CHAPTER 1: SAFETY INFORMATION This Safety section contains important instructions that should be followed during installation and maintenance of the APC equipment and batteries. It is intended for APC customers who setup, install, relocate, or maintain APC equipment. Connection to the branch circuit (mains) must be performed by a Licensed Electrician. Installation and removal of the Power, Battery, and Intelligence modules must be performed by service personnel.
• Use one hand, whenever possible, to connect or disconnect signal cables to avoid a possible shock from touching two surfaces with different electrical grounds. • Connect the equipment to a three wire AC outlet (two poles plus ground). The receptacle must be connected to appropriate branch circuit/mains protection (fuse or circuit breaker). Connection to any other type of receptacle may result in a shock hazard.
Recycling of Batteries See your dealer or Replacing Modules in the SYMMETRA RM OPERATION MANUAL, for information on replacement battery kits and battery recycling. • Do not install the battery module(s) in the frame until you are ready to power up the Symmetra RM. Failure to so can result in a deep discharge of the batteries, which may cause permanent damage. • Store the battery module(s) in a cool ambient temperature of < 25 °C.

CHAPTER 2: BASICS About Your UPS The Symmetra RM is a high-performance, uninterruptible power system in a “power array” configuration, designed to power high availability servers and other sensitive electronic equipment. It provides conditioned, reliable AC power to connected equipment, and provides protection from power blackouts, brownouts, swells, sags, surges, and interference. The Symmetra RM is comprised of a frame and a variable set of modules.

Product Overview Front View Component Identification Figure 2: Front View of the Symmetra RM Power Module(s) : The Symmetra RM can support between one and four power modules. Each module provides 2 kVA/1.4 KW power. Redundant Intelligence Module : The redundant intelligence module (RIM) is a backup version of the main intelligence module(MIM). It provides redundancy in the event of a MIM failure or while a MIM is being replaced.
Rear View Component Identification Figure 3: Rear View of the Symmetra RM (200/208 Vac / L1-L2-G version shown) System Fan : The system fan can be replaced in the field. Refer to Replacing the System Fan, in the SYMMETRA RM OPERATION MANUAL, for instructions. Accessory Ports : APC manufactures a set of auxiliary user interface accessories. The Symmetra RM contains a total of three accessory ports.
Input Voltage Selection Switch : Set this switch to the appropriate setting, either 200/208 (L1-L2-G) or 220/230/240 (L1-N-G) before powering up the Symmetra RM. Products rated 200/208 are typically installed in North America (208 V, phase to phase, grounding conductor) and Japan (200V, phase to phase, grounding conductor). Products rated 2020/230/240 are typically installed in the rest of the world (220 V, 230 V, or 240 V, phase to neutral, protective earth).

CHAPTER 3: INSTALLATION Unpacking APC has taken care to design robust packaging for your product. However, accidents and damage may occur during shipment. Inspection Inspect the UPS upon receipt. Notify the carrier and dealer if there is damage. The packaging is recyclable; save it for reuse or dispose of it properly.
Determine the Location of the Symmetra RM in the Rack 1. Select a location for the Symmetra RM in your NetShelter enclosure or other 19-inch (46.5 cm) rack. Select a location with adequate air flow that is free from excessive dust. Ensure that the air vents on the sides of the Symmetra are not blocked. • The Symmetra RM is heavy. Select a rack location sturdy enough to handle the weight. Mount the unit at or near the bottom of the rack.
Install the UPS into the Rack 1. With two people supporting the Symmetra RM, one on each side, carefully align the cleats on the sides of the unit with the grooves on the mounting rails. Slide the unit into the rack completely. 2. Use the six (6) ornamental screws, supplied with the unit, to attach the mounting brackets to the rack post.
1. Make sure the main circuit breaker , located on the rear panel, is in the OFF position. 2. Select the appropriate wire size and connectors, according to local codes. For most applications, #10 AWG (5 sq. mm) wire should be sufficient. 3. Remove the input wiring access door by unscrewing the single screw that holds the access panels in place. The input wiring terminal is located on the rear panel of the Symmetra RM. 4.
Use one of the following cable types to connect the Symmetra RM to the EPO switch: CL2 Class 2 cable for general use. CL2P Plenum cable for use in ducts, plenums, and other spaces used for environmental air. CL2R Riser cable for use in a vertical run in a shaft of from floor to floor. CL2X Limited use cable for use in dwellings and for use in raceway. For installation in Canada: Use only CSA Certified, type ELC (extra-low voltage control cable). Connection Option 1 An electrician must connect 1 to 2.
Install battery modules just prior to running the Symmetra RM. The battery modules discharge slowly when loaded prematurely and can be damaged permanently. Each battery module weighs 21.8 kg (48 lbs). Two people are required to install or remove battery modules. Battery Module: With one person on either side of the battery module, lift the module, and slide it completely into the frame to engage the internal electrical connector.
APPENDIX A: ELECTRICAL WIRING CHECKLIST Complete this checklist to ensure that the Symmetra RM has been wired properly. Ensure that all switches (system enable, maintenance bypass, input circuit breaker, and bypass circuit breaker) are in the Off or Stand By position. Turn off or unplug all equipment connected to the Symmetra RM. Ensure that the input voltage selection switch is in the appropriate position. 1. Apply power to the system input. Measure the voltage at the input terminal block.
5. Record input voltages below and compare the values with the measured voltages from step 1. If the two measurements are significantly different, contact APC Symmetra technical support. Vin 1: ________________________________________________________ 6. Switch the maintenance bypass switch on. Disregard any LED indicator or fault messages on the PowerView. Record the output voltage, below, and compare the value with Vin 1 from step 5.
