Installation & Maintenance Instructions for ECP/NCP Model “E”

U-Line® Plugs

RETAIN THIS INSTRUCTION SHEET FOR FUTURE REFERENCE. For safe installation and operation, please read these instructions

carefully and with full understanding.

Compliance & Ratings

UL 1203

Class I, Group B, C; Class II, Group F, G; Class III

Electrical Ratings

Maximum Voltage: 125 V or 250 V; Current: 15 A or 20 A; Conﬁguration: 2W, 3P

Applications

• Locations where receptacles are used with stationary or portable electrically operated devices such as lighting systems, conveyors,

heaters, motor-generator sets, air conditioners compressors, and pumps.

• Locations where damp or corrosive conditions are encountered.

• Class I classied areas such as petrochemical plants, petroleum reneries, paint and chemical plants or any location where

ignitable vapors or gases are present.

• Class II locations such as process industries where there are dust hazards from handling such products as our, grain, and starch

or any location where ignitable amounts of dust are present or amounts which would otherwise affect performances.

Installation

WARNINGS

• Electrical power must be turned OFF before and during installation and maintenance. Failure to do so may result in serious or fatal

injuries due to electrocution.

• Use cable diameters ranging from 0.538 to 0.639 inches. Failure to do so may result in overstressed wire terminations, which may

cause the conductors to pull out of the contacts and cause serious/fatal injuries due to electrocution.

• Care must be taken not to cut into the individual conductor insulation when removing the outer cable jacket and to not damage the

conductors when removing individual wire insulation. Failure to do so will seriously degrade the electrical properties of the cable

and may produce overheating/electrical hazard leading to electrocution.

CAUTION

Before starting the installation, ensure the plug assembly is suitable for the intended location according to the National Electrical Code

or Canadian Electrical Code. If the plug assembly is not suitable, serious damage and injuries may result. Owners are responsible for

damages or injuries if these rules are not followed.

NOTICE

The plug should be wired with three-conductor, rubber-covered #12 AWG – #14 AWG Type SO or SOOW Cords with copper

conductors only.

Installing & Wiring

1. To disassemble the device, loosen (do not remove) the two front retaining screws from the plug and remove the plug base assembly

from the plug housing.

2. Remove plug base and insulator clamp from the plug housing. Note orientation of insulator clamp before complete removal.

3. Remove the four clamp screws from the insulator clamp.

4. Slide plug housing over cord. The self-sealing neoprene bushing will adjust to the cord diameter.

5. Strip the cable jacket and individual conductors as below:

6. Fasten the individual conductor wires to the proper terminals (in the plug base assembly) as follows:

For 125 V: GREEN wire to lug terminal “G”. For 250 V: GREEN wire to lug terminal “G”.

(terminal with grounding strap) (terminal with grounding strap)

WHITE wire to lug terminal with WHITE DOT. Other two wires to remaining lug terminals.

BLACK wire to remaining lug terminal.

Tighten the terminal screws to a torque of 15 in.-lb.

7. Slide insulator clamp down the cord and position over terminals. The insulator clamp has two slots which engage with the arc

barrier walls, providing proper orientation. Continue to slide the insulator clamp over the cord until it seats against the plug

base gasket.

NOTE: Conguration of the plug housing is such that the plug base assembly and insulator clamp assembly can only be installed

in one position.

8. Place the cord clamp according to the cable diameter (0.538–0.639 inch) and tighten the four clamp screws to a torque of 15 in.-lb.

NOTE: DO NOT attempt to over-tighten the screws or bottom the clamp.

9. Slide the plug housing over the insulator clamp assembly and tighten the two retaining screws.

Electrical Testing

All wiring must be checked and tested to ensure that all circuits are according to plan and that there are no unwanted opens, shorts,

or grounds.

Do not apply power until the following steps are complete:

1. Test the continuity of wiring to verify the correct phasing and grounding connections.

2. Measure the insulation resistance to ensure that the system does not have any short circuits or unwanted grounds.

Maintenance

WARNING

Electrical power must be turned OFF before and during installation and maintenance. Failure to do so may result in serious or fatal

injuries due to electrocution.

Electrical and mechanical inspection of all components must be performed regularly. It is recommended that inspections be performed

once a year (minimum).

In addition to these required maintenance procedures, we recommend an Electrical Preventive Maintenance program as described in

the National Fire Protection Association Bulletin NFPA No. 70B.

WARNING—MODIFICATIONS

Do not modify these devices in any way. Replace any missing or broken parts with proper Appleton replacement parts. Modication of

these devices or substitution of parts with non-standard parts may result in serious or fatal personal injury from electrocution.

WARNING—PRODUCT DAMAGE

If any part of the plug appears to be missing, broken, or show signs of damage—discontinue use immediately! This condition could

cause serious or fatal personal injury due to electrocution and/or equipment damage. Repair with the proper Appleton replacement

part(s) before continuing service.

During the inspections, perform the following steps:

1. Inspect all contact wire terminals for tightness and retorque if necessary. NOTE: Discoloration due to excessive heat is an indicator

of potential issues and should be throughly investigated and repaired as necessary.

2. ECP Plugs: Check grounding and bonding for correct installation. Secure connections and retorque if necessary.

3. Check gaskets for deterioration and replace if necessary.

4. Clean exterior surfaces to ensure the nameplates remain legible.

5. Inspect cable grip tightness to ensure proper cord/cable gripping.

6. Torque all screws as described in the “Installation” section before reusing the device.

7. Inspect all parts and replace those which are broken or excessively worn.

8. Check the contacts for signs of excessive arcing or burning and replace if necessary.

Features

• Solderless lugs on all terminals are pressure-type to facilitate wiring.

• Heavy-duty cable grip exceeds UL Standard 1203, 150 lb. pull-out test for classied locations.

• Twisting plug locks in place and cannot be accidentally pulled out.

• Longer plug housing for better gripping and easier plug insertion/withdrawal.

• Special neoprene plug bushing accommodates exible cord ranging from 0.538 to 0.639 inch diameter.
