Klein + Hummel M 50, Installation & Operation Manual, Page: 2 / 8

1. Safety Instructions
It is absolutely essential that you read these safety
instructions carefully before connecting and using this
K+H product. Your safety depends on it. Furthermore,
failure to follow these instructions voids the warranty.
To
ensure safe operation for years to come, keep these
instructions in a safe place for future reference. K+H has
manufactured this product in accordance with IEC 1992 (SEC)
39 standards, then tested and delivered it in safe operating
condition. To maintain it in this condition, you must:
€ observe all safety instructions,
€ use the product only as described herein,
€ have any maintenance, repairs, or modifications performed
only by K+H or other authorized personnel, and
€ ensure that the room in which you use this product is wired
in accordance with the local electrical code.
Warning!
€ When the interior of the cabinet is exposed, touching some
parts can lead to an electric shock.
€ If you need to gain access to the interior electronics of the
unit, always disconnect the unit from any and all power
sources first.
€ Any repairs, maintenance, or other service of the unit when
its interior compartment is exposed may only be performed
safely (in accordance with VBG 4) by authorized technicians
familiar with all the risks involved. Even in an unplugged
state, a fully charged capacitor in the unit can zap the
unsuspecting.
€ Loudspeaker output jacks labeled with the IEC 417/5036
emblem (Fig. A, right) may be carrying dangerously high
voltages. If your unit has this emblem, ensure that any
connections to be made between these jacks and the
speakers themselves are made before powering up the
unit, and are done so only with manufacturer-approved
interconnecting cables.
€ If you need to replace any fuses, ensure that the
replacements are of exactly the same type, value and
voltage as the originals, as spelled out in the technical
specifications at the rear of this manual.
€ Do not use "repaired" fuses.
€ If you do not have any fuses on hand of the specified size,
type, and value, do not hot-wire the contacts in the holder
by short-circuiting them.
€ Certain areas of the cabinet, cover, and rear panel can
achieve extreme temperatures and are therefore marked
with a "HOT" label (Fig. B). Refrain from touching any heat
sink or ventilation grille.
€ High volume levels are known to cause permanent - i.e.
irreversible - hearing damage, especially when listened to
without sufficient breaks. The higher the levels, the more
frequent and extended must be the breaks. Avoid standing
too close to loudspeakers that are being driven at high
levels. If you must be exposed to high sound pressure levels
over an extended period of time, use hearing protection.
Mains Connection:
€ This unit is designed for continuous operation.
€ Ensure that the operating voltage of the unit matches that
of the local mains current (AC line voltage).
