ASSEMBLY INSTRUCTION DETAILS
Note:
CMH cable may be terminated in any enclosure certified for the application.
When using a non-metallic enclosure use a hub with a grounding lug.
1. Megger the insulation resistance between the sheath and conductors. The reading should be 20 MOhm or higher
prior to installing the cable. After thermal insulation is installed on the pipe ensure the megger reading is 5 MOhm
or higher
Note:
CMH Cable is a zone type cable. Refer to CMH Cable Reference Chart at the back of these instructions.
2. Using a hacksaw, cut the desired length of CMH cable allowing an extra three (3) feet (1 m) per end and
appropriate cable length for heat sinks such as valves, flanges and pipe supports.
3. Using a CMH Stripping Tool, strip the sheath back 12" (30.4 cm) from the raw end, remove and discard. This
exposes the core to locate the zone node.
Note: If the cable has two-foot zones you may have to strip back up to 24" (60.8 cm). Refer to chart on page 4.
Zones nodes can be identified by the indent in the core. Strip back the insulation to expose and confirm the
location of the node
Note: If using a hacksaw cut around the sheath being careful not to damage the core.
4. From the node measure 14" (35.5 cm), mark the sheath and strip the sheath to the mark. Discard the sheath.
Wrap a layer of electrical tape around the core, next to the sheath, to prevent the insulation from unwrapping
into the sheath.
