioning. Module positions are shown in Figure A. Modules
must be installed such that Pin 1 of each respective mating receiver and ITA module pair are adjacent. VPC recommends that Pin 1
always be positioned to the left in the Receiver and ITA frames. All ITA modules must match the respective receiver modules. It is crucial
for all modules to be installed properly.
ENGAGEMENT
1. Ensure that the handle is in the full open position.
2. Place the ITA xture on the SL4 platform between the guides
and slide forward until the xture reaches a positive stop.
3. Close the handle to engage the system.
DISENGAGEMENT
1. Open the handle to disengage the system.
2. Slide the ITA xture away from the receiver and remove.
Improper installation will damage the
Modules, and possibly the ITA and/or Receiver.
ITA & RECEIVER ENGAGEMENT
In the event of complications, a trained technician
should be notied immediately to avoid any damage
to the system. This applies to any difculties that may
be experienced during engagement.

ITA Frame is not lined up when in the process of engagement with receiver
• This may indicate that the ITA was damaged and is out of alignment or that a Module is not mating with its intended module.
• Remove and inspect the ITA for alignment
• Check for foreign objects/tools.
• Inspect the matching of modules - power ITA module to mate with power receiver module, etc.
Excessive force is needed to engage the Handle
• This may indicate that the ITA was damaged and is out of alignment or that a Module is not mating with its intended module.
• Remove and inspect the ITA for alignment. Contact Virginia Panel Corporation – unauthorized user adjustments to System will void
the warranty.
• Check for foreign objects/tools.
• Contact damage may provide enough resistance to notice. Upon replacing a contact in the ITA, the mating contact on the
Receiver side should also be inspected and replaced if necessary.
• Verify the orientation of the receiver and ITA modules.
• Inspect the matching modules - power ITA module to mate with power receiver module, etc.
ITA will not engage with the receiver after diagnosing the above problems
• Contact Virginia Panel Corporation – unauthorized user adjustments to the system will void the warranty.
No continuity upon engagement
• When replacing an ITA contact, the mating contact on the receiver side should also be inspected and replaced if necessary.
• Check wiring and replace if necessary.
• Contact not secured in module.
• A contact may be damaged. Visually check all contacts for damage to potentially isolate damaged pin prior to checking for
continuity with a multi-meter.
A “short ” in the wiring upon engagement
• A damaged contact(s) may cause high resistance. Upon replacing a contact in the ITA, the mating contact on the Receiver side
should also be inspected and replaced if necessary.
• Check wiring and replace if necessary.
Receiver and ITA will not disengage
• This may indicate that the engagement mechanism within the receiver is faulty -contact Virginia Panel Corporation immediately-
user adjustments to system, unless authorized, will void the warranty.
TROUBLESHOOTING
Forceful engagement of the Receiver and the ITA
will result in serious damage to multiple parts of
the system (Modules, Receiver, ITA and Contacts)!

The following is a listing of precautionary notes found within this manual and otherwise. They should be noted and followed for the
equipment to operate at an optimum state.
• Never probe a contact without using a mating patchcord as a test lead.
• Never forcefully engage a system if there is an excessive amount of resistance on the handle.
• Never allow an ITA to drop as this may cause misaligned engagement and/or irreparable damage.
• Always insert and extract a contact insertion/extraction tool in line with the contact. Never apply pressure to the side as this may
break either contact or tool. This also applies to forming and enlarging tools.
• It is advisable that power to the interface system be disconnected prior to handling and maintenance.
• Caution should always be used when engaging, making sure that all foreign objects are removed from the system.
• The foremost precautionary step that needs to be taken is to protect the Interface System from damage caused by people
(bumping into the receiver/ITA assembly with a box, chair or electronic equipment for example). To prevent this, VPC recommends
engaging either the ITA or the receiver protective cover to the receiver when not in use.
