Mounting hardware

Method 1: The HF5 is supplied with 2 screws, 2 drywall anchors and two

rubber washers. The base of the enclosure has 2 screw-wells (see drawing)

that are normally closed at the bottom. Use the template provided with the HF5

to drill mounting holes in the wall and insert the drywall anchors. Place a

rubber washer on each screw. Insert a screw in each well and push to open

the bottom of the well.

Method 2: When a DIN-rail (35 mm / 1 3/8 “) is available use part AC5002 (not

included). This is a DIN-rail mounting kit consisting of 2 clamps that attach to

the back of the enclosure with the screws provided.

6 Electrical installation

6.1 General wiring guidelines

Power supply wiring

Heavy machinery and instrumentation should not share the same power supply wiring. If this cannot be

avoided, noise filters and surge protectors should be used. Most UPS devices have those features already

integrated.

General guidelines for signal cables

The following guidelines are derived from European Standard EN 50170 for the transmission of signals by

copper wires. When planning an installation, the rules provided by EN 50170 should be followed under

consideration of local circumstances to determine the position of machines and equipment.

All ROTRONIC products are tested for Electromagnetic Compatibility according to EMC Directive

2004/106/EG and following European standards:

- EN 61000-6-1: 2001, EN 61000-6-2: 2005

- EN 61000-6-3: 2005, EN 61000-6-4: 2001 + A11

Whenever the level of electromagnetic interference is expected to be high, both the instruments and signal

cables should be placed as far away as possible from the source of interference.

In general, signal cables should be installed in bundles or channels / conduits, separate from other cables as

indicated in the table below:

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 29 30
