• All conductors must be terminated in a permanent way. Make sure all
terminations are easily visible and available for maintenance purposes.
• Tag ground connections clearly with a message such as "CRITICAL
CONNECTION: DO NOT REMOVE OR DISCONNECT".

When the Option 11C Mini is installed, the impedance of the link
between the ground post of the Main Chassis and the single point
ground to which it is connected must be less than 0.25 Ohms.
Reliable Option 11C Mini operation depends on high-precision
internal circuitry, which can be damaged by transients in its supply
conductors and ground system. Damage to sensitive devices, due to
transients, is not always immediately apparent: degradation can occur
over longer periods of time.
