This document applies to service offering applications only.
SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air- conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that are attached to the equipment.

Introduction

Read this manual thoroughly before operating or servicing this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions. The three types of advisories are defined as follows:
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.
NOTICE: Indicates a situation that could result in equipment or property- damage only accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants.
Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow  requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:

• Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labeling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.

• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS) policies when performing work such as hot work, electrical, fall protection, lockout/tagout, refrigerant handling, etc. Where local regulations are more stringent than these policies, those regulations supersede these policies.
• Non-Trane personnel should always follow local regulations.

WARNING
Electrical Shock, Explosion, or Arc Flash Hazard!
Failure to follow these instructions could result in death or serious injury.

• Install the product in an appropriate electrical/fire enclosure per local regulations. Do not install the product in hazardous or classified locations.

• Do not use the product for life or safety applications.

• Do not exceed the product ratings or maximum limits.
  Products rated only for basic insulation must be installed on insulated conductors.

• Current transformer secondaries (current mode) must be shorted or connected to a burden at all times.

• Remove all wire scraps, tools, replace all doors, covers and protective devices before powering the equipment.

WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could result in death or serious injury.
Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Verify that no power is present with a voltmeter.

Components and Package

The energy meter is applicable for all Symbio™ 800 upgrade controls for Trane or customer-provided non-AFD starters.
Table 1. Main components in package

Package Number| Starter Application| Modbus RTU Power Meter| ROGOWSKI 12-inch CTs
---|---|---|---
0185-0428-0100| 480V and Low line voltage| 1| 3

Installation

Mounting

1. Energy meter is installed on a DIN rail. Locate an appropriate location in the starter panel. Install included DIN rail. Mount energy meter with strap tunnel as shown in the following figure.
2. Install three CTs (current transformers) on power line, following guidelines below:
   • Install Rogowski CTs in 600Vac or less applications only.
   • Do not install on the load side of a variable frequency drive (VFD).
   • To get the correct sign on bi-directional data, observe the load arrow (un- directional data does not care).

Field Wiring and Schematics

Wiring Installation
Note: Referenced schematics are found in section “Schematics,” p. 6.

• Terminal meter connection

• CT wiring
  Connect CTs to the energy meter r per details in schematic and the following figure.

• Stepdown transformer wiring
  Connect transformer to starter per details in schematic.

• RS-485 communication wiring
  RS-485 communications are by shielded 14 – 26 AWG cable. See the following figure.

The communications wiring will be terminated at the Modbus distribution terminal (1X3) at the Symbio™ 800 controller using the 3-pole connectors as shown in the schematic and the following figure.

Schematics

480 Volts and Lower Application
Wire Rogowski CTs in current input. Wire fused inputs to line voltage. See detail in schematic 5071-2756. Table 2. Schematic matrix

Software Setting and Configuration

1. Select power meter address as ‘15’, set CT AMPS as energy package in Table 1, p. 4.
2. Select E683 CTs as ROGOWSKI CT.
