ATTENTION: Only qualified personnel familiar with DC

drives and associated machinery should plan or implement the

installation, start-up and subsequent maintenance of the system.

Failure to comply may result in personal injury and/or equipment

damage.

ATTENTION: To avoid an electric shock hazard, ensure that

all power to the drive has been removed before performing the

following.

ATTENTION: This drive contains ESD (Electrostatic

Discharge) sensitive parts and assemblies. Static control

precautions are required when installing, testing, servicing or

repairing this assembly. Component damage may result if ESD

control procedures are not followed. If you are not familiar with

static control procedures, reference A-B publication 8000-4.5.2,

“Guarding Against Electrostatic Damage” or any other

applicable ESD protection handbook.
