Mounting the HMI on door
Follow this procedure to mount the HMI module,
separately on the door.
INFORMATION
It is important to use the cable which is
included in the package! To mount the HMI on a
door do the following steps:
1. Before mounting: Drill a 25 mm (1 inch) hole
through the door.
2. 1 Remove the HMI module from the Arc Monitor
by pressing on both sides on HMI and at the same
time,
3. 2 Pull straight out from the Arc Monitor.
4. 3 Add the sealing on the HMI.
• Mount the HMI on front door.
• Insert the back side of module into the door hole.
• Tighten the plastic nut by hand. Make sure the HMI is
fixed to the door.
5. 5 Connect the communication cable between the
HMI module back side and Arc Monitor right hand
side.
6. 6 Attach the label to cover HMI module hole on the
Arc Monitor front if needed.
Mounting the Optical detector
WARNING
Make sure that supply voltage is switched off!
This section is about optical detectors and the mounting
is described using examples:
• Where to positioning the detectors.
• How the detectors are mounted on busbars system.
This section also describes how to connect the detectors
to the Arc Monitor.
Decide where to position the detectors on the basis of
knowledge of your own system. The main issue is to cover
all components that might suffer from an arc.
INFORMATION
Excess plastic fibre cable should be wound up
and kept as a ring with a diameter of at least
100 mm (4 inches). The plastic fibre cables are
not to be bent in a loop with a radius of less
than 10 mm (0.4 inches) occasionally and 45
mm (1.8 inches) for a long period of time.
