  • Page 3: Introduction

    APPLICATIONS The ETA-20SH is designed to be flexible for use in a variety of applications. When used with a sequenced controller it allows the turning of equipment on and off from a remote location to save energy and to reduce an in-rush of current that stresses the main AC line. It also can be used as a standalone unit for protection against voltage surges and applies EMI/RFI filtering to clean up the AC...
  • Page 4 • T o prevent electric shock, do not remove the device cover as there are high voltage components inside. Refer all servicing to ETA Systems. • S hould any of the following irregularities occur during use, immediately switch off the power, disconnect the power cord from the AC outlet and contact ETA Systems. Do not to attempt to continue operation of the device as this may cause fire or electric shock. • S moke or strange smell coming from the unit. • I f the device falls or the case is damaged.

    This appliance shall not be exposed to dripping or splashing water and that no object filled with liquids such as vases shall be placed on apparatus. 17. To completely disconnect this equipment from the mains, disconnect the power supply cord plug from the receptacle. 18. The mains plug of the power supply cord shall remain readily operable.

    AC Power Conditioning & Suppression Module INTERNAL FEATURES OF THE ETA-20SH – PROTECTION BEHIND THE PANEL • E MI/RFI Filters ECM filters unwanted Radio Frequency Interference (RFI) that is commonly introduced into the AC lines by nearby radio transmitters or wireless products. EMI filters are incorporated to reduce noise from Electromagnetic Interference (EMI) produced by such items as electric motors or switching power supplies.

E xternal Trigger / Manual On Switch – The ETA-20SH has a manual override switch allowing it to be used as a local Power Conditioner and Surge Suppressor. For it to be remotely monitored and activated, the switch must be in the “External Trigger”...

    Module can be up to 1000ft. USING THE ETA-20SH AS A STANDALONE UNIT The ETA-20SH can be used as standalone unit for local equipment protection. It does not need to be connected to an ETA-ECS6RM to operate. You still get protection against AC spikes from short power surges and you get all the EMI/RFI power conditioning filtering. Without connecting to an ETA-ECS6RM, the ETA-20SH does not utilize the Extreme Voltage Shutdown (EVS) protection and the Voltage and Current Status readings.

  • Page 9: Eta-20Sh Interfaced With An Eta-Ecs6Rm Sequence Controller

    To get maximum use of the ETA-20SH we suggest using the ETA-ECS6RM controller. When the two are interfaced the ETA-ECS6RM controller not only can remotely turn on the ETA-20SH but it can monitor the AC Mains Voltage and Current of the ETA-20SH. When mated, the microprocessor in the ETA-ECS6RM can determine if there are any potentially damaging AC Voltages present at the ETA- 20SH and shut it off before damage can occur to sensitive equipment connected.

    Mounting Rails – The ETA-20SH can be mounted into most racks that have at least 12" of internal height. The housing has breakaway rail mounting tabs that make it convenient to secure the raceway in most applications. There are two rails to secure the ETA-20SH to a cabinet or wall. Multiple slots are provided for ease of installation. When mounting to a rack rail system use 10/32" x 1" screws, when...

    Possible Cause #1: Incoming AC Mains circuit breaker has tripped due to excessive load. Action Needed: Check the AC outlet that the ETA-20SH is plugged into for 120V AC voltage. If no voltage is present, check to see if the AC outlet is on a GFI and check to see if it was tripped. If it has not been tripped trace the AC Mains outlet back to the electrical panel and check the AC Mains breaker to see if it is tripped.
