Instructions for Assembly and Operation
ATTENTION!
-- 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 injury and of damage to property through missing or false interpreta-
tion of fault messages!
Therefore, closing of the temperature contact connected to X5 of PSU must in-
hibit the connected timer (cf. also Section 11, "Electrical connection")!
For interpreting the fault messages also note the information contained in Sec-
tion 7, "Monitoring and diagnostics".
-- Danger of bruises through electrode movement!
All users, line designers, welding machine manufacturers and welding gun pro-
ducers are obliged to connect the output signal of the Bosch weld timer which
initiates the electrode movement so that the applicable safety regulations are
complied with.
The risk of bruises can be considerably reduced by means of,
e.g., ` two--handed start
` guard rails
` light barriers etc.
NOTE
-- Damage to property through inappropriate or insufficient cooling of the modu-
les!
Water--cooled PSU and PSG modules may only be operated when the cooling
water circuit is active! Condensation is not permitted on water--carrying compo-
nents. The temperature in the installation room of air--cooled modules must be
within the specified limits.
-- Damage to property through excessive welding current!
The maximum welding current of the combination of PSG and PSU in use must
not be exceeded. No liability is accepted in the event of non--compliance.
The max. admissible welding current of each combination of units is to be deter-
mined from the load diagrams (cf. Section 5.3)!
The MF welding inverter has been designed and manufactured by us as a safe unit.
WARNING!
Retrofits or modifications may have negative effects on the safety of the unit!
!
Therefore, please contact us prior to retrofits or modifications to the MF welding
inverter using third--party equipment. This is the only way to determine whether
these parts are suitable for use with our product.
