7. After the actuator(s) and all components are securely bolted

in place, attach the load to the actuator(s).

8. Install external stops and travel limiters as required.

Installation of these items is the customer's responsibility.

CAUTION: If limit switches are furnished by Enerpac,
they are NOT factory set. Limit switches should be set
by carefully moving the set position by hand or jogging

the motor. Exercise care when operating the unit at the
extreme limits of travel.

CAUTION: Emergency stop nuts are intended for use
only as secondary stops, in the event of overtravel
emergencies. Gear damage may result when emergency

stop nuts are used as the primary travel limit and other means of
overload protection are not incorporated into the system.

CAUTION: If operating at the upper limits of the
actuator rating, do not stop the load on the housing or
the hard external or internal stops. Failure to observe

this precaution may result in damage to the actuator's internal
gearing.

IMPORTANT: Positive stops or emergency stop nuts must
be positioned so that the stop contact for all units will occur
simultaneously to equally distribute the system stall load if
overtravel occurs.

9. Install shaft guards, coupling guards and other protective

devices as required, in accordance with all applicable safety
codes and regulations.
