gland. see fig. 2
Assembly of pipe mounted type fig. 02
• Mount thermostat junction box either standing or
hanging to pipe by pipestraps.
• Remove dust protection or stopping plugs and install
gland to be used. Drain is to be mounted at the lowest
point. For holes not in use, these must be inserted with
stopping plugs. Only certified cable glands and blinds
may be used. Gland has to be chosen according to
cable diameter used.
Temperature sensor
The sensor should be strapped in good thermal contact
with the pipe or equipment. In addition to general mechanical protection, the sensor should be protected so that the
thermal insulation cannot be tapped between the sensor
and the heated surface. The sensor is normally fixed to
pipe or object by use of aluminium tape. Other methods
could be thermowells suitable for the application.
MAINTENANCE/REPAIR/MODIFICATION
• Maintenance according to national regulations and
company practice.
• Before opening the junction box make sure that the

by the cable gland sealing ring. The sealing ring is not
dimensioned for the Ø1,5mm capillary tube.
Termination
In order to maintain the mode of protection, the conductors
will have to be connected with special care. The isolation
must reach up to the terminals and the conductor must not
be damaged. Termination of heat cables must be according
to cable specification given by supplier of these. Tighten
all terminals, also those vacant. Reinstall lid and tight bolts
firmly with suitable tool by hand force. Over tightening may
impair the protection category.
