be provided by an MPC4 / IOC4T card pair.

NOTE: Refer to the individual data sheets for full technical specifications of the MPS

hardware.

Finally, a combined machinery protection and condition monitoring system can integrate the

following condition monitoring hardware in the VM600 rack (ABE04x):

• XMx16/XIO16T extended monitoring card pairs.

NOTE: Further information on the condition monitoring system hardware can be found in

the VM600 condition monitoring system (CMS) hardware manual.

Figure 1-2 and Figure 1-3 show front and rear views of a typical VM600 rack (ABE04x)

containing machinery protection system (MPS) hardware.

NOTE: Refer to the data sheets for full technical specifications of the VM600 MPS

hardware (rack, cards and modules).

1.3.1 Ventilation

VM600 racks do not contain any ventilation units (fans). They therefore rely on either forced

ventilation by fans in the cabinet or on natural ventilation (convection) for their cooling. All

require the free flow of air in an upward direction, with air entering the rack through the vents

in the base of the rack and leaving it through the vents on the top of the rack.

When racks are installed in a cabinet or enclosure, in which natural ventilation is used, a

space of at least 50 mm should be present below and above each rack for an ABE04x rack

(see Figure 1-6, Case A).

It is possible to prevent warm air flowing from one rack to another, by placing inclined plates

between them in order to deflect the airflow (see Figure 1-6, Case B). When inclined plates

are used with VM600 racks, an inclined plate can also function as a non-flammable

separation barrier, if required (see 1.3.4 Instructions for locating and mounting). In addition,

the space of 50 mm should be present below and above ABE04x.

If an ABE04x rack is assembled without empty slots between the MPS and/or CMS

processing cards, it is recommended to use forced ventilation if the temperature of the air

flowing through the rack exceeds 40°C. If a 19” x 6U rack has at least one empty slot between

each processing card, it is recommended to use forced ventilation if the temperature of the

air flowing through the rack exceeds 55°C.

In a case where forced ventilation by fan units is used, the spacing above, below and between

racks can be reduced to zero, providing that the airflow to/from neighbouring racks is

ensured.

Always ensure adequate spacing (minimum 50 mm for ABE04x racks) is

provided below and above the rack to allow proper natural ventilation.

Failure to adhere to this requirement will cause overheating of the rack and

as a consequence will affect the correct operation of the system.

HAZARDOUS TEMPERATURES CAN EXIST WITHIN AND ON VM600 SYSTEM

RACKS (ABE04X).

DEPENDING ON THE AMBIENT OPERATING TEMPERATURE, NUMBER OF CARDS AND

POWER SUPPLIES INSTALLED (AND THEIR CONFIGURATION AND OPERATION), THE

INSTALLATION AND COOLING (FORCED OR NATURAL VENTILATION), THE TOP OF A

VM600 RACK CAN BECOME HOT AND THERE IS THE RISK OF BURNING WHEN HANDLING

THE RACK.

SEE ALSO HOT SURFACES AND THE RISK OF BURNING ON PAGE XVII. 

1.3.2 Circuit breaker

In some circumstances the operator must ensure a switch or circuit breaker is provided in

order to comply with the IEC/EN 61010-1 standard. This standard stipulates that permanently

connected equipment (such as a VM600 ABE04x rack) must employ a switch or circuit

breaker as a means of disconnection from the mains supply.

A VM600 rack using the AC-input version of the RPS6U rack power supply already have an

ON/OFF switch or switches (and a fuse or fuses) at the rear of the rack. However, this is not

the case for the DC-input versions of the RPS6U rack power supply, so an appropriately rated

external circuit breaker or equivalent must be used.

1.3.3 Supply wiring

A VM600 rack using the AC-input version of the RPS6U rack power supply is supplied with a

mains power supply lead (power cord). Power supply rear panels with two AC inputs for

independent mains supplies are supplied with two mains cables. However, no lead (cable) is

supplied with a VM600 rack using the DC-input version of the RPS6U.

NOTE: Refer to the VM600 RPS6U rack power supply data sheet and VM600 system rack

(ABE04x) data sheet for further information on the mains power supply lead (power

cord) supplied with a VM600 rack.

For a VM600 rack using a DC-input version of the RPS6U rack power

supply, the mains power supply lead (power cord) linking the VM600 rack

to the mains supply must pass through an external switch or circuit

breaker.

The switch or circuit breaker must be installed and used in accordance with

the manufacturer’s instructions in order to ensure the correct and reliable

protection of the VM600 rack.

The switch or circuit breaker must be chosen in accordance with the

version of the DC-input RPS6U rack power supply used, and in particular

the maximum permitted input current and output power.

The operator must have easy access to the switch or circuit breaker at all

times.

For further information, refer to the VM600 machinery protection system

(MPS) hardware manual.

In general, for a VM600 rack, the mains power supply lead (power cord)

used must be of sufficient cross-section to meet the power requirements of
