Power Supply Information
ATTENTION
:
This case must be earth grounded. No DC input may be earth
grounded. Use Isolated Power Supply
Power Connection Warning
: Connect the power supply to the switch first, and then
connect the power supply to power. Otherwise, catastrophic product failure may
occur.
1.
Verify that power is off to the DC circuit that you are going to attach to the
switch DC-input connector. This can be either of the two power supplies (AC-input
or DC-input) or site source DC.
2.
As an added precaution, place an appropriate
safety flag and lockout device at the source power circuit breaker, or place a piece of adhesive tape over the
circuit breaker handle to prevent accidental power restoration while you are working on the circuit.
Power Disconnection
: To disconnect power from the switch after a successfully boot, follow these steps:
1.
Turn
off power to the switch.
2.
Disconnect the cables.
Warning
: Only wire with insulation should extend from the connector. An exposed wire lead from a DC-input
power source can conduct harmful levels of electricity. Be sure that no exposed portion of the DC-input power
source wire extends from the connector(s) or terminal block(s).
Power Supply Warnings & Cautions !!
1.
Risk of electrical shock and energy hazard. All failure should be examined by a qualified technician. Please do
not remove the case of the power supply by yourself!
2.
Risk of electric arcs and electric shock (danger to life). Connecting both the primary and the secondary sides
together is not allowed.
3.
Risk of burn hazard. Do not touch the unit in operation and shortly after disconnection!
4.
Risk of fire and short circuit. The openings should be protected from foreign objects or dripping liquids.
5.
Only install the unit in a pollution degree 2 environment (where there is only non-conductive pollution that
might temporarily become conductive due to occasional condensation. Generally refer to dry, well-ventilated
locations, such as control cabinets).
6.
Please do not install the unit in places with high moisture or near the water.
7.
The maximum operating temperature is 60°C. Please do not install the unit in places with high ambient
temperature or near fire source.
8.
The FG (
) must be connected to PE (Protective Earth).
9.
Output current and output wattage must not exceed the rated value on its specification.
10.
Disconnect system from supply voltage: Before commencing any installation, maintenance or modification
work: Disconnect your system from supply voltage. Make sure that inadvertent connection in circuit will be
impossible!
11.
For continued protection against risk of fire, replace only with same type and rating of fuse.
Pour ne pas compromettre la protection contre les risqué d’incendie, remplacer par un fusible de même type
et de memes caractéristiques nominales.
