2. Important Safety
Instructions
Please read the following operating instructions very carefully before using the
Electronic Ballast (EB) the first time. They contain important information and
instructions for the safety, use and maintenance of the appliance. For your own safety
please follow all safety instructions and warnings.
Keep the operating instructions carefully in a safe place and pass them to any future
owner.
2.1 Warning - High voltages inside ballast! Danger to life!
Disconnect EB from power supply before opening (pull out the line plug). Do not pull
on the connection cable, but on the plug, to disconnect the EB from mains. Any repairs
or changing of the line plug must only be carried out by qualified personnel or ARRI-
service departments.
2.2 Before connecting the Electronic Ballast ensure that the power supply is correctly
wired. Do not use without adequate earth connection unless either an isolation
transformer or an earth-leakage trip is employed.
Note: In order to avoid unwanted tripping due to leaking currents and transient
disturbances, care shall be taken that the collective leakage current of equipment on the
load side of a residual current device is less than 1/3 of its rated residual current.
The typical leakage current of this device is max 1mA (according EN 60598-1:1996,
appendix G).
2.3 Lamphead must be disconnected from Electronic Ballast and Electronic Ballast must
be disconnected from mains before fitting or replacing a lamp.
2.4 The Electronic Ballast must be switched off before connecting or disconnecting
either head or supply cable. Do not use other than original ARRI cables and connectors
with permitted cross section of the leads. The ballast can only be used with a suitable
multicore cable system (see fig. 1, page 16). Using other than original ARRI cables or
luminaires may cause injury to the user as well and/or damage to the ballast.
2.5 The Electronic Ballast satisfies the standards of the recognized state of the
engineering and the pertinent safety regulation of DIN EN 60598/1. Supply voltage must
not exceed the ranges that are given in the "Technical Data" (see page 14). Check that
the power supply voltage and wiring are suitable for the ballast to be used. Supply
voltages which are greater or less than that specified for the ballast can cause injury to
the user as well as damage to the ballast.
2.6 The electronic of the EB is built in a housing with protective class I and protective
rate IP 20. To ensure protective rate IP 20 all module slots must be equipped with
modules or suitable blind covers. A device with missing modules or blind covers must
not be put into operation.
Ambient operating temperatures must be between -10°C and + 50°C!
The air slots for ventilation at front panel and rear side should never be covered or
obstructed.
The EB must only be placed in a adequately ventilated cabinet or on solid, flat and dry
ground. Temperature of the ground should be less than 50°C. When mounting in a
cabinet slide rails with appropriate payloads have to be used.
Protect EB against direct sunshine. The EB must be protected against splash and drip-
water (acc. to protective rate IP 20).
Do not operate the EB in high humidity (dew) or in aggressive or explosive gas-air
mixtures.
