3. DEVICE INSTALLATION
3.1.- PRIOR RECOMMENDATIONS
In order to use the device safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used, using
the personal protective equipment necessary (rubber gloves, face protection and ap-
proved flame-resistant clothing) to prevent injuries due to electric shock or electric arc
as a consequence of exposure to current-carrying conductors and paying attention to
the various warnings indicated in this instruction manual.
The DCP-96 Aac device must be installed by authorised and qualified staff.
The power supply plug must be disconnected and measurement systems switched off before handling,
altering the connections or replacing the device. It is dangerous to handle the device while it is pow-
ered.
It is critical to keep wires in perfect condition to avoid accidents, personal injury or damage to instal-
lations.
Limit the operation of the device to measuring the specified current or voltage values.
The manufacturer of the device is not responsible for any damage resulting from failure by the user
or installer to heed the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of non-original products or accessories or those made by other manufacturers.
Do not use the device to take measurements if you detect an anomaly or malfunction.
Disconnect the device from the mains and from the power supply (both the device and
its measuring system) before performing any maintenance work, repairs or handling
any of the connections of the device.
Contact the after-sales service if you detect that the device is not working properly.

3.2.- INSTALLATION
Terminals, opening covers or removing elements can expose parts that are hazard-
ous to the touch while the device is powered. Do not use the device until it is fully
installed.
The device should be installed inside an electric panel or enclosure, and panel-mounted.
The following steps must be taken for correct installation:
1.- Make a cut in the panel, according to the dimensions in Figure 1.
91

Figure 1: Cut in the panel.
2.- From outside, insert the device into the panel cut-out (Figure 2).
Figure 2: Insert the device.
3.- Fully insert the device and fasten it by using the spring (Figure 3).
Figure 3: Fully insert the device.
The device must be connected to a power circuit protected by a fuse with a maximum nominal current

of 0.25 A.
If more than one device is connected to the current transformer, they must be connected in series.
Before disconnecting the current measurement connection cables, be sure to disconnect the trans-
former’s primary cables and bridge the secondary.
The device can operate in three-wire, three-phase mode or four-wire, three-phase mode, the user
selecting the corresponding connection mode according to the installation. An incorrect type of con-
nection or an error in phase sequence may cause measurement errors.
