TW 3700 • TW 5550
2 .7 .5 GR OU NDI NG
The three waveform outputs (TRIGGER OUT, CLOCK & LOCK,
SYNC OUT) share the same ground. This ground should not exceed
20V Peak from chassis ground. If possible, this ground should be
connected to the chassis.
DFI, IEEE 488.2 and RS-232 share the same signal ground.
2 .8 I NP U T P OWE R R E QU I R E ME NT S
Input power is connected to the TW via the rear panel connectors. See Table 2-6 and
Table 2-7 for input current values. If it is required to shut the unit power off using the
front panel power switch, please wait at least 30 seconds before re-applying power.
WARNING! An overcurrent protection device (i.e., circuit breaker)
is required in the building installation. The circuit breaker should be
rated for continuous current as required by the TW system (see Table
2-2). Installation should comply with local safety standards.
A device to disconnect the TW system from the energy supply source
is also required. This switch or circuit breaker must be close to the
TW system, within easy reach of the operator, and clearly labeled as
the disconnection device for the TW system.
