ENGLISH
Please read all instructional literature carefully and thoroughly before starting. Refer to the inside front cover for the listing of Liabilities and
Warranties. NOTICE: The information contained in this document is subject to change without notice. Please read these Operating Instructions
before Commissioning the thermostat. Keep the operating instructions in a place which is always accessible to all users. Should any difficulties
arise during start-up, you are asked not to carry out any unauthorized manipulations on the instrument as this could affect your warranty rights.
Please contact the nearest nVent subsidiary or the head office. If any servicing is required, the instrument must be returned to the head office.
Specific conditions of use
1. Cable entry shall be through rated conduit hubs to maintain the ratings of the enclosure provided.
2. Unused cable entries must be filled with suitable rated conduit plugs maintaining the environmental ratings of the enclosure.
3. Leads connected to the terminals shall be insulated for the appropriate voltage and this insulation shall extend to within 1 mm (1/32") of
the metal of the terminal throat.
4. The maximum permitted current of the alarm contacts is 2 A, and the maximum permitted voltage is 277 Vac
5. The earth pillar adjacent to the RTD connectors must be used only for RTD cable screens.
6. The external RTDs must be capable of withstanding a 500 V test to earth.
Area of use
nVent RAYCHEM Elexant 3500i thermostats are used for temperature control of electrical heating cables in industrial environments.
Alternatively they can be programmed to act as a temperature limiter. The Elexant 3500i consists of a temperature controller but can
alternatively be programmed to act as a temperature limiter. Elexant 3500i electronic modules are approved for use in ordinary and Class I
Division 2 Groups A,B,C,D and are required to be installed in an Elexant 3500i enclosure or approved Type 4 enclosure. Elexant 3500i units
consisting of an Elexant 3500i electronics module and Elexant 3500i enclosure are approved for use in ordinary and Class I Division 2 Groups
A,B,C,D and Class II Division 2 Groups F,G.
Safety instructions
During operation, do not leave this Instruction Manual or other objects inside the enclosure. Use the temperature controller or limiter only for its
intended purpose and operate it only in clean, undamaged condition. Do not make any modifications to the temperature controller or limiter that
are not expressly mentioned in this Instruction Manual. If the Elexant 3500i is used in a manner not specified by nVent, the protection provided
by the equipment may be impaired. Whenever work is done on the temperature controller or limiter, be sure to observe the national safety and
electrical code requirements and accident prevention regulations and the safety instructions given in this Instruction Manual.
Description
The Elexant 3500i electronic thermostats are Type 4X rated connection kits. They are designed for use with nVent RAYCHEM industrial heating
cables.
When powering mineral insulated (MI) circuits, cold leads must be used, accounting for MI cold lead cable gland size, hub size and power
cable size. Power cable gland and hubs for MI cold lead glands are not included.
The kits can be used to connect one or two heating cables to power. The Elexant 3500i power terminals are rated for a single copper
conductor up to wire size 25 mm2 (4 AWG), or they may accept 2 copper conductors of wire size 6 mm2 (10 AWG) in 1 terminal with the use of
a twin ferrule.
Note: For two heating cables powered by a single circuit, the length of each heating cable should not exceed the maximum allowable
circuit length published in the nVent RAYCHEM self-regulating cables design guide and the total current of all heating cables on the
circuit should equal no more than 80% of the circuit breaker current rating. These kits may be installed at temperatures as low as –67°F
(–55°C). For easier installation store above freezing until just before installation. For technical support call nVent Technical Support
Department at (800) 545-6258.
