Module Installation

Modules must be mounted on a DIN rail.

1. Allow sufficient finger clearance for opening PNS door.

2. Allow adequate clearance for communications port cables.

3. Allow adequate space for power wiring.

The PNS with power supply attached fits into a 70mm deep enclosure.

Rated thermal specifications are based on a minimum clearance of 5.1cm

(2in) above and below the equipment and 2.54cm (1in) to the left of the

PNS module.

You may need to allow more space for installation of cables and

connectors than what is required for heat dissipation. To avoid impacting

mechanical reliability and signal quality, cable installation must comply

with the minimum bend radius specified by the cable manufacturer.

Grounding

The VersaMax PROFINET Scanner must have a separate shield ground connection to provide shielding for its two ports.

Attach a wire with a stab-on connector to the grounding terminal on the bottom of the module. Connect a ring terminal on

the other end of the wire to a grounded enclosure. Where the ring terminal contacts a painted enclosure panel, either install

a star lock washer between the terminal and the panel to cut through the paint, or scrape the paint away down to clean,

bare metal to ensure a good contact. Note: The star lock washer method is suitable for a shield ground, but not suitable for

a safety ground.
