PISA11

PISA11-Series

This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do

not cover ventilation grid.

The standard mounting orientation is input terminals on the bottom and output terminals on the top. Do not use the

unit in other mounting orientations.

Keep the following installation clearances:

- Top and bottom: min. 40mm on top, 20mm on the bottom

- Left and right:

min. 0mm if the total output current of the PISA module is less than 15A

min. 6.4mm if the total output current is equal or higher than 15A and the ambient temperature

is between 45°C and 60°C.

min. 6.4mm if the ambient temperature is above 60°C (except for PISA11.401, PISA11.402 and

PISA11.403).

A high voltage drop between the power supply and the protection module might cause a malfunction. It is not

avoid undesired undervoltage conditions on the input of the protection module.

At ambient temperatures above 50°C and output currents higher than 15A (sum of all four channels), do not use a

Use only regulated PULS power supplies to meet the conducted low frequency interference requirements when used in

marine applications according to the GL regulations (section 20 of the GL regulations).

WARNING

Risk of electrical shock, fire, personal injury or death.

- Turn power off before working on the device. Protect against inadvertent re-powering.

- Make sure that the wiring is correct by following all local and national codes.

- Do not modify or repair the unit.

- Do not open the unit.

- Use caution to prevent any foreign objects from entering the housing.

- Do not use in wet locations or in areas where moisture or condensation can be expected.

Notes for use in hazardous location areas:

The units are suitable for use in Class I Division 2 Groups A, B, C, D locations.

The units are suitable for use in Group II Category 3 (Zone 2) environments and are evaluated according to EN 60079-

0:2009 and EN 60079-15:2010.

WARNING EXPLOSION HAZARDS!

Substitution of components may impair suitability for this environment. Do not disconnect the unit or operate the

reset button unless power has been switched off or the area is known to be non-hazardous. The signal-connector may

not be used in hazardous location areas unless additional measures are met to avoid an unintended disconnection

(e.g. an additional mechanical fixation). The connection must meet the requirements of the EN 60079-15:2010. A

suitable enclosure must be provided for the end product which has a minimum protection of IP54 and fulfils the

requirements of the EN 60079-15:2010.
