The Eaton 93PM-L UPS complies with ANSI 62.41 for line surges. However, if added security is required an
additional Surge Protection Device (SPD) can be installed. For this application, a 208V Delta Style SPD Type 1 or
Type 2 installed on the load side is recommended. The SPD must meet the Maximum Continuous Operating
Voltage (MCOV) for a 208V Delta Style SPD. Eaton offers a variety of SPD solutions including the Eaton SPD
Series with various kA ratings options.

The 93PM-L (60 kW) UPS battery system can be internal to the UPS cabinet, an external Integrated Battery
Cabinet/s (IBC), or a combination of both. The external IBCs are connected in parallel with the internal batteries
to provide extended run time. The battery system is equipped with sealed lead-acid, maintenance-free
batteries.
An external battery disconnect switch or tie point must be used when battery systems are located separate
from the UPS cabinet and wiring exceeds the number of battery terminals available.
A supplemental 48 Vdc shunt trip signal for the battery disconnect device is provided by the UPS, but is not
required for normal operation.

Thermal runaway protection for VRLA batteries can be provided by adding an optional thermal sensor to the
internal battery section or external battery cabinet.
The sensor is wired to the thermal sensor terminal and programmed to turn the charger off when a trip signal is
received.
The thermal sensor will maintain the trip state until it is reset by service. Service should be called to inspect the
batteries and reset the sensor in case of such an event.
