General Installation Information
Torque specications:
• M6 screws: 4.0 Nm, ±0.7 Nm (36 in.-lb, ±9 in.-lb) (to secure amepaths or
pressurized surfaces such as on the Heatsink, Filterblock, and User Inter-
face (Window Housing) faceplate).
• M10 screws: 9.0 Nm, ±0.7 Nm (80 in.-lb, ±9 in.-lb) (to secure amepaths of
the Electronics Enclosure cover and its housing).
Tools, Equipment, and Supplies Required
To install the analyzer, you need the following:
• Set of open-end wrenches for ttings.
• Set of metric hexagonal wrenches.
• Set of metric ball drivers.
• Torque wrench, calibrated, for fastening M6 and M10 screws.
• Wire Cutters, strippers, and crimpers.
• Flat blade instrument screwdriver.
• Wrist Strap (for grounding).
• Detergent-based leak detector (Snoop
®
or another suitable leak detection
agent is permissible).
• Supply of AC electrical supply cable, which must be approved by the local
wiring regulations and electrical codes for the hazardous location, and
which must be rated for minimum 80 °C (176 °F).
• One power-disconnect explosion-proof switch (breaker), rated for at
least 250 VAC, 3 A and certied for the hazardous location (to satisfy lo-
cal electrical codes, the switch must be certied by the local authority
for the appropriate hazardous location). The power-disconnect switch
(breaker) must be connected to and mounted near the analyzer, in an
easily accessible area. The switch (breaker) must be clearly labeled (e.g.,
“AMETEK241CEII Analyzer Main AC Power Disconnect Switch”). For safety
reasons during maintenance, this switch allows the main AC power to be
disconnected from the analyzer prior to performing service on the ana-
lyzer. This switch (breaker) is to be supplied by the customer/end user.
