Electrical Installation
CAUTION: Risk of electric shock. Disconnect the SDU from the electric supply before proceeding
with the connection.
The wiring to the SDU must be done by a qualified electrician and must conform to the procedure, regulation
and local codes.
Use copper conductors only.
An external over current protection must be installed on the supply, adjacent to the SDU. It is also
recommended to install a circuit breaker.
To provide strain relief to the supply cable, install a knock-out (not supplied) at the bottom of the SDU.
Ensure that the size of the wire conductors is appropriate for the current supplied.
Ensure that each terminal connection is properly secured.
Ensure that the ground conductor is equipped with a ring terminal and is connected directly to the electrical
panel.
