The power supply, where the supply cable is connected, must be positioned near the equipment and be
on an easily accessible location, because the equipment is turned on and off through it .
In case of using DC voltage, you must be careful so that the equipment protection earth cable (green
cable with yellow line related to the central socke
t pin) matches the system protection earth cable. This
cable must be connected before any other connection.
The equipment supports an 1
A fuse, type T (delay), 250 V. If necessary, replace it only for another one of
the same type and value.
To prevent risks of electric shock, before opening the DM991C/CE equipments, disconnect the
power
supply.
