1. According to the CEC wiring code, connectors with metric threads are only suitable for Areas Classified in ZONES unless fitted with an approved Metric to NPT thread conversion adaptor.

2. Wiring method for type of cables that can be used in Class I, Div. 1, 2, and Class I, Zone 1, 2, Classified Areas according to 60079-14 installation wiring method restrictions.

3. Shipboard Cables are for use on Marine Platform or shipboards only and are subject to local authorities having jurisdiction on the installation.

4. CAUTION – To reduce the risk of flame propagation, fittings with ISO metric threads require:
   • 5 full threads engaged for gas groups C and D
   • 10 full threads engaged for gas groups A and B

5. When the connector is supplied with metric entry threads, a CMP Entry Thread Washer should be fitted between the connector and the enclosure to prevent the ingress of moisture or dust into the enclosure. Thread tape must not be applied to the threads.

6. Before installing the connector, ensure that the connector thread forms and the enclosure thread form are compatible.

INSTALLATION INSTRUCTIONS FOR CABLE GLAND

CABLE GLAND COMPONENTS

1. Compound
2. Entry Item
3. Compound Tube
4. Spacer
5. “O” Ring| 6. Main Item
7. Skid Washer
8. Outer Seal
9. Outer Seal Nut
---|---

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING THE INSTALLATION

1. Separate the gland components by removing the main item (6) and outer seal nut assembly (7, 8, 9). Slacken the outer seal nut slightly to relax the seal and pass the main item/outer seal nut assembly over the cable, nut end first.
2. Strip the cable sheath by a length to suit the equipment. Position the end of the sheath in line with the main item (6) as shown below and tighten the outer seal nut enough to hold the cable in position.
3. Remove any bedding or fillers from around the cable cores. If the cable cores have screens, these should be unravelled and then twisted together to form a single core. Wearing the protective gloves supplied, mix all of the two-part expoxy compound until it is pliable and an even colour is achieved. (Minimum mixing temperature 10°C / 50°F)
4. Fit the tube spacer (4). Seperate the cable cores and apply the compound to the crutch of the cable for a distance of about 6mm and pack into place. If a drain wire is present then it should be sleeved using some heat shrink tubing which is pushed into the compound before shrinking with the application of some heat. If screens have been twisted together at stage 3, then they should be treated like a drain wire.
5. Bring the cores together again and pack more compound around them to a length and diameter sufficient to fill the compound tube, ending in a taper.
6. Pass the compound tube (3) over the conductors until the stepped end is fully located with the tube spacer (5). Pack more compound into place until the compound tube is fully filled.
7. Slightly slacken the outer seal nut. Re-install the cable assembly into the entry item making sure the compound is not disturbed and fully tighten the main item (6) onto the entry item (2). Tighten the outer seal nut (9) until it comes to an effective stop.
   This will occur when:
   A) The outer seal nut (9) has clearly engaged the cable and cannot be further tightened without the use of excessive force by the installer.
   B) The outer seal nut (9) is metal to metal with the main item (6).

Do not disturb for at least 24 hours
