Thermo Scientific APEX 100 User Manual page 285

Caution
Externally connected appliances shall comply with their relevant safety requirements.
Please ensure appliances (such as solenoids and photo-eyes) are rated for the voltage
they will be connected to and the field wiring into the search head is appropriately rated
in terms of current and insulation.
Caution
Ensure that AC power (mains) supply fluctuations do not exceed ± 10% of the nominal
voltage.
Caution
Do not install the APEX in a position that makes it hard to use the AC mains isolator.
Note: The normal level of transient over voltages is impulse withstand (over voltage)
category II of IEC 60364-4-443.
Note: Elsewhere in this manual are instructions for correct termination of cables. The
APEX does not use plugs and sockets for connection of external field wiring. If such a
method is required, contact Thermo Fisher Scientific—as described in the "Contacting
Thermo Fisher Scientific" section at the end of the manual—for recommended methods.
Supply Voltage and Connections
Given below are the requirements for the voltage supply and connections to your APEX
detector.
• Input supply voltage range should not be outside the range 85VAC to 264VAC.
• We recommend the APEX be fed from a clean AC supply and left powered.
• Connections are made inside the control panel on the PSU PCB. Do not "tee" off
with wiring for other external electrical equipment (even other metal detectors).
• When choosing the AC power line for the detector, note that starting heavy
electrical machinery can create considerable (though momentary) volt-drops in
the line. This can cause the detector to trigger. Since detector power
consumption is only 35 watts, it is recommended that a lighting circuit be used
rather than machinery power circuit. Where this is not possible and line noise
triggers the detector, contact Thermo Fisher Scientific—as described in the
"Contacting Thermo Fisher Scientific" section at the end of the manual—for
recommendations about a suitable isolation transformer or power-line filter.
Note: Do not use loads requiring power sources not generated or used by the APEX,
unless approved by Thermo Fisher Scientific.
