AIM-R100 Residual Current Monitoring Product
1 Introduction
Residual current monitoring products are suitable for medical class 2 and class 1 places and other places that
need to monitor the residual current, mainly used for monitoring the residual current of TN-S distribution system
mains and branches. When the residual current value exceeds the preset threshold, the system will send an alarm
signal to remind the staff to deal with it according to the actual situation, so as to eliminate the potential safety
hazards such as electrical fire and electric leakage shock caused by the residual current and provide clean, safe and
continuous power supply for the equipment. The residual current monitoring products are also the monitoring
instruments developed by Acrel with rich product design experience and strict reference to the requirements in the
standards and specifications. The product conforms to the enterprise standard Q31/0114000129C025-2017
Residual Current Monitoring Device.
The remaining current monitoring products mainly include AIM-R100 residual current monitor, AKH-
0.66/L-20 residual current transformer, AID150 centralized alarm and display instrument and ACLP10-24 DC24V
power supply, as shown in Table 1 below.

5.2 Method of installation
In addition to the AID150 centralized alarm and display instrument, the residual current monitoring products
are best centrally installed in the distribution cabinet. AIM-R100 residual current monitor uses 35mm standard
guide rail to install, AKH-0.66/L-20 residual current transformer uses screws (attached) directly fixed installation.
When the AID150 centralized alarm and display instrument is used in the operating room, it can be embedded in
the wall and installed next to the information panel in the operating room for medical personnel to view; When
AID150 is used in other medical places, it is recommended to install in the nurse station. It can also be installed in
other locations that are easy to monitor. External wiring of the AID150 centralized alarm and display instrument
includes two DC24V power supply lines and two RS485 communication lines, which are drawn from the
distribution cabinet. Pipelines should be reserved during construction. In the centralized monitoring, the RS485
communication between the AIM-R100 and AID150 should be connected hand in hand.
5.2.1 Installation method of AIM-R100 residual current monitor
The AIM-R100 residual current monitor is installed with guide rail and fixed with buckles, as shown in the
