All conductors must terminate in a permanent way. Make sure all terminations are easily visible and available for maintenance purposes.

Tag ground connections with a clear message such as “CRITICAL CONNECTION: DO NOT REMOVE OR DISCONNECT”.

CAUTION

For an installed Option 11C Mini, the impedance of the link between the ground post of the Main Chassis and the single point ground to which it connects must be less than 0.25 Ohms.

CAUTION

Transients in supply conductors and ground systems can damage integrated circuits. This damage can result in unreliable Option 11C Mini operation. Damage caused by transients is not always immediately apparent. Degradation can occur over a period of time.
