14.3 Hints on how to avoid electrostatic discharge (ESD)
When connecting the OCM F the following warnings and hints shall be observed right as the
warnings and hints found in the according chapters on installation.
WARNING
Disconnect the unit from mains power
Disconnect the instrument from mains power before you begin to carry out maintenance,
cleaning and/or repair works (expert personnel only).
Disregarding may lead to electric shocks.
The sensitive electronic components inside of the instrument may be damaged by static
electricity which may impair the instrument’s performance or even lead to instrument failure.
The manufacturer recommends the following steps to avoid equipment damage due to elec-
trostatic discharge:
•
Discharge static electricity from your body before touching the instrument’s electronic
components such as circuit boards and the components installed on the boards. To do
so touch a grounded metal surface such as the unit’s enclosure frame or a metal pipe.
•
Avoid unnecessary movements to reduce the risk of building up static electricity.
•
Transport statically sensitive components in antistatic containers or packing materials.
•
To discharge your body and to stay free of static electricity wear an antistatic wristband
grounded through a cable.
•
Only touch components that are sensitive to electric charges in an antistatic working
area. If possible, use antistatic mats and work pads.
14.4 Transmitter Installation
Front panel
It is not allowed to remove the front panel.
Tightness of the terminal housing
Water or dirt must not leak into the terminal housing. Seal the housing with the supplied lid
and both screws respectively.
Mounting Wall Mount Enclosure
Ensure proper installation.
The most simple way to install a wall mount enclosure is to fasten a DIN rail with a length of
210 mm (8.3 in.) and then to snap-on the enclosure.
It is possible to install the enclosure by using three screws as well. Use a pan head screw
with a head diameter of 5.5...8.0 mm (0.22...0.32 in.) for this. This screw must be screwed in-
to the mounting plate protruding 4 mm (0.16 in.). Then hang the enclosure on the screw and
additionally fix it with two more screws from the terminal clamp housing. Make sure to screw
them not less than 40 m into the wall or 50 mm into appropriate dowels which need to be set
previously.
General
The field enclosure has cable glands and dummy plugs. Some of them are screwed in and
some are enclosed as spare parts or additional parts.
The transmitter contains:
•
1x gland M16x1.5 with counter nut
•
2x gland M20x1.5 with counter nut
