Ensure suitably rated power supply cables and glands are used to ensure that electrical safety is
maintained. Connect to the POWER IN each of the Live (L), Neutral (N) and Earth [Ground] (E)
conductors to the similarly marked terminals (L, N, E). Ensure the power supply can deliver sufficient
power consumption requirement.
Ensure any power supply terminals and voltages are suitably separated from the other I/O
requirements of this product.
Before applying power, perform a continuity test to ensure that the power supply cable and product
are effectively connected to the protective Earth.
The product enclosure is supplied with an external Earth stud at the lower right hand side. At
installation, connect this Earth stud to plant Earth by a minimum 4mm2 earthing bonding.
Fuse – A replacement fuse can be obtained by contacting Michell Instruments' technical support.
Michell order number – XTC601-26149.
This product is designed to operate, as a minimum, between a temperature range of -5 to +40°C (+23
to +104°F), in maximum 80% relative humidity for temperatures up to +31°C (+87°F) decreasing
linearly to 50% RH at 50°C (122°F). Supply voltages of ±10% and transient over voltages up to
Overvoltage Category II. Pollution Degree 2. Altitudes up to 2,000 meters. Outdoor mounting is
permitted using suitably rated glands equivalent to NEMA 4 / IP66. See Technical Specifications
(Appendix A) in this manual for full operating parameters. Do not remove or exchange any of the
cables or electrical components supplied with this product. To do so will invalidate all warranties. There
are no additional or special electrical safety requirements other than those referred to in this manual.

area.
WARNING:
This product must not be operated within an explosive
atmosphere greater than 1.1 bar absolute.
WARNING:
This product must not be operated outside of
the temperature range of -40 to +55°C (-40 to +131°F).
Pressure Safety
WARNING:
This product is used in conjunction with pressurized gases.
Observe pressurized gas handling precautions.
WARNING:
Pressurized gas is dangerous.
Pressurized gas should only handled by suitably trained
personnel.
The XTC601 measurement chamber requires pressurized gas to be connected to it. Observe
pressurized gas handling regulations. Suitably trained personnel only should carry out tasks that
include the use of pressurized gas mediums.
DO NOT permit pressures greater than the safe working pressure to be applied to the instrument.
The specified safe working pressure for this instrument is 1 barg (14.5 psig) max.
Temperature Safety
During operation some internal parts of the instrument may be at high temperature.
