Operation instructions
1.- Plug measure connections (2) and current connections (3) depending on
the measure that is going to be performed.
2.- Plug the mains connector (7) to the MPC and to the mains outlet. Device
is designed for AC 230V 50Hz/60Hz. Please ensure that the voltage is
correct before plugging the mains connector. In case of overvoltage, a
F250mA fuse will protect the device.
Note:
Plug the device to a line or generator able to supply the required power:
Power required > 600V x current to inject
Recommended power line circuit breaker I
n
should be, at least, 50A curve B, 30A curve C, or
16A curve D, as per EN60898. In case of using lower capacity circuit breakers, MPC won’t be
able to supply the maximun power.
Wiring cross-section and length may limit the maximun capacity of the MPC. Even when the
MPC, due to its current injection system, does not need high current capacity wiring and
connectors, we do recommend to use the bigger cross-section possible, in order to minimize
voltage losses that will affect the MPC maximun capacity. As an example, we show the
maximun earth resistance we can inject 5A, 10A, 25A and 50A, depending on the supply cord
used:

If using a rolled extension cord, it is mandatory to extend it completely before performing the
test. It is recommended to use the maximun cross-section possible, and the minimun cable
length.
