Power up procedure

Standard HP POD 20c power up procedure

This procedure is for your reference only and assumes that the POD is fully commissioned and powered up

by HP before being turned over to you.

Before beginning the power up procedures in this section, verify that the POD is not in operation and that the

internal ambient temperature of the POD is greater than 10ºC (50ºF). If the internal ambient temperature of

the POD is less than 10ºC (50ºF), see "Cold weather HP POD 20c power up procedure (on page 70)."

This process helps to ensure personnel safety during the electrical start up of the HP POD 20c.

WARNING: To avoid risk of personal injury or loss of life, do not open an energized POD

electrical cabinet without an energized work permit and appropriate PPE.
