SHM-768K
WARNING
Before connecting AC power to this unit, the protective earth terminals of
this unit must be connected to the protective ground connector of the
(mains) power cord. The mains plug should only be inserted in a socket
outlet provided with a protective earth contact. The protective action
must not be negated by use of an extension cord (power cable) without a
protective conductor (grounding).
The fuse is located in a bayonet-type fuse holder located on the rear
panel. Make sure that only fuses of the required rating, as marked on the
rear panel, are used for replacement. Do not use repaired fuses or short-
circuit the fuse holder. Always disconnect the mains cable before
removing or replacing the fuse.
WARNING
Whenever it is likely that the fuse protection has been damaged, make
the unit inoperative and secure it against unintended operation.
Grounding: Interrupting the protective (grounding) conductor (inside or
outside the unit), or disconnecting the protective earth terminal can
make this unit dangerous.
6.4 Installation
After installing the RM110A in the 19" rack:
• Insert SHM-768K cards.
• Tighten the nut on the top of each card.
• Push the bottom of the cards further into the rack to ensure they are fully
inserted into the edge connectors.
Do not use excessive force. If the card does not go in easily, remove the
card, realign it with the enclosure guides, and push it in place.
6.5 Operation
The power supply is controlled from the power module on the right hand
side of the RM110A (Figure 6-1). The ON/OFF switch controls the power
supply to all the cards.
