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.
Connect the Symmetra RM to its Power Source
200/208/240 Vac (L1-L2-G) Symmetra RM: The input power can be supplied in two ways: the attached line
cord can be plugged into an appropriate outlet; or the power can be hard wired. Use the line cord if the load is
5 kVA. If the load is greater than 5 kVA you must hard wire the input power.
220/230/240 Vac (L1-N-G) Symmetra RM: The input power must be hard wired.
How to Connect the Input Line Cord
If your Symmetra RM is configured for 200/208 Vac (L1-L2-G) and has a load of 5 kVA or less,
use the line cord to power the Symmetra RM. No wiring is necessary.
220/230/240
200/208
1. Set the input select switch to 200/208 (L1-L2-G).
2. Plug the standard 208 Vac L6-30 power cord into a 30 Amp
208 Vac outlet.
How to Hard Wire the Symmetra RM
Verify that all incoming line voltage (utility power) and low voltage (control)
circuits are de-energized, and locked out before installing cables or making
connections, whether in the junction box or to the Symmetra RM.
Verify that the battery modules have not been installed in the Symmetra RM. If
battery module(s) have been installed, remove them before installing any wiring.
Only an authorized electrician should install all power and control wiring, according to
national and local regulations.
Hard wire the input power on all 220/230/240 Vac (L1-N-G) units and on any 200/208
(L1-L2-G) unit with a load greater than 5 kVA.
Use flexible metal conduit to make maintenance and service easier.
