Section III
Operation
Set-Up
The recommended procedure for setting up the MPS or MPPS is the following:
• Make sure the AC BREAKER on the rear panel of the MPS or MPPS is in the OFF position.
• The AC breaker on the rear panel is classified as a supplementary protector and is not
designed for branch circuit protection. A suitable circuit breaker should be added externally
for the AC input if branch circuit protection is required.
• Connect the ground wire to the ground stud on the rear panel of the MPS or MPPS.
• Connect the DC OUTPUT cables, first to the MPS or MPPS and then to the load with the
correct polarity.
• Connect the USER I/O cables.
• Connect the INPUT cables, first to the MPS or MPPS and then to the AC source.
• Turn on the source (if they have an up stream breaker).
• Move the AC BREAKER on the rear panel of the MPS or MPPS to the ON position.
Start-Up
• VERIFY that all connections to the MPS or MPPS are correct.
• If the AC source is present and within specifications, the three POWER IN LEDs on the front
panel will be green.
• Momentarily push the ON/OFF switch on the front panel of the MPS or MPPS upward. The
switch can then be released and it will return to its normal (neutral) position.
Shut-Down
• Shut down the equipment connected to the MPS or MPPS.
• Push the ON/OFF switch on the front panel of the MPS or MPPS downward and hold it
in this position for 1 second (or more). The switch can then be released to return to its
normal position.
• The MPS or MPPS will disable its outputs.
• It is not necessary to move the AC BREAKER on the rear panel of the MPS or MPPS to the
OFF position.
