Energy Saving Unit (ESU)
When installed the ESU monitors the load of your installation and will switch on when
energy saving can be made. There is no sign of this change over and you will not be
affected by it.
The ESU monitors the incoming voltage so if you experience a phase voltage loss or
failure it reverts back to mains so your equipment isn't damaged.

How the ESU Operates
If you have an overload situation the unit will revert back to mains and reset once the load
has fallen to an acceptable level so as not to damage it.
There is an Ampere Meter on the front of the unit to indicate the load that is being used at
any time in save mode and mains mode.
