The NEMA Type 3R/3RHE Bypass does not allow access to the drive display
during normal operation. For startup and programming of the drive, the enclosure
door must be open with power applied. This can be done by using the door anti-
lock defeatable mechanism (Figure 4) or by manually actuating the disconnect.
This should be done with extreme care, as high voltage will be present. Also, do
not stand directly in front of live parts when first applying power.
The SED2 is thoroughly tested at the factory. Verify that the drive is free of shipping
and installation damage. Shipping damage is not covered by the Siemens warranty;
claims must be filed directly with the shipping company as soon as possible.
Verify that the model numbers and the voltage ratings are as specified in the purchase
Verify that the 50/60 Hz DIP switch has been set to the appropriate setting, as
Inspect the security of the supply line power, ground connections, and all control circuit
Confirm that the incoming line power supply connects to the drive
input terminals (L1(r), L2(s), L3(t)) and NOT to the output motor
terminals (T1(u), T2(v), T3(w)).
Double check all power wires (L1(r), L2(s), L3(t)) and motor wires
(T1(u), T2(v), T3(w)) to make sure that they are securely tightened
down to their respective lugs. Loose wire connections may cause
problems at any time, and are not covered under warranty.
