The following limiting temperatures for the end seals, splices and power
connections shall not be exceeded:
+110°C for the S-20 and E-20
+260°C for the E-40 and S-40
+150°C for the C-150-E, S-150 and E-150
+151°C for the E-100, E-100-L and JBS-100
+155°C for the JBM-100 and T-100
+110°C for the C25-21 and C25-100
+180°C for the C25-100-METAL/C3/4-100-METAL
The E-100, E-100-L, JBM-100, JBM-100-L, JBS-100, JBS-100-L and
T-100 have limiting temperatures based on an internal component in
these accessories. When located on a pipe or other work piece surface,
a maximum pipe temperature of 250°C will not cause the limiting
temperatures of 151°C or 155°C to be exceeded
The end seals, splices and power connections have the following
associated ambient temperatures:
–60°C to +56°C for the E-20 and S-20
–60°C to +56°C for the E-40 and S-40
–55°C to +56°C for the T-100, JBM-100, JBS-100, JBU-100 and E-100
–40°C to +56°C for the JBS-100-L, JBM-100-L, and JBU-100-L
–55°C to +55°C for the C-150-E, S-150 and E-150
–40°C to +40°C for the E-100-L
–55°C to +110°C for the C25-21 and C25-100
–60°C to +180°C for the C25-100-METAL / C3/4-100-METAL /
C25-100-METAL-NP / C3/4-100-METAL-NP / C25-100-METAL-SS
• The assembly of glands, splices and end terminations
shall be carried out in accordance with the manufacturing
instructions.
• The heating element supply circuit must include an electrical
protection device in conformity with Clause 4.4 of IEC
60079-30-1. For the JBM-100-L, JBU-100-L and JBS-100-L
this shall be limited to 20A maximum when used at ambient
temperatures above 40°C.
• The minimum installation temperature of the heating
cables is –60°C. The minimum bending radii at specific
temperatures are shown on the next pages of this document.
• The supply to the heating unit must be terminated in a
suitably certified terminal enclosure.
• At ambient temperatures above 40°C temperature resistant
power cable suitable for temperatures above 90°C and metal
glands must be used.
• The minimum installation temperature for E-20 and S-20
is –20°C.
• The installer is to carry out a dielectric strength test on
Ex equipment in which the C25-21, C25-100 and C25-100-
Metal / C3/4-100-Metal / C25-100-Metal-NP / C3/4-100-
Metal-NP / C25-100-Metal-SS connection kit is fitted. No
dielectric breakdown shall occur. (Alternatively, an insulation
resistance test may be undertaken in accordance with
IEC 60079-30-2)
