3.9.1.4 Enclosure Type
To provide a conductive and magnetic screen in addition to
safety segregation.
This minimises electrical radiated emissions from the drive
and helps protect the drive from radiating sources
Good environmental protection
plated or galvanised (e.g. Zintec)
For good electrical bonding
This gives good low inductance connections for electrical
bonding
Recommended
Rittal TS range:
• with galvanized frame and
• painted steel cladding
• without the rear mounting panel
or the EMV version for higher emission shielding.
3.9.1.5 Enclosure Further Requirements
Earthing / Bonding
The enclosure bonding must comply with instructions given in Section 3.5.3: Electrical Bonding.
Openings
Avoid all unnecessary apertures. All doors and covers to hazardous parts to be closed when the equipment is
energized.
Cable Glanding
The cables entering the enclosure must be correctly bonded through the gland plates. See Section 3.5.3:
Electrical Bonding.
