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, use the necessary personal protective equipment, and pay attention to the various warnings indicated in this instruction manual.

The DHC-96 Aac device must be installed by authorised and qualied staff.

The power supply plug must be disconnected and measuring systems switched off before

handling, altering the connections or replacing the device. It is dangerous to handle the device

while it is powered.

Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal

injury and damage to installations.

The device’s functionality is limited to the category of measuring voltage or specic current

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.

If an anomaly or malfunction is detected in the device, do not use it to take any measurements.

Disconnect the device from the power supply (device and measuring system power supply) before maintaining, repairing or handling the device's connections. Please contact the after-sales service if you suspect that there is an operational fault in the device.

3.2.- INSTALLATION

Terminals, opening covers or removing elements can expose parts that are hazardous 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.

To install it, take the following steps:

1�- Make a cut in the panel, according to the dimensions in Figure 1�

Figure 1: Cut in the panel�

2�- Remove the device’s xing clips (Figure 2).

Clip de jación / Fixing clip

Figure 2: Installation�

3�- Insert the device into the cut in the panel. 4�- Fit the xing clips until the device is xed to the panel.

The device should be connected to a power circuit protected by a fuse with a maximum nominal current of 0�25 A.
