General Installation Requirements
This product is intended for use with the Product Sub Family system. Its components are considered open
equipment (having live electrical parts that may be accessible to users) and must be installed in an ultimate
enclosure that is manufactured to provide safety. As a minimum, the enclosure shall provide a degree of
protection against solid objects up to 12mm (e.g. fingers). This equates to a NEMA/UL Type 1 enclosure or an
IP20 rating (IEC60529) providing at least a pollution degree 2 environment.
Installation in Hazardous Areas
The following information is for products bearing the UL marking for Hazardous Locations or ATEX marking for
explosive atmospheres:
▪ EQUIPMENT LABELED WITH REFERENCE TO CLASS I, GROUPS A, B, C & D, DIV. 2 HAZARDOUS LOCATIONS IS
SUITABLE FOR USE IN CLASS I, DIVISION 2. GROUPS A, B, C, D OR NON-HAZARDOUS LOCATIONS ONLY
▪ Equipment labeled with II 3 G is suitable for use in Group 2 Category 3 environments.
▪ WARNING - EXPLOSION HAZARD - SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I,
DIVISION 2;
▪ WARNING - EXPLOSION HAZARD - WHEN IN HAZARDOUS LOCATIONS, TURN OFF POWER BEFORE REPLACING
OR WIRING MODULES; AND
▪ WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED
OFF OR THE AREA IS KNOWN TO BE NONHAZARDOUS.
▪ WARNING - EXPLOSION HAZARD - USB PORT IS ONLY FOR USE IN NONHAZARDOUS LOCATIONS, DO NOT

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.
