Core security standards
4.1 Electrical Safety (Warning Level)
Power requirements
Designated power cords must be used, with voltage matching the rated value of the instrument (100-240VAC). Exceeding the maximum voltage of the power cord (such as UL/CSA 125V, VDE 250V) is prohibited
The power plug must be inserted into a three core socket with protective grounding, and the use of ungrounded extension cords is prohibited
grounding protection
Before starting up, it is necessary to connect the protective ground and it is forbidden to cut off the internal/external grounding wire
Check if the grounding and fuse are intact. Do not operate if they are damaged
Operation taboos
Prohibited for use in explosive gas/vapor environments
It is prohibited to dismantle the casing (including high-voltage components inside) without authorization. Only qualified personnel from Yokogawa can repair it
Before connecting external equipment, it is necessary to ground it first. Before touching the circuit, turn off the power and confirm that there is no voltage
4.2 Laser Safety
Laser classification and standards
Module model: Laser classification meets key protection standards
AQ2200-112/131/132 Class 1 IEC 60825-1:2014, 21 CFR 1040.10/11 prohibits direct viewing of laser beams
AQ2200-111/141/142/136 Class 1M IEC 60825-1:2007, 21 CFR 1040.10/11 prohibits the use of optical instruments (magnifying glasses, etc.) for observation at<100mm
Laser unlocking process
Connect the included interlock plug (A1288JA) to the Remote INTERLOCK interface behind the frame controller
Press the SYSTEM key to enter the system screen, move the cursor to Lock, and press ENTER
Enter the default password '1234' and press ENTER
Set Lock to Off and press OK to confirm (laser output can only be turned on after unlocking)
4.3 Environmental Protection and Compliance
WEEE Directive (EEA and UK): Prohibition of mixing household waste, contact local Yokogawa office for disposal
Battery Directive (EEA and UK): Lithium batteries must be collected separately and replaced. Contact the local Yokogawa office for replacement
RoHS compliance: The instrument itself complies with EU RoHS, but if incompatible modules (such as AQ2200-111, AQ2200-131, etc.) are installed, it becomes invalid. The list of incompatible modules can be found in Section 5.1

Operation process guide
5.1 Module installation and uninstallation
Installation steps
If there is a blank panel in the slot, loosen the screw → slide down to remove the panel
Press the unlock button on the module panel and lift the locking lever
Align with the slot guide rail and slowly insert the module until it is fully seated
Slowly press the lever until you hear a "click" sound (2/3 slot module needs to tighten the bottom fixing screw)
Uninstalling steps
If it is a 2/3 slot module, first loosen the bottom fixing screw
Press the unlock button and gently lift the lever to unlock
Slowly pull out the module (protrude about 1cm, then pull it out by hand)
Hot swappable instructions: Modules can be installed/uninstalled while the frame controller is turned on. If a non SUMMAY/DETAIL screen is displayed during uninstallation, it will automatically switch to these two screens
5.2 Cable Connection
Fiber optic connection
Cleaning the fiber optic end face: Soak the cleaning paper in isopropanol, press and rotate the end face to wipe, then dry it with dry cleaning paper, and finally blow away residual dust with compressed air
Connection rule: The ANGLED PC ONLY interface is only connected to APC type fiber optic cables and is prohibited from connecting other types (to avoid damaging the plug)
Connector adapter: such as AQ9441 (for FP-LD module), AQ9335C (for sensor module), align the guide pin/hole connection according to the manual steps, and lock the lever
electrical connection
Coaxial cable: used for modules such as BERT and optical modulators. Before connecting, confirm that the signal output is turned off and tighten the connector with a torque of 0.9N-m
Power cord: Confirm that the instrument switch is turned off, connect it to a three pin grounded socket, and ensure that the voltage matches the rated value
Key module connection example (BER test)
BERT module (AQ2200-601) DATA OUT → Optical modulator (AQ2200-621/622) DATA IN
Light modulator LD IN → Light source module (AQ2200-111 PMF type) laser output
Optical modulator OPT OUT → DUT → Optical receiver (AQ2200-631) OPT IN
Optical receiver DATA OUT → BERT module DATA IN 1 (CDR)
