Access Cover Removal (Fig. 9)
CAUTION
Equipment Damage Hazard.
Improper cover removal can damage electric 
connections.
Pull the cover along the axis of the actuator.
The cover contains contact sockets that must connect 
to actuator contact pins.
Bending these pins can permanently damage the 
device.
NOTE: This cover can be removed before or after actuator 
mounting.
In order to wire the device, the access cover must be removed 
as follows:
1. Remove the screw from the center of the cover, set the 
screw aside.
2. Pull the cover along the long axis of the actuator.
3. If the actuator is not yet mounted, set it aside.
4. Remove conduit dust covers as necessary.
5. Thread wire through conduit holes.
6. Connect wires as appropriate to the terminal block(s). 
(See Fig. 10 and 11.)
NOTE: With US Models, use 1/2 in. NPS strain relief 
gland or 1/2 in. conduit adapters. Recommend 
using flex conduit.
With European Models, use M16 strain relief 
gland.
