The target group of this manual is qualified personnel of the

gas safety and regulating technology. Due to their specialist

training, knowledge and experience, they should be capable

of evaluating the work assigned to them and recognising

possible dangers. Only they are permitted to carry out as

sembly, commissioning, settings and maintenance on the

devices in compliance with the recognised rules for occupa

tional safety.

Instruction Manual

FRM 100025 - 100050

2. Warnings

Never carry out work as long as gas

pressure or voltage is applied. Avoid

open fire. Please observe public regula-

tions.

The device must be protected from vi-

brations and mechanical impacts.

All adjustments and settings should only

be performed in accordance with the

instruction manuals of the connected

machines.

The recognised occupational safety

rules and accident prevention regula-

tions must be observed and, if neces-

sary, personal protective measures must

be taken.

Connected line systems must be free

from dirt and contamination.

Hang this instruction manual in a readily visible place

inside the installation room! Do not carry out any work

until you have read the safety instructions of this in-

struction manual and are qualified to do so.

The device may only be operated in

compliance with the operating condi-

tions stated on the type plate.

Prior to assembly, the device must be

inspected for transport damage.

The device must not be used in areas

with increased seismic risk.

Protection from environmental impacts

and weather conditions (corrosion, rain,

snow, icing, humidity (e.g. by conden-

sation), mould, UV radiation, harmful

insects, poisonous, corrosive solutions/

liquids (e.g. cutting and cooling fluids

must be guaranteed. Depending on the

installation site, it may be necessary to

take protective measures.

The device must not be exposed to open

fire. Protection against lightning strikes

must be guaranteed.
