Installation

ATTENTION:

Do not connect this equipment with

power applied. Failure to follow this directive may
result in fire or serious injury.

ATTENTION:

Starting and stopping with the start/stop

terminals does not disconnect AC power in the stop
position. A hardwired AC power disconnection switch
must be mounted between the AC source and terminals
L I and L2. This is required, as the DC3 drive does not
have an armature loop contactor. A single fault like a
power device short may cause motor rotation when in
the stop mode. The user is responsible for assuring safe
conditions for operating personnel by providing suitable
guards, audio or visual alarms, or other devices. Failure
to observe these precautions could result in bodily
injury.

ATTENTION:

To provide the motor with overload

protection, local, national, and international codes
(e.g.,NEC/CEC) require that a motor thermostat,
internal to the motor, be installed or an electronic
thermal motor overload relay, sized to protect the
motor, be installed between the motor and the drives
output terminals.
