Installing The Pcs Onsite - Delta PCS100 Installation Manual

Installing the PCS Onsite

The PCS Series must be located in weather-proof enclosure or enclosed-area. The PCS is not
intended or designed for exposure to water or excessive dust.
The PCS system is designed to support the requirements of various environments.
 The PCS must be in an upright position at all times.

The PCS functions at optimal operating performance if installed in a temperature range of -20° C
to 25° C (32° F to 77° F).
The specifications are available in "Specifications" on page 68.

Safety Considerations
The following safety information is intended to reduce the risk of accidents:
 Keep the floor around the PCS clean to prevent metallic dust, iron or other metal filings from
being drawn inside the device, consequently causing short circuits.
Closed area installations:
 The floors and surrounding area around the PCS must use non flammable material.
 A portable powder fire extinguisher must be installed within easy reach of the PCS.
 An automatic fire extinguishing system should be installed and enabled for the site.
 Access to the installation site should be restricted to qualified service personnel.
Surge Arrester Safety
The function of lightning and surge protection systems is to protect the devices, functional isolations
and over voltage-sensitive consumer equipment of the PCS. The PCS is equipped with a Class II SPD
to cover the system when not placed in a directly lightning strike area.
Due to the wide surge energy, voltage and frequency range of over voltage in lightning strike areas, it
is recommended:
1. Where the system is equipped with an external lightning protection system(LPS) or protection
against effects of direct lightning is otherwise specified, Class I SPDs shall be used.
2. Where the system is not equipped with an external lightning protection system(LPS) and
where the occurrence of direct lightning strike to the overhead lines between the last pole and the
entrance of the installation is to be taken into consideration, Class I SPDs at or near the origin of the
electrical installation shall be used.
3. Class II SPDs shall at least be installed as close as possible to the origin of the installation in
the system, for example in the upstream distribution board for PCS.
Battery Ground Fault Concerns
The following are concerns surrounding potential risks of DC ground faults and the possible causes.
WARNING!
!
To prevent possible escalation into serious or catastrophic ground faults, make sure to equip
the corresponding Ground Fault Detection (GFD) equipment and follow strict maintenance
guidelines.
The primary concerns with any Battery Ground Fault include three principle areas:
1. Fire due to ground fault.
2. Risk to personnel due to ground or battery fault.
