Installation and safety regulations
1. Installation requirements
Module positioning: IOM needs to be plugged into the corresponding IOTA, which is fixed to the 24VDC bus power supply rail of the cabinet with screws
Wiring specifications:
Wire specifications: It is recommended to use copper wire with a rated temperature of 75 ℃, and a single terminal can support 2 wires of the same specification or 1 maximum 12AWG wire
Stripping length: Unified at 0.25 inches (7mm), excessive length may result in exposed wires and pose a risk of electric shock
Noise protection: Ensure that the module installation screws are tightened and grounded according to specifications; The noise reduction gasket on the right side of the module (both sides of the power module) should be in contact with adjacent modules/cabinets to avoid electromagnetic noise interference
2. Installation requirements for hazardous areas
For Class I Zone 2 hazardous environments, the following regulations must be followed:
Only applicable to Class I Zone 2 A/B/C/D hazardous areas or non hazardous areas, and cannot be used for other hazardous level scenarios
It is prohibited to replace module components, otherwise it may damage the explosion-proof applicability
Before power outage or confirming the safety of the area, it is forbidden to disconnect the equipment connection to avoid the risk of explosion

Ordering Information (Core Components)
In addition to the IOM module, matching IOTA and fan components need to be selected based on the number of cabinet slots and power supply type. Some key models are as follows:
