4.13 Installation
The ME-MAX housing can be combined with a 5-pin TBUS connector / DIN rail connector. The RS485 interface
and the supply voltage can be easily wired through the TBUS connector that is snapped into the DIN rail. The TBUS
connection is self-establishing in the grid of the devices involved. This makes time-consuming pre-configuration or
reworking the TBUS connection on site obsolete.
Technical Data
:
5-pole connector in
3.81mm pitch
8A maximum contact load
Gold plating ensures high
contact quality.
Designed for mounting to
NS 35/7.5 or NS 35/15 DIN
rails
Important note:
The device may only be
attached to or removed
from the TBUS-Connection
when power is switched off!
Attach the housing to a 35
mm DIN-rail according to
EN 60715. For installation,
mount the snap-lock to the
DIN-rail and lock it. For
dismounting, use a screw-
driver to unlock the snap-
lock.
4.13 Electrostatic Discharge
Electrostatically sensitive assemblies can be destroyed by voltages that are far below the human perception limit.
These voltages occur when you touch a component or electrical connections of a module without being
electrostatically discharged. The damage that occurs to a module due to an overvoltage can usually not be
recognized immediately, but only becomes noticeable after a long period of operation. The device contains
components that can be damaged or destroyed by electrostatic discharge. When handling the device, observe
the necessary safety measures against electrostatic discharge (ESD) in accordance with EN 61340-5-1 and EN
61340-5-2.
