7 Transport and Storage

Transport and storage are only permitted in the original packing.

8 Receptacle Installation

8.1 Enclosure mounting

Securely mount the receptacle in a vertical position as illustrated, 

using three 5/16″(8 mm) screws and suitable washers. Mounting dimensions 

are marked on the back of the receptacle housing.

8.2 Conduit/Cable installation

For conduit installation, connect 1 1/2″NPT conduit to the hub and avoid misalignment.

For cable installation, connect a listed cable fitting to the hub. Conduit/cable fitting should

not be tightened more than 60 ft-lbs (81 Nm) of torque.

8.3 Auxiliary contact

When using the 6 A rated early break and late make auxiliary contact 

for an electrical interlock or other control signal, connect 12 AWG copper wire to 

terminals 13 and 14. Torque the terminal screws to 3.54 in-lbs (0.4 Nm).

8.4 Function label

Remove the plastic function label (taped inside the cover), mark as required, remove

backing strip and apply to the recessed area above the switch. Close the cover and

tighten the cover screws.

8.5 Receptacle HP Rating

9 Receptacle Wiring

Open the terminal cover and connect + 75 °C or greater copper supply wires. 

The supply side of the terminal block accepts up to two wires which are between 

6 through 2 AWG per terminal.

Allow proper length for bending and cut the conductors to length.

Strip the conductor insulation 1″(25 mm) from the end.

Insert the conductors into the appropriate terminals which are marked to 

correspond with the markings on the plug.

Torque all terminal screws to 54 in-lbs (6 Nm); including all unused terminals.

Figure 1.

10.1 Cord type

Select a flexible cord with copper conductors of the appropriate insulation, 

ampacity and + 90 °C temperature rating. For installations in the U.S., refer to the 

National Electrical Code Articles 400-4, 400-5A, 400-5B, 501-11, 502-12 and 503-10. 

For installation in Canada, refer to CEC Sections 4 and 18.

10.2 Cord preparation

Cut the cord cleanly - Do not strip away cord jacket or conductor insulation at this time.

10.3 Opening the plug

Referring to Figure 1 above, loosen screws ①and pull the plug body ②out of the 

shell ③. Loosen the screw ④on the locking clamp ⑤, insert the screwdriver in the 

locking clamp slot, lift the locking clamp out of the pressure ring ⑥and unscrew the 

pressure ring.

10.4 Insert the cord

Slide the pressure ring ⑥and the washer ⑦over the cord (Y).

Install the cord grommet. The grommet ⑧is an universal onion ring style which

accommodates several cord diameters by removing (cutting out) the inner undersized

diameters. The grommet should fit snugly on the cord. The grommet may require

lubrication in order to slide over the cord. Use talcum powder or an equivalent material

rated for use on electrical products. Slide the grommet over the cord with the cuts 

toward the shell ③.

Slide the shell ③over the cord (Y).

10.5 Cord preparation

Dress the cord by removing the outer jacket and fillers for a length of 3-1/8″(80 mm) 

and strip the insulation off of the conductors 5/8″(17 mm) from the end.

Note: Maximum range for plug terminals is 10-6 AWG. 

Tighten terminal screws to 26.5 in-lbs (3 Nm) torque.

Note: If the grommet slides freely over the cord, there will be insufficient

sealing for Class II and Class III Hazardous Locations.

10.6 Connection to terminals

Open the strain relief clamp screws ⑩and flip the clamp to the side. Attach the 

leads to the appropriate terminals ⑪. Terminal markings correspond to receptacle 

terminal markings.

10.7 Strain relief

Adjust the strain relief clamp ⑩to slide over the cord (Y). If necessary, remove the

clamp‘s plastic inserts to fit the plug body ②. Then tighten the strain relief clamp ⑩.

10.8 Plug assembly

Insert the plug body ②into the shell ③. To align the plug body ②with the shell ③, 

the keyway (X) on the inside of the shell must mate with the rib in the plug body.

Tighten the screws ①.

Slide the grommet ⑧and the gland washer ⑦forward until they shoulder against 

the shell ③and tighten the pressure ring ⑥until a good grommet compression 

is achieved.

Reinstall the locking clamp ⑤and tighten the screw ④.

10.9 Optional dust cap

The optional dust cap (P/N 85 798 01 14 0) must be used for Class II 

Hazardous Locations.

11 Commissioning

Before commissioning into service

Make sure that the device is not damaged.

Make sure that the device is installed correctly.

Remove any foreign objects from the device.

Check the tightening torques.

12 Maintenance

These receptacles and plugs require no maintenance other than a periodic inspection for

damage and proper operation. Any damaged equipment should be replaced promptly to

ensure the electrical safety and explosion protection of the system.

13 Disposal

The national and local waste disposal regulations have to be observed.

WARNING

The Equipment Ground (green wire) is to be connected to the terminal marked with the

Ground (Earth) symbol .
