Mechanical Installation - nVent RAYCHEM Elexant 5010i Installation Instructions Manual

1. INSTALLATION
For installation/operation, always observe the Equipment Safety Law, the rules of generally accepted engineering practice
(IEC60079-14/EN 60079-14), and the instructions stated in this Manual. Carry out work on the thermostats in the de-energized state only.
1.1 Mechanical installation
Elexant 5010i-LIM units comprise a temperature controller and a safety temperature limiter installed in one enclosure. The controllers
can be installed in any position on a stable structure by means of the 4 mounting holes. Up to a pipe temperature of 210°C the
Elexant 5010i and Elexant 5010i-LIM units can be mounted directly on the pipe by means of a support bracket type SB-125. Ensure that
the ambient temperature of the equipment does not exceed 60°C at any time. In order to provide enough stability, the support bracket
shall be attached by means of 2 pipe straps.

Tolerance class for Ex e glands is maximum 6G/6H.
When plastic glands are used, only plastic glands made from flame retardant, high
impact resistant polyamide shall be used. The glands shall be suitably certified for the
intended area of use.
Better than 3,2µm is recommended.
Maximum level of surface roughness allowed is Ra 6µm;
