- An installation guide,

If any problem is noticed upon reception, immediately contact the transport com-

pany and/or CIRCUTOR’s after-sales service.

2. PRODUCT DESCRIPTION

The DHC-96 CPM is designed to measure and display the DC voltage, DC current, power, energy and

electric charge.

Depending on the input current, Circutor has two models:

DHC-96 CPM, current measurement using shunt.

DHC-96 CPM-HS, current measurement using a Hall effect sensor.

The device features:

- 4 keys that allow you to browse between the various screens and program the device.

- LED display, displays all parameters.

- 2 fully programmable relay outputs

- 2 digital inputs.

- 1 programmable analog output, voltage or current.

- Communications RS-485.

CIRCUTOR has different models, see Table 3.

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, use the

necessary personal protective equipment, and pay attention to the various warnings

indicated in this instruction manual.

The DHC-96 CPM device must be installed by authorised and qualified staff.

The power supply plug must be disconnected and measuring systems switched off before handling, al-

tering 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 specific 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.

Instruction Manual

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.

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 fixing clips (Figure 2).

Clip de jación / Fixing clip

Figure 2: Fixing clips.

3.- Insert the device into the cut in the panel.

4.- Fit the fixing clips until the device is fixed to the panel.

The device should be connected to a power circuit protected by a fuse with a maximum nominal cur-

rent of 0.25 A.
