GASKET

1. Make the panel cutout using the mounting

template dimensions in this chapter. Insert the

case assembly into the panel cutout.

2. While pressing the case assembly firmly

against the panel, slide the mounting collar

over the back of the controller.

If the installation does not require a NEMA 4X

seal, slide the mounting collar up to the back of

the panel tight enough to eliminate the spacing

between the gasket and the panel.

Slide the mounting col-

lar over the back of the

controller.

Place the blade of a

screwdriver in the

notch of the mount-

ing collar assembly.

3. For a NEMA 4X seal, place the blade of a

screwdriver in the notch of the mounting collar

assembly and push toward the panel while

applying pressure to the face of the controller.

Don't be afraid to apply enough pressure to

properly install the controller.

The seal system is compressed more by mat-

ing the mounting collar tighter to the front

panel (see picture). If you can move the case

assembly back and forth in the cutout, you do

not have a proper seal. The tabs on each side

of the mounting collar have teeth that latch into

the ridges on the sides of the controller. Each

tooth is staggered at a different depth from the

front so that only one of the tabs, on each side,

is locked onto the ridges at a time.

Removing the Mounted Controller from Its Case

1. From the controller's face, pull out the tab on

each side until you hear it click.

Pull out the tab on

each side until you

hear it click.

Grab the unit above

and below the face

and pull forward.

2. Once the sides are released, grab the unit

above and below the face with two hands and

pull the unit out. If it is difficult to pull the unit

out, remove the connectors from the back of

the controller. This should make it easier to

remove.

Ó Warning:

All electrical power to the controller and con-

trolled circuits must be disconnected before

removing the controller from the front panel

or disconnecting other wiring. Failure to follow

these instructions may cause an electrical

shock and/or sparks that could cause an explo-

sion in class 1, div. 2 hazardous locations.

Returning the Controller to its Case

1. Ensure that the orientation of the controller is

correct and slide it back into the housing.

2. Using your thumbs push on either side of the

controller until both latches click.

Note:

The controller is keyed so if it feels that it will

not slide back in do not force it. Check the ori-

entation again and reinsert after correcting.

Warning:

Use National Electric (NEC) or other country-

specific standard wiring and safety practices

when wiring and connecting this controller to

a power source and to electrical sensors or

peripheral devices. Failure to do so may result in

damage to equipment and property, and/or injury

or loss of life.

Note:

Maximum wire size termination and torque rating:

• 0.0507 to 3.30 mm

(30 to 12 AWG) single-

wire termination or two 1.31 mm

(16 AWG)

• 0.8 Nm (7.0 lb.-in.) torque

Note:

Adjacent terminals may be labeled differently,

depending on the model number.

Note:

To prevent damage to the controller, do not con-

nect wires to unused terminals.

Note:

Maintain electrical isolation between analog input

1 and switched dc/open collector outputs.
