detector or separator does not exceed the limits stated in the provisions. Therefore there
are no health impairments due to electromagnetic fields in this area for persons and for
wearers of medical implants such as cardiac pacemakers. Inside the coil of round or
closed tunnel coils, or on the surface of flat coils, the limits may be exceeded depending
on design and system version. If work is to be performed inside or at the search coil, per-
sons and wearers of medical implants such as cardiac pacemakers may only enter the
equipment when it is turned off, provided that size and design allow this.
4.5 Safety information for operation, maintenance and cleaning
Because of energised components in the electronics housing there is a risk of injuries due
to electric shock or burns. During operation the cover of the electronics housing must be
kept closed. Only qualified personnel may operate and clean the equipment.
If the electronics housing must be opened for maintenance or cleaning purposes, remove
any dirt and moisture from the electronics housing, so that no larger amounts may get into
the interior. Always disconnect the power supply and any connected external circuits be-
fore opening the cover. Any moisture that has penetrated into the interior must be re-
moved from the electronics housing. If any maintenance work must be performed in
energised condition, e.g. battery replacement, such work may only be performed by a
qualified electrician under strict observation of the attached warning labels and with due
regard to standard approved rules of electrical engineering.
No safe condition is established when outputs are switched "inactive" (with "Disable Out-
puts", "Bypass", or "Output level inactive".
For any maintenance work the compressed-air and power supply of the machine must al-
ways be disconnected, and any existing pneumatic cylinders must be vented.
4.6 Safety information for commissioning
To avoid any injuries due to energised parts in the electronics housing, the information in
5.1 and 5.2 must always be observed.
4.7 Safety information for storage and transport
Always observe the information in paragraph 10 to avoid any transport damage and per-
sonal injuries.
4.8 Notes on residual risks
Electrical circuits may still be live even after having been isolated from the mains. Switch
off immediately if a fault occurs.
4.9 Notes on stable standing requirements
To avoid any loss of stable standing, the information for transport, commissioning and op-
eration must always be observed. Always make sure that the fastening screws of the con-
trol unit are tight during operation. When storing or transporting the control unit, place it on
the closed rear panel of the housing.
4.10 Consequences of unauthorised modification
Unauthorised modification or repair will invalidate all manufacturer declarations and guar-
antees.
