3500/65 145988-02 Triple Module Redundancy (TMR)

The provided text outlines information about the 3500 Power Supplies in a monitoring system. Here are the key points:

1. Installation and Configuration:
   • The 3500 Power Supplies are half-height modules designed to be installed in specially designed slots on the left side of the rack.
   • The rack can contain 1 or 2 AC or DC power supplies in any combination.
   • Either supply can power a full rack, and if the second supply is installed, it acts as a backup for the primary supply.
   • Removing or inserting a power supply module will not disrupt the operation of the rack as long as a backup supply is in place.
2. Input Voltage Range:
   • The power supplies accept a wide range of input voltages and convert them to voltages acceptable for use by other 3500 modules.
3. Power Supply Versions:
   • Three power supply versions are available:
     1. AC Power Supply
     2. High Voltage DC Power Supply
     3. Low Voltage DC Power Supply
4. AC Power Supply and Power Input Module (PIM):
   • The AC Power Supply uses two versions of the Power Input Module (PIM) to accept two ranges of AC input voltages.
   • The High Voltage AC PIM accepts inputs from 175 to 264 Vac rms.
   • The Low Voltage AC PIM accepts inputs from 85 to 132 Vac rms.
5. Backup Supply and Independent Power Distribution:
   • When two power supplies are installed, the lower slot supply acts as the primary, and the upper slot supply acts as the backup. In case of primary supply failure, the backup supply takes over without interrupting rack operation.
   • Each supply provides power on an independent power distribution network to prevent the failure in one network from affecting the other.
6. CE Compliance and Low Voltage Directive Compliance:
   • For systems installed in areas complying with EN61000.3.2, the equipment should be used in an industrial environment with a connection to the industrial power supply network.
   • If connected to the public power supply mains, the system must meet EN61000.3.2 using a third-party device that provides power factor correction.
   • To comply with EN 61010-01 Low Voltage Directive, the PIM Connector Shield should be oriented properly. Incorrect orientation may make power terminals accessible to an operator.

This information provides details on the installation, configuration, and compliance considerations for the 3500 Power Supplies in a monitoring system. Users should follow the guidelines for proper setup and adherence to compliance standards.
