Symmetra PX 10-80 kW 208 V Installation Sheet
Single Mains Installation
Remove labels on Bypass Input by pushing up the nylon tap. Remove
brackets on the L1, L2, L3 Mains Input and on L1, L2, L3 Bypass
Input. Save brackets for later conversion to dual mains if applicable.
Attach the 3 copper brackets L1, L2, and L3 (shipped in plastic bag in
the cable-land area of the UPS), using provided bolts and nuts.
Connect the cables to the AC mains input busbars, using provided
bolts and nuts.
Proceed with ground connections. Feed ground wire through provided
ferrite beads.
Route input and output wires in separate conduits: For output cables
L1, L2, L3 & N, use A and B conduits. For L1, L2, L3 & N mains
input, use conduits C and E.
Feed DC cables through the chase nipple in left side of the UPS and
into the Battery Enclosure.

EPO Switch Wiring
The UPS is to be connected to either a dry contact or a 24Vdc Emergency
Power Off (EPO) switch.
The EPO circuit is considered Class 2 and SELV (Safety Extra Low
Voltage). A SELV circuit is isolated from primary circuitry through an
isolating transformer and designed so that under normal conditions, the
voltage is limited to 42.4Vac peak or 60Vdc. SELV and Class 2 circuits
must be isolated from all primary circuitry. Do not connect any circuit to
the EPO terminal block unless it can be confirmed that the circuit is SELV
or Class 2.
For installations in US
– CL2Class 2 cable for general purpose use.
– CL2PPlenum cable for use in a vertical shaft or from floor to
floor.
– CL2R Racer cable for use in dwellings and raceways.
– CL2XLimited use cable for dwellings and raceways.
For installations in Canada
– CL2RCertified, type ELC (Extra-Low-Voltage Control Cable).
– CL2XCertified, type ELC (Extra-Low-Voltage Control Cable).

Warning
WARNING!
Ensure Total Power OFF before removing side panel (see
Total power OFF procedure).
