withstand currents of up to 150 A for 20 ms without affecting their strength or
features.

6.- UNIT INSTALLATION
This manual contains information and warnings that the user must adhere to in order to guarantee
the safe operation of the reconnecting device, maintaining it in a good state with regards to safety.
The unit should not be switched on until it has been mounted in its final location in the electric
cabinet.
If the unit is used in a manner other than that specified by the manufacturer, its
protection elements may be compromised.
When it is likely that the unit has lost its safety protection (signs of visible damage), it should be
disconnected from the auxiliary power supply. In this case, contact a qualified technical service
representative.
6.1.- INSTALLATION
The Getest may be powered directly from the mains (230 Vac and 50-60 Hz) or from a single-
phase generator set. The required power of the generator set will depend on the value of the circuit
loop resistance. This means that the bigger the loop resistance (test earthing plus auxiliary
earthing), the more power the generator set must have in order to inject the current required by the
user.
The line protection circuit breaker device must be, at least, 50 A for B-curve circuit breakers, 30 A
for C-curves and 16 A for D-curves, according to the EN60898 standard. If using devices with
lower capacity, the MPC will not be able to deliver the maximum power.
The cross-section and length of the connection cable may limit the MPC's capacity. Despite the
MPC not needing high-capacity cabling or connectors due to its current injection system, we
recommend that the cross-section of the power supply cables be as large as possible, to reduce
voltage losses that affect the device's maximum capacity. As an example, indicated below is the
maximum earth resistance to which 5, 10, 25 and 50 A may be injected, depending on the power
supply cable used:
