    Unused slots in the System 10/20 chassis are populated with blanking plates to prevent access to user I/O signals that may be present. Blanking panels are available to order from Pickering in a variety of slot widths. If the product is not used in this manner for example by using an extender card then additional care must be taken to avoid contact with exposed signals.

If remote mounting is Very High Voltage Switch Specification not chosen then the high voltage modules may be mounted in a “Combined” System 10/20 case, however this will result in a Max Standoff Voltage: 7500V DC (7500V ACpk) increase in switching noise within the system case.

    The module is designed for indoor use only. PRE-OPERATION CHECKS (UNPACKING) 1. Check the module for transport damage and report any damage immediately to Pickering Interfaces. Do not attempt to install the product if any damage is evident. 2. Position the chassis relative to any other equipment the module(s) will connect with. Ensure the chassis is not connected to the electrical supply.

    SECTION 5 - CONNECTOR INFORMATION pickering 20-310/320 Interlocking The 20-310/320 modules have the facility for an external interlock. This may be used to shutdown external high voltage sources if all connectors are not properly attached to the switching unit. Each high voltage connector has two pins dedicated to interlock (R & S), these pins are isolated from all other connections and are shorted together on the rear of the connector.
