Installation

Precautions

Safe Installation Install the system so that the ON/OFF switch is readily identiﬁable and is

easily reached by the operator. The ON/OFF switch or the detachable power

cord is the system disconnecting device. It disconnects the mains circuits

from the mains supply before other parts of the system. Alternatively, an

externally installed switch or circuit breaker (which is readily identiﬁable

and is easily reached by the operator) may be used as a disconnecting device.

Install the system according to the enclosure protection provided:

• The system protects against ﬁnger access to hazardous parts within the

enclosure.

• The system does not protect against the ingress of water.

CAUTION This product is designed for use in Installation Category II and Pollution

Degree 2 per IEC 1010 and 664 respectively.

CAUTION Always use the three-prong ac power cord supplied with this product.

Failure to insure adequate earth grounding by not using this cord may cause

product damage.

CAUTION Before switching on the system, make sure that the correct fuse is installed,

and that the supply voltage is in the speciﬁed range.

CAUTION Ventilation requirements:

Convection in and out of the system cabinet must not be restricted. The

ambient temperature (outside the cabinet) must be less than the maximum

operating temperature of the system by 4°C for every 100 watts dissipated in

the cabinet. If the total power dissipated in the cabinet is greater than 800

watts, then forced convection must be used.

WARNING This is a Safety Class 1 Product (provided with a protective earthing ground

incorporated in the power cord). The mains plug shall only be inserted in a

socket outlet provided with a protective earth contact. Any interruption of the

protective conductor inside or outside the product is likely to make the

product dangerous. Intentional interruption is prohibited.
