Installation and Operation Manual

Site Requirements and Prerequisites
2.2 Site Requirements and Prerequisites
Input Power Requirements
For AC operation, the MX-2100 unit should be installed within
1.5m (5 feet) of an easily-accessible grounded AC outlet capable of furnishing the
mains voltage of the ordered KPS module. KPS.4 and KPS.6 modules of MX-2100
and the AC power supply of MX-2104 can operate on AC supply voltages in the
range of 100 to 240 VAC, at input frequencies of 47 through 440 Hz. The
maximum input current varies with the input voltage.
For DC operation, the MX-2100 unit should be connected to a -48 VDC or
-24 VDC source (in accordance with the nominal voltage of the ordered KPS
module) through a circuit breaker. The DC source must comply with the
requirements of EN60950.
Grounding
For your protection and to prevent possible damage to equipment when a fault
condition, e.g., lightning stroke or contact with high-voltage power lines,
occurs on the lines connected to the equipment, the case of the MX-2100 unit
must be properly grounded at any time. Any interruption of the protective
(grounding) connection inside or outside the equipment, or the disconnection
of the protective ground terminal can make this equipment dangerous.
Intentional interruption is prohibited.
Before switching on this equipment and before connecting any cables, the
protective ground terminals of the equipment must be connected to a protective
ground. The grounding arrangements depend on the equipment power supply
source:
•
AC-powered units: the grounding connection is made through the mains plug,
which must be inserted in a power socket (outlet) with protective ground
contact. Do not negate the protective ground contact by using an extension
cord (power cable) without a protective conductor (grounding).
•
DC-powered units: the grounding connection is made through one of the pins
of the DC power connector.
•
In addition, all units/PS modules have a grounding terminal: connect it to the
nearest grounding point using a short, wide copper braid (or a thick copper
wire).
Whenever possible, the MX-2100 units should be installed in a properly grounded
rack, connected to a reliable, low-resistance grounding system.
