XII
CAUTION!
-
Please observe all applicable safety and accident prevention regulations! The rec-
ognized rules of electrical engineering must be observed!
-
Danger of injury or of damage to property due to inappropriate fastening! The place
of installation and the fastening method for the modules must be in compliance
with our specifications!
-
Danger of injury on sharp metal edges!
Please wear protective gloves.
-
Danger of damage to property through short-circuits!
When drilling or sawing out openings within switch cabinets, metal burr may get
inside modules that have already been installed. It is also possible that water may
emerge during the installation of the cooling water lines and may enter the modu-
les. The possibility of short-circuits and a destruction of the units cannot be entirely
ruled out.
Therefore, the modules should be well partitioned prior to any additional work! No
liability is accepted in the event of non-compliance.
-
Danger of life and of damage to property through insufficient protection type!
The protection type of the PSI 6101.321 / PST 6101.321 modules is IP 20. The
modules and the power unit form a single unit which must be installed simulta-
neously and incorporated in a housing or switch cabinet with a suitable degree of
protection.
-
Danger of injury and of damage to property through incorrect installation!
The weld timer, and especially the operating elements, must be installed so as to
be sufficiently protected against unintentional operation or contact.
-
Danger of injury and of damage to property when operating the units outside a
switch cabinet!
The units are designed to be installed in housings or switch cabinets and may only
be operated in such housings or cabinets with the door closed!
-
Danger of damages through static discharge!
Elements or components of the weld timer may be damaged by static discharge.
Do not touch any components or printed circuits with your hands. Installing and
configuring the system is reserved to qualified personnel.
NOTE
Connecting lines and signal lines must be laid so as to avoid negative effects on the func
tion of the units through capacitive or inductive interference and in compliance with the
requirements on electromagnetic compatibility (EMC), cf. also section 7 as well as gen-
eral information contained in the Bosch EMC manual for resistance welding components.
