System Electrical Information

6Symmetra® PX 10-80 kW 208 V Site Preparation Guide - 990-1425A

This UPS system has no built-in disconnection devices for AC output and DC input. An AC output

over-current protection and AC output disconnect must be provided by the customer. For customer-

supplied external batteries, over-current protection and a disconnecting device for the battery circuits

must also be provided by the customer.

EPO switch wiring (required)

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.

Use one of following cables to connect the UPS to the EPO switch:

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).
