Installation
Introduction
Type RL Low Voltage AC Power Circuit Breakers may be
furnished for mounting in any one of three ways:
In switchboards or in metal enclosed switchgear of the
I.
Drawout type.
2.
In individual metal enclosures (Drawout type).
3.For stationary mounting in the user's own enclosure or
switchboard.
RL
All
circuit breakers are completely assembled, tested, and
calibrated at the factory in a vertical position and must be so
installed to operate properly. The user's primary connections
must be adequately braced against the effects of short circuit
currents to prevent overstressing the circuit breaker terminals.
Receiving and Inspection for Damage
IMPORTANT:
Do not accept the statement from any
driver that. The damaged equipment was not properly
packaged by shipper.
Do not sign Bill of Lading without notation of visible
damage if observed. Our equipment packaging meets the
rigid requirements established by the trucking industry.
You must obtain carrier inspection within
receipt on damaged equipment.
Immediately

remove all packing braces.
Examine parts and check them
against the packing list and note any damage incurred in
transit.
If damage is d isclosed, the consignee must arrange
for a carrier
inspection
within

consignee must obtain the original of the carrier inspection
report and notify Siemens immed iately.

However, a careful check should be made to be certain that
shipm�nt or storage has not resulted in damage or change of
adjustment.
Circuit breakers and their enclosures should be
installed in a clean, dry, well-ventilated area in which the
atmosphere is free from destructive acid or alkali fumes. For
stationary breakers and custom enclosures, the factory should
be consulted for minimum clearances and required ventilation
openings.
Before installing, make certain that the circuit breaker
contacts are in the open position and that the closing springs
are d ischarged. Be sure to lubricate primary and secondary
