Most of the REx 5xx terminals can be rack, flush, semi-flush or wall mounted with the
use of different mounting kits. An additional box of type RHGS can be mounted to one
side of a 1/2 or 3/4 terminal. The 1/1 of 19-inches wide terminal can not be semi-flush
mounted due to that the mounting distance frame will cover the ventilating openings at
the top and bottom parts.
A suitable mounting kit must be available. Mounting kits contain all parts needed in-
cluding screws and assembly instructions. The following mounting kits are available:
• 19-inch rack mounting kits, 1/2, 3/4 and 1/1 terminal width variants. See section
2.1
"Mounting in a 19-inch rack".
• Side-by-side mounting kit. See section 2.2 "Mounting in a 19-inch rack with an ad-
ditional box type RHGS".
• Flush mounting kit. See section 2.3 "Mounting in a flush or semi-flush installation".
• Semi-flush mounting kit. See section 2.3 "Mounting in a flush or semi-flush instal-
lation".
• Wall mounting kit. See section 2.4 "Mounting on a wall".
