Connect Power Supply

Before beginning the power supply installation, take note of the following safety specifications:

  • Any line-connected, single-pole switch with a marked OFF position shall be connected to a TERMINAL or lead intended for connection to the ungrounded conductor of the supply circuit.

  • Over-current protective devices shall be connected to the ungrounded supply connector.

  • A switch or circuit-breaker must be included in the installation.

  • The switch must be suitably located and easily reached.

  • The switch must be marked as the disconnecting device for the equipment.

  • A multiple-pole circuit breaker shall interrupt all neutral and ungrounded connectors of mains supply simultaneously.

  • Equipment intended for permanent connection to the mains shall have provisions for connection of a wiring system in accordance with ANSI/NFPA 70, NEC, with CSA C22.1, CEC, Part I or with both, as appropriate.

Complete the following steps to install a power supply for the RM4150 or RM4151. Refer to RM4150 and RM4151 Unit Overview for location of the power input connector.

  1. Mount the AC/DC power supply. Typically, the power supply installs inside the rectifier enclosure.

  2. Connect the power supply's AC Input wires to the AC power source (neutral, white to white; and hot, black to black).

  3. Connect the power supply's DC Output wires to the DC INPUT connector on the unit (refer to RM4150 and RM4151 Unit Overview for location of connector).

The RM4150 and RM4151 make a clicking sound after turning on the power switch. This is a normal function and indicates the unit is polling input channels.
