Step 2:
For the fastening of the SIPLUS PSU select under the following screws:
Screw type
Remark
Cylinder head screw M6 according to
ISO 1207/ISO 1580 (DIN 84/DIN 85)
Use screws of the strength category 8.8. Select
the screw length according to your construction.
Hexagon head screw M6 according to
ISO 4017 (DIN 4017)
For the assembly at coated and anodized cabinet bars use suitable bonding means, such as self
locking screws or special contact disks.
When changing the equipment, please notice chapter 8.5 “Replace of an Equipment”
Step 3:
For an optimal cable routing install the SIPLUS PSU in the undermost level.
Screw the mounting brackets together with the underground. Tighten the screws with a torque ac-
cording to chapter 5.1 “Mechanics” to get an electrical connection of low impedance between housing
and cabinet earth.
Step 4:
Put all channel switches into the “OFF” position. For not used supply outputs see chapter 7.4
“Inactivating of unused supply outputs”
Step 5:
Make sure that the feeding cables are de-energized.
Attach the cables for the cabinet feeding and for the transfer to the neighbor cabinet from below to
the SIPLUS PSU.
Step 6:
Standard cabinets are equipped with pre-assembled cable sets for the wiring.
Put the cables for the current sub-distribution into the plug connectors X1-X20 and those of the sig-
naling wiring into plug connector X21 (MELD / MELD_N). A wrong plugging of the lines is prevented
by reverse polarity protection.
Line plugs according to chapter 5.4 “Supply Outputs” and chapter 5.5 “Signaling Outputs” with high
current contacts (type HC) and increased withdrawal forces (type RDB) are used.
Note:
The plugs can be obtained as spare parts see chapter 9 “Order Designations”.
