The user should carefully review the following information:
Safety and Compliance
Electrical Safety and Compliance
This equipment is rated for operation over the range of 90 to 264 Volts AC (VAC), or 38 to 60
Volts DC (VDC). It has a maximum power consumption of <90 Watts. The unit complies with the
EN 60950 Safety of Information Technology Equipment (Including Electrical Business
Machines) safety standard.
If the unit is operated in a vehicle or movable installation, make sure the unit is
stable. Otherwise, EN 60950 safety is not guaranteed.
Electrical Installation
Connect the unit to a power system that has separate ground, line and neutral
conductors. Do not connect the unit without a direct connection to ground.
Fuses
For continued operator safety, always replace fuses with the correct type and rating.
The AC-powered CRS-500 1:N Redundancy System’s Control Switch Unit (CSU) is fitted with two
fuses – one is for line connections, one is a spare. They are contained within the body of the IEC
power inlet connector, inside a press-fit fuse holder. Note the following:
• For 230 Volts AC operation, use T2.5A 20mm fuses. (P/N TBD)
• For 115 Volt AC operation, use T2.0A slow-blow fuses (P/N 5ASB-IEC).
The DC-powered CSU is fitted with two fuses – one each for positive and negative connections.
They are contained within the body of the power inlet connector, inside a press-fit fuse holder.
Note the following:
• For 38 to 60 Volt DC operation, use T2.0A mm fuses.
