E-Bypass Control Features
Auto Bypass
•
Relay logic allows user to send the motor to bypass
mode based on the drive’s programmable relay.
•
The drive’s programmable relay, typically set to fault,
can be set up for applications that run full speed for
an extended period of time.
Enable Input
•
Generally used for safety tie-ins; the motor will not
operate the drive or bypass when open.
Common Remote Start/Stop
•
Common remote start/stop can be used in both drive
and bypass mode.
Essential Services Mode
•
Also used for smoke purge; the motor goes to bypass
regardless of the selected mode.
•
No call to stop will have an effect, including open
safety or stop commands.
•
Only turning the power off or opening this contact will
stop the motor.

NOTES:
1. Branch circuit protection to be provided by installer, per UL508A, if not provided with drive.
2. For bypass operation, modify these drive parameters: P0702[0] and P0702[1] = 3, P0748 = Digital Out 1 Reverse (
).
3. Control and communication wiring should be 300V UL minimum.
4. Communication wiring should be run with maximum separation possible from all other wiring.
5. Essential service mode operates the motor full speed (bypass) with no protection for the motor or system.
6. Ensure that automatic bypass will not damage the system before activating.
7. See Siemens Publication No. 125-3208 for proper fuse and wire sizes.
8. See Siemens Publication No. 125-3201 for SED2 input/output control signal wiring details.

SED2 Compliance with EN61000-3-12:
From September 1st, 2005 all electrical apparatus covered by the EMC directive will have to comply with EN610003-12 “Limits for harmonic currents produced by equipment connected to public low voltage systems with input
currents > 16A and =< 75 A per phase”.
Siemens variable speed drives of the product range SED2 (Micromaster 436) fulfill the requirements of the EN
61000-3-12 (without the need for external line reactors) regarding the THD values of Table 3 under the pre
condition of Rsce > 190. The required PWHD values will not be achieved. Due to this fact it is recommended to
apply for connection approval at the local electricity board.
The local electricity board will evaluate among many other data the content of the 5th harmonic current and the Line
Power Factor "Lambda”, which is the ratio of active power and apparent power.
Siemens frequency inverters are optimized in design and operation characteristics regarding energy efficiency and
less interference with line supplies.
