5.5 Mechanical Installation
5.5.1 Mounting
Mount the connection box onto the backplate of the
control cabinet using M5 screws (not included). Only use
the designated keyways to mount the connection box. No
alterations to the back panel are allowed.
1.
Screw the holding screws in to the backplate so
that there is enough space to hook the
connection box onto them.
2.
Remove the protective cover from the connection
box.
3.
Hook the connection box onto the 2 holding
screws.
4.
Tighten the holding screws.
5.
Screw in the safety screws at the bottom of the
connection box and tighten them.
The optional strain relief clamps can be mounted to the
underside of the connection box by inserting them into
the cooling vents and securing them with an M4 screw.
5.5.2 Dismounting
1.
Unscrew and remove the safety screws at the
bottom of the connection box.
2.
Loosen the holding screws.
3.
Lift the connection box off the holding screws.
5.6 Electrical Installation
WARNING
GROUNDING HAZARD
For operator safety, it is important to ground the
connection box properly in accordance with national and
local electrical codes as well as instructions contained
within these operating instructions. Ground currents are
higher than 3.5 mA. Failure to ground the power supply
module properly could result in death or serious injury.
WARNING
HIGH VOLTAGE
The connection box contains high voltage when connected
to the power supply module. Installation, start up, and
maintenance should be performed by qualified personnel
only. Failure to perform installation, start up, and
maintenance by qualified personnel could result in death
or serious injury.
5.6.1 Earthing (Grounding) the Connection
Box
Connect the PE lines to the M6 earthing screw on the
underside of the unit.
5.6.2 Electrical Environmental Conditions
Compliance with the following electrical environmental
conditions is necessary to enable safe and effective
operation of the connection box:
•
Mounting in a control cabinet.
•
Suitable 24 V DC power supply unit (see
).
•
300 V DC with 10 A from the power supply
module.
•
PE line.
•
Pay attention to the leakage current. This is more
than 3.5 mA so a circuit breaker) is not effective.
Therefore use an AC/DC sensitive RCCB (residual
current circuit breaker).
•
Observe national statutory provisions.
5.6.3 24 V Power Supply Requirements
The connection box must be supplied with 24 V DC power
supply with the following properties:
•
Output range: 24 V DC
±
20%
•
Power output: 5 A
NOTE
Use a 24 V power supply which is CE marked according to
the standards EN 61000-6-2 and EN 61000-6-4 or similar for
industrial use. The power supply can only be used for the
ISD system.
