2 Installation
2.1 Installation Notes
The following guidance must be followed for proper installation of the product.
1. Mounting: This product is designed for mounting in an EIA-310 compliant 19” rack. The user is responsible for
ensuring the mounting method provides adequate structural support for the product, and any attached cables.
The user is also responsible for ensuring the mounting location provides adequate ventilation to dissipate heat
generated during operation of the product. Ensure the product is securely mounted before applying power.
2. Chassis ground: The rear of the chassis includes a redundant chassis ground screw and ground wire. If desired for
your installation location, connect the chassis ground wire to the rack cabinet using an appropriate fastener.
3. Optionally, connect the appropriate cables between the PDU outlets and the equipment being powered by the PDU.
This may be done later according to the startup procedures suitable to the end-user’s equipment and application.
4. If applicable, connect the cabling between the PDU and remote EPO control panel.
5. PDU Main Breaker: Ensure the Main Breaker on the front of the PDU is in the off position before connecting the
PDU’s inlet cable to the facility power source. (It is best to switch all breakers to the off position.)
6. Facility Power Source: The single-phase facility power source for this product must include an overcurrent protective
device capacity as defined in the table below:

Some Optima 520 units can be heavy. The flange mounting ears are designed to hold the PDU
securely against the rack mounting rails, but are NOT designed to support the weight of the PDU
vertically. The end user is responsible for ensuring the PDU’s weight is properly supported by the
rack’s infrastructure (which may involve adding support rails).
