INSTALLING THE MMC SMART DRIVE
Figure 3-2: Recommended Signal Separation
To prevent excessive conducted emissions from a DC power source (typically 24V)
used for digital I/O, a .001 micro farad capacitor should be used. Connect the
capacitor from the +24V DC to COMMON at the distribution terminals.
WARNING: FEEDBACK DEVICE DAMAGE
Feedback Cable Installation and Removal
All power to the Smart Drive (24 Vdc and main AC power) must
be removed before connecting/disconnecting feedback cable
connectors at the Smart Drive (F1 and F2 connector) or at the
motor feedback device. Also, all connections must be secure
when power is applied. Failure to follow these precautions may
result in damage to the feedback device or Smart Drive.
