PS4100 Installation Guide Rack Mounting the Array

• Load a rack with arrays from the bottom to the top.

• There must be at least 4.1 cm (1.6 inches) between the rack door and the front of the array to

accommodate the array front bezel.

• The rack (with installed arrays) must meet the safety requirements of UL 60950-1 and IEC 60950-1.

• Mount the array in a horizontal orientation, or you will void your array warranty and support contract.

Environmental Requirements

The rack location must meet the following environmental requirements:

• Only operate an array from a power source with a voltage range of 100 to 240 VAC.

• Make sure each power source has sufficient electrical overload protection.

• In North America, connect the array to a source of power with over-current protection provided by a

double pole 20A or less device (UL 489 circuit breakers). In Europe, the over-current protection must

be provided by a 20A or less device (IEC circuit breakers).

• Make sure there is sufficient space for air flow in front of and behind the array.

• Make sure the location is properly vented.

• Review the technical specifications in Technical Specifications on page 35 to make sure your

environment supports its requirements.

Protecting Hardware

Protect a PS Series array from electrostatic discharge. When handling array hardware, make sure you use

an electrostatic wrist strap or a similar form of protection.

To use a wrist strap:

1. Connect the steel snap on the coil cord to the stud on the elastic band. See Figure 1.

Figure 1 Using an Electrostatic Wrist Strap

2. Fit the band closely around your wrist.

3. Connect the banana plug to ground, or attach the plug to the alligator clip and connect the clip to a

grounded device such as an ESD mat or the metal frame of a grounded piece of equipment.
