While running in Emergency Bypass Mode, the operating voltage is still measured accurately and is the most
reliable parameter. It is advisable to monitor the voltage to ensure that the Energy Pak is operating in the
appropriate voltage range:

●

12.0 - 14.0 V for 12V models

●

24.0 - 28.0 V for 24V models

●

48.0 - 56.0 V for 48V models

After the emergency use, turn the Emergency Bypass Switch to the OFF pos

ition and have your Energy Pak

inspected by your authorized service agent.
